Thanks that did it.


I hate regular expressions (or maybe am in awe of their power) but you're my 
new best friend.

It uses the java replaceAll regex function so that it can do the negative 
lookbehind to ensure existing correct items are not changed, meaning it can be 
run multiple times.

Accepts any character (except newline) until it finds a closing A tag.

If newlines are required, that's just a one character change:

    '~\{(?s:(?!).)+(?)'

(Which adds the 's' flag into what was a non-capturing group, meaning '.' also 
matches newlines.)


If there's the possibly of a '~{' appearing outside this context, it may need 
extra limits applied to work correctly.

Assuming there should not be any tags inside the ~{...}~ part, I would change 
the '.' for a '[^<>]' which makes it a bit 'safer':

    '~\{(?:(?!)[^<>])+(?)'

This might be more of what you are looking for. It captures special

I just found an issue with this regexp



this works great if it is not the first word or only word in the string.

what do I need to do to update the regexp to pick up the bad word it is the 
first last or only word in the string also.

Thank you again for all of your help.

Forgot about Ryan Swanson's slick little tool.  It certainly validates and 
picks up the middle 'kiss' in his validator, using either '\W' or '^a-zA-Z0-9_' 
as the filter:

Re: Regular Expression help

Hm, that should work, certainly.  Did you try that 3rd option?



That should find any use of the word 'kiss' when it's surrounded by any 
non-alpha characters.  Sadly I don't have access to my CF environment right at 
the moment, so I can't test :(

Not sure what I am doing wrong but this is not working.

I have the string "kissess are goodkissthe girlfriend"

Kiss is a badword, and this regexp is not picking it up.

Please advise and thanks for your help.

Regular Expression help

[Matthew Friedman]

Please help, banging my head against a wall and my deadline is up...

I need to search a text filed of html formatted text to see if the user enter 
in "bad words"

I have it all set to go but the regexp is giving me trouble.

I am looping over the list of badwords and checking the variable skills.

]+#badword#+[\<])",skills)>

The issue is that if the word "kiss" is a bad word I need to be able to flag it 
if it is wrapped by html tags i.e. kiss the pony and I only want kiss 
not kissing.

Please help with the regexp to get this done.
Thank you in advance.

Re: Regular Expression Help on Email Addresses

[Ben Doom]

Offhand, I think your best bet is to use a regex to identify everything 
from the @ to the TLD, then use the len returned by refind to do a 
replace of it.  There are a number of really good regexes for 
finding/dissecting emails out there.  CFLib.org is a good place to start.

RE: Regular Expression Help

[Bobby Hartsfield]

That would not match 0 through 9.999 unless they were formatted into 2
digit numbers like 00, 01, etc... 09.999 It also wouldn’t match anything
between 1 and 0 like .999 unless it was formatted like 00.999

Try this one: ^\d{0,2}(\.\d{1,7})?$

I don’t know what you are using it for but there is also the possibility of
negative numbers. The above will not match them either. You could say ... if
(regex matches number OR number LT 100) to get the negatives if it matters.

cheers

^\d{2}(\.\d{1,7})?$

RE: Regular Expression Help

[Ben Nadel]

Not really sure what exactly you are looking to do, but the regular
expression pattern for numbers under 100 with 7 decimals would be:

\d{2}(\.\d{1,7})?

This makes the decimal optional (with 1 to 7 decimal places). Of course,
this does not protect AGAINST numbers over one hundred. For that you
would need to use a java-style negative look behind (not available in
standard CF RE functions):

RE: Regular Expression Help....

[Dave Phillips]

Here's what I ended up using:

https?:)\/\/))[-[:alnum:]\?%,\.\/&##!@:=\+~_]+[A-Za-z0-9\/])

Thanks to Bobby Hartsfield for that!

It seems to get everything I need and nothing I don't.  Here's the whole
function in case anyone wants it:

function extractURLs(inputString) {

var nPos=0;
var lsURLs = "";
var sDelimiter = chr(9);
var nEndPos = "";
var sLink = "";
var sRegExp =
"https?:)\/\/))[-[:alnum:]\?%,\.\/&##!@:=\+~_]+[A-Za-z0-9\/])";

if(arrayLen(arguments) eq 2) {
sDelimiter = arguments[2];
}
nPos = reFindNoCase(sRegExp,inputString);
while(nPos) {
inputString =
mid(inputString,nPos,len(inputString));
nEndPos = reFind("['#chr(34)# ]",inputString);
sLink = left(inputString,nEndPos-1);
// Remove trailing slash if it exists so we don't
end up with duplicates.
if(right(sLink,1) EQ "/") {
sLink = left(sLink,len(sLink)-1);
}
if( NOT listFindNoCase(lsURLs, sLink,
sDelimiter)) {
lsURLs = listAppend(lsURLs, sLink,
sDelimiter);
}
nEndPos = findNoCase("",inputString);
inputString =
mid(inputString,nEndPos+4,len(inputString));
nPos = reFindNoCase(sRegExp,inputString);
}

return lsURLs;
}

here as your question inspired my blog post:

Hi,

RegExp's are not my forte and I need to create a function that will
extract URL's from a body of text and return it in a list.

I have a function that extracts the anchor tags from a document, but I
need to acurately extract the URL from that anchor tag.  I can do a find
for 'href' and so on, but the RIGHT regular expression would make sure
all possibilities are covered like href=", href=' or href= or href = and
so on.

Can anyone help please?

Thanks!

Dave

RE: Regular Expression Help.... (Solution?)

Oh sorry, I didn't see the "Solution" email before I posted my last
snippet. What you are doing below is fine. I cannot attest to the RegEx.
You might want to try grabbing something of of RegExLib.com if you are
unsure. I do know you should probably check for period "." to end a URL,
but do not confuse with file extension. URLs are a tricky beast.

RE: Regular Expression Help....

[Ben Nadel]

Dave,

This snippet takes your regular expression and returns all matches in an
array:

http://www.bennadel.com/index.cfm?dax=snippets:11.view

You can then take that and convert it to a list (but I would guess
keeping it in an array is the way to go). 

After that, all you need is a good RegExp, which it looks like other
people have already provided.

Keep in mind, this snippet is for use with JAVA regular expression,
which are slightly different but same idea.

Hi,

RegExp's are not my forte and I need to create a function that will extract
URL's from a body of text and return it in a list.

I have a function that extracts the anchor tags from a document, but I need
to acurately extract the URL from that anchor tag.  I can do a find for
'href' and so on, but the RIGHT regular expression would make sure all
possibilities are covered like href=", href=' or href= or href = and so on.

Can anyone help please?

Thanks!

Dave

Regular Expression Help

[cf coder]

Hello Everybody,

I'm having problems writing a regular expression. I'm trying to pass a string 
to flash and want to strip off and replace the html tags with a  tag but 
also leave any , , , , , , and  tags. 

This is what I've done so far:


function StripHTML(str) {
return REReplaceNoCase(str,"<[^>]*>","","ALL");
}






The above function strips out any html tag and replaces it with a "" tag. 
This is fine but I want to keep the , , , , , , 
 tags and dont know how to tell it to ignore these tags and replace 
everything else with a < and > angle brackets.

Can someone please help me with this. I am just not good at this sort of things.

Thanks,
cfcoder

If all of your links are fully formed like that you don't need regexs at all
- just treat the URL as a list delimited by a forward slash ("/").

Since CF condenses multiple delimiters I think this will give you your URL:

http://www.blah.com/something/somethingelse/default.cfm " />



Using the ListGetAt() for the first part (the protocol) is important to
catch none http links like "https:" and "ftp:".

Guys,

I have the following email check but it won't accept a .info email 
address. I'm not a regular expression expert and was hoping someone 
could help me out with this. How could I update the following script to

function isEmail(str) {
   // are regular expressions supported?
   var supported = 0;
   if (window.RegExp) {
 var tempStr = "a";
 var tempReg = new RegExp(tempStr);
 if (tempReg.test(tempStr)) supported = 1;
   }
   if (!supported)
 return (str.indexOf(".") > 2) && (str.indexOf("@") > 0);
   var r1 = new RegExp("(@.*@)|(\\.\\.)|(@\\.)|(^\\.)");
   var r2 = new

RE: Regular Expression Help

[Pascal Peters]

^ beginning of string
.* any character, any number of times
<... literal string
([^"]*) any character except ", any number of times (grouped for
backreferencing)
".* see above
$ end of string

The "\1" matches the first group saved for backreferencing. I forgot the
quotes in my original post.

Pascal,

  Would it be possible for you to explain a bit more about what each part of
the RegEx is doing? I'm trying to do something similar and I'm having no end
of trouble getting the RegEx right. MM documentation is pretty thin on more
advanced matching.

Thanks,

Gavin

RE: FIXED - Regular expression help with dictionary definitions

[Pascal Peters]

Don't do the replace, just don't include the {} in the REreplace.
Although I may have overlooked something: You really should do a
URLEncodedFormat() of the word (which doesn't work with the
backreferencing). 

function MakeLinks(text,dictionary){
	var st = StructNew();
	var start = 1;
	var word = "";
	var link = "";
	while(true){
		st = REFind("\{([^{}]+)\}",text,start,true);
		if(st.pos[1] IS 0) break;
		word = Mid(text,st.pos[2],st.len[2]);
		text = RemoveChars(text,st.pos[1],st.len[1]);
		link = "
href="">
dFormat(word)#"">#word#
>";
		text = Insert(link,text,st.pos[1]-1);
		start = st.pos[1] + Len(link);
	}
	return text;
}

Pascal, you are a STAR!

 
The backreferencing wasn't quite there as I wanted to remove all of the
extra parentheses also but a simple replacelist wrapped around your elegant
solution fixed that...

This is not exactly what you are trying to say: 

[^{^}] ==> anything but { or } or ^
Correct: [^{}]

Pascal

PS Give the REReplace with the backreferencing (see my previous post) a
shot. It is only 1 line to do the same thing.

Sorry for the original and long post... I fixed it...

The regular _expression_ changed to {[^{^}]*} and I changed the startpos for
the next REFindNoCase so it skipped the nesting issues...

RE: Regular expression help with dictionary definitions

[Pascal Peters]

If this is the actual code you are using, you are creating an infinite
loop because you always start looking at the start position 1 in your
REFind. It will keep matching the first {}.

It really depends what you are trying to grab. If you are trying to get
only the inner parentheses it is not too hard. Now for the solution:

teststr = REReplaceNoCase(teststr,"\{([^{}]+)\}","{
href="">
>}","all");

Not tested, but it should work.

Regular expression help with dictionary definitions

[Paul Vernon]

Ok,

This one is killing me.. And my CFMX server...

Currently I'm using the following code to parse some text:



1, true)>

	
st.pos[1], st.len[1])>
	
len(replaceme)-2)>
	
ReplaceNoCase(teststr, replaceme, "
href="">
heword#", "all")>
	
teststr, 1, true)>


The text usually resembles something like the first example below and by the
time the parser has run, everything inside the parentheses are turned into
hyperlinks..

Fungi \Fun"gi\, n. pl. (Bot.)
   A group of thallophytic plants of low organization, destitute
   of chlorophyll, in which reproduction is mainly accomplished
   by means of asexual spores, which are produced in a great
   variety of ways, though sexual reproduction is known to occur
   in certain {Phycomycetes}, or so-called algal fungi.

   Note: The Fungi appear to have originated by degeneration
 from various alg[ae], losing their chlorophyll on
 assuming a parasitic or saprophytic life. By some they
 are divided into the subclasses {Phycomycetes}, the
 lower or algal fungi; the {Mesomycetes}, or
 intermediate fungi; and the {Mycomycetes}, or the
 higher fungi; by others into the {Phycomycetes}; the
 {Ascomycetes}, or sac-spore fungi; and the
 {Basidiomycetes}, or basidial-spore fungi.

My problem is that I have just discovered is that of nested parentheses...
Using the code above the process goes into an infinite loop and eats all
available RAM in about 30 seconds

The following text kills my algorithm!

Cryptogamia \Cryp`to*ga"mi*a\ (kr?p`t?-g?"m?-?), n.; pl.
   {Cryptogami[ae]} (-?). [NL., fr. Gr. krypto`s hidden, secret
   + ga`mos marriage.] (Bot.)
   The series or division of flowerless plants, or those never
   having true stamens and pistils, but propagated by spores of
   various kinds.

   Note: The subdivisions have been variously arranged. The
 following arrangement recognizes four classes: -- I.
 {{Pteridophyta}, or {Vascular Acrogens}.} These include
 Ferns, {Equiseta} or Scouring rushes, {Lycopodiace[ae]}
 or Club mosses, {Selaginelle[ae]}, and several other
 smaller orders. Here belonged also the extinct coal
 plants called {Lepidodendron}, {Sigillaria}, and
 {Calamites}. II. {{Bryophita}, or {Cellular Acrogens}}.
 These include {Musci}, or Mosses, {Hepatic[ae]}, or
 Scale mosses and Liverworts, and possibly
 {Charace[ae]}, the Stoneworts. III. {{Alg[ae]}}, which
 are divided into {Floride[ae]}, the Red Seaweeds, and
 the orders {Dictyote[ae]}, {O["o]spore[ae]},
 {Zo["o]spore[ae]}, {Conjugat[ae]}, {Diatomace[ae]}, and
 {Cryptophyce[ae]}. IV. {{Fungi}}. The molds, mildews,
 mushrooms, puffballs, etc., which are variously grouped
 into several subclasses and many orders. The {Lichenes}
 or Lichens are now considered to be of a mixed nature,
 each plant partly a Fungus and partly an Alga.

One solution would be to repeatedly pre-parse the text to remove or escape
the extra parentheses but I'm not inclined to do this as I believe I should
be able to fix my regular _expression_ which is currently "{[^}]*}".

Does anyone have any suggestions???

Thanks in advance

Regular Expression Help

[Ian]

I'm trying to parse a string and pluck a bit of text, but my regex
isn't working :( Here's a sample string:

(msg:"My Message Here"; content:"My Content Here";)

I want to return My Message Here.

And here's my regex:

refindnocase("msg:[[:print:]]+;", mystring)

I'm using print as mystring may contain any printable characters.

This returns 0 as the position. Any ideas?

RE: Regular expression help

regexp = "##[[:space:]]*([0-9]{2-3})";
stTmp = REFindNoCase(regexp,str,1,true);
if(stTmp.pos[1])
	result = Mid(str,stTmp.pos[2],stTmp.len[2]);
else
	result = "";


If you need to find all, you do it in a loop: 


regexp = "##[[:space:]]*([0-9]{2-3})";
results = ArrayNew(1);
start = 1;
while(true){
	stTmp = REFindNoCase(regexp,str,start,true);
	if(stTmp.pos[1]){
		ArrayAppend(results,Mid(str,stTmp.pos[2],stTmp.len[2]));
		start = stTmp.pos[1] + stTmp.len[1];
	}
	else break;
}


Probably you want to make sure that the character after the 2-3 digits
is not a digit. If so, modify the regexp to
regexp = "##[[:space:]]*([0-9]{2-3})([^0-9]|$)";

On CFMX you could use negative lookahead:
regexp = "##\s*(\d{2,3})(?!\d)";

I use:

which, admittedly, won't allow .museum addresses, but will match most

Re: I'm gonna need some regular expression help here...

[Ben Doom]

This regex was intended to be used with a case-insensitive regular 
_expression_ checker.  To make it case insensitive, there are two things 
you'll have to do.

replace a-z in brackets with a-zA-Z

replace each of aero, coop, info, museum, and name with EVERY  POSSIBLE 
CAPITALIZATION POSSIBILITY.

If I were you, I would probably do my email format validation on the 
backend.

Got a cfinput, it's required, and the validation is a regular _expression_.

The Problem: The regular _expression_ isn't allowing a capital letter after
the '@'. I'm sure there are other faults with this regular _expression_, but
you see...I'm just not "there" yet when it comes to troubleshooting these

RE: Repost: Regular Expression Help

[Ben Doom]

Well, there are some things you can do here, but nothing's going to be
perfect.

Let me restate:  it would be more work to create a regex to handle every
case than to just to a find & replace on things.

Start with the most complicated common case.  Let's say it's a td with a
width.  Your regex might look something like this:


The problem is that there's no really good way for you to define how much
the regex should match, since there are a really wide variety of things you
can stick in a td, both legally and otherwise.

Anyway, I'd start with your most complicated case and work back down to a
plain td.  From there, you ought to (hopefully) be able to tweak it by hand
fairly easily.

If not, or you want to explore this more thoroughly, or just want a better
explanation of how the regex works or whatnot, I'd point you to the CF-RegEx
list, where Ninjas are standing by.  Seriously, there are several guys over
there who, between us, generally can take on just about anything:

I'd use
[[:punct:] ]
as the class if you only need to check spaces -- if you need vertical tabs,
carriage returns, tabs, etc. use
[[:punct:][:space:]]
which should give you something like
newstring = rereplace(string, "[[:punct:][:space:]]", "_", "all");

Of course, it might be easier (as Rob suggested) to think about what
characters you want to allow instead of disallow:

newstring = rereplace(string, "[^a-zA-Z0-9_]", "_", "all");

would only keep letters, numbers, and underscores.

reReplace(string, "[[:punct:]]|[[:space:]]", "_" "ALL") on 'some phrase'
returns '_some_phrase_' which was not expected.  The string 'some
phrase' really is just that without any extra spaces.

Either way, the first method works just fine and is probably safer.

Did you TRIM the variable first? That may help ... Perhaps there's
whitespace surrounding the text.

Try: ReReplaceNoCase(trim(variable),"[^A-Za-z0-9]","_","ALL")

When I use your before mention snippet, I am getting an underscore
character tacked onto the beginning and ending of each word.  There is
no space or any other character their, but after executing the regex
statement, I have underscores before and after.

[[:punct:]]|[[:space:]] on 'some phrase' returns '_some_phrase_' instead
of 'some_phrase' which is what I was looking for.

Re: regular expression help

[Michael Dinowitz]

If you have a limited range of accepted tags then the following will probably be your 
best bet. 
1. find all of the tags you want to allow. 
2. replace their brackets with some non-standard character (like a yen symbol). 
3. remove all other tags that exist.
4. replace your yen with brackets again.

RE: regular expression help

[Tangorre, Michael]

Mark,

I am fairly new to RegEx, but I can tell you we did this on our University's site when 
I was in college.
We allowed the different departments to submit formatted text using an assortment of 
HTML tags that we specified.
We used RegEx to do this, and did not notice a performace hit at all.

For what that's worth...

Mike

RE: Regular Expression Help

[Pascal Peters]

lWordList = ArrayToList(myarray,"|");
REReplaceNoCase(mystring,"([^[:alnum]])(#lWordList#)([^[:alnum]])","\1\3"
,"ALL");

This will replace the words defined in myarray by empty strings.

If you want to use regular expressions to do it, easiest way would be to
use the character class for whitespace before and after your
preposition.

However don't underestimate the power of the CF list processing
functions, think of your search term as a list seperated by whitespace
and you can use any of the CF list functions.

Re: Regular Expression Help

[Douglas Brown]

just do a udf and create your array and then check that the value of the 
words you are replacing (length). If they are less than 4 char then they 
should be removed. Hope that makes sense.

Or you could use ListReplace with " " as the delimiter -- as long as you
force everything lower case first.
