Regular Expression Help
I have a regular expression issue.
I have information that says:
~{Test Information/a/li
That in a series of processing should look like ~{Test Information}~/a/li
Any idea in a rereplace how I can replace anything that is ~{*/a/li with
~{*}~/a/li
Thanks
Pat

Re: Regular Expression Help
If you'd like you can use the underlying java implementation of replaceAll.
Cfset str = ~{Test Information2/a/li~{Test Information/a/li~{Test
Information4/a/li~{Test Information/a/li /
cfdump var=#str.replaceAll( ([a-zA-Z0-9])/a/li, $1}~/a/li )#
/
Should show: ~{Test Information2}~/a/li~{Test
Information}~/a/li~{Test Information4}~/a/li~{Test
Information}~/a/li

Re: Regular Expression Help
This might be more of what you are looking for. It captures special
characters as well and should fit more in line to what you want.
Cfset str = ~{Test Infor$%mation2$/a/li~{Test
Information/a/li~{Test Information4/a/li~{Test Information/a/li
/
cfdump var=#str.replaceAll( (~\{.*?)/a/li, $1}~/a/li )# /

Re: Regular Expression Help
Give this a go:
cfset Result = InputText.replaceAll
( '~\{(?:(?!/a).)+(?!\}~)(?=/a/li)'
, '$0}~'
) /
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:(?!/a).)+(?!\}~)(?=/a/li)'
(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':
'~\{(?:(?!/a)[^])+(?!\}~)(?=/a/li)'

Regular Expression help
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. cfif REFindnocase(([\]+#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. brkiss the pony/br and I only want kiss not kissing. Please help with the regexp to get this done.

Re: Regular Expression Help on Email Addresses
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. --Ben Doom K Simanonok wrote: I would like to use a regular expression to camouflage email addresses in a forum I'm building.

RE: Regular Expression Help
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):
(?!\d{1})\d{2}(\.\d{1,7})?(?!\d{1})
This should make sure you only find the valid numbers ( I think ).

Not really sure what exactly you are looking to do, but the regular

\d{2}(\.\d{1,7})?
I'd anchor it, assuming that this is supposed to be the whole string:
^\d{2}(\.\d{1,7})?$

RE: Regular Expression Help
That would not match 0 through 9.999 unless they were formatted into 2
digit numbers like 00, 01, etc... 09.999 It also wouldnt 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 dont 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.

Here's what I ended up using:

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,

be any faster or more efficient (or if I'm missing something) I'd appreciate
it. To find the end of the URL I'm looking for a single quote, double quote or
space.

RE: Regular Expression Help....
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. ..

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.

Regular Expression Help
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 br tag but
also leave any b, span, i, strong, div, br, and p tags.
This is what I've done so far:
cfscript
function StripHTML(str) {
return REReplaceNoCase(str,[^]*,br,ALL);
}
/cfscript
cfse logtext = tabletrtdpThis is not real text/p/td/tr
trtdbFriday 17 march, 2006/b/td/tr/table
cfset str = StripHTML(logtext)
The above function strips out any html tag and replaces it with a br tag.
This is fine but I want to keep the span, i, b, strong, div, br,
p 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

Guys,
I have the following email check but it won't accept a .info email

accept domain suffixes other than .com, .net .org?
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;

Regular expression help with dictionary definitions
Ok,
This one is killing me.. And my CFMX server...
Currently I'm using the following code to parse some text:
cfset teststr = definition
cfset st = ReFindNoCase({[^}]*}, teststr,
1, true)
cfloop condition=st.pos[1] GT 0
cfset replaceme = mid(teststr,
st.pos[1], st.len[1])
cfset theword = mid(replaceme, 2,
len(replaceme)-2)
cfset teststr =
ReplaceNoCase(teststr, replaceme, a
href="">
heword#/a, all)
cfset st = ReFindNoCase({[^}]*},
teststr, 1, true)
/cfloop
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 \Fungi\, 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*gami*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
Paul

RE: Regular expression help with dictionary definitions
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,\{([^{}]+)\},{a
href="">
},all);
Not tested, but it should work.

This is not exactly what you are trying to say:
[^{^}] == anything but { or } or ^
Correct: [^{}]

RE: FIXED - Regular expression help with dictionary definitions
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 = a
href="">
dFormat(word)##word#/a
;
text = Insert(link,text,st.pos[1]-1);
start = st.pos[1] + Len(link);
}
return text;
}

RE: Regular expression help
cfscript
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 = ;
/cfscript
If you need to find all, you do it in a loop:
cfscript
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;
}
/cfscript
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'm gonna need some regular expression help here...
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
things, so I thought I'd paste the relevant portion here hoping for some,
miracle regular _expression_ person to jump in and gimme a hand.
Ready?
Here it is:
validate=regular_expression
pattern=^[_a-z0-9-]+(\.[_a-z0-9-]+)[EMAIL PROTECTED](\.[a-z0-9-]+)*\.(([a-z]{2,3

Re: I'm gonna need some regular expression help here...
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 EVERYPOSSIBLE
CAPITALIZATION POSSIBILITY.
If I were you, I would probably do my email format validation on the
backend.

Subject: Regular Expression Help
I am trying to use a regular expression to change all
possible special characters in a string to underscores
because I am trying to use the string as a variable name.
Regular expressions are not my specialty and I am running
into problems using some characters in my reReplace function.
Could somebody offer some suggestions on making this work?
I am needing to replace !@#$%^*()-+={[}]|\:;',.?/ plus a
blank space, all with the _ character.
Thanks

How do you not replace a non-existent space before and after the string?
Everything else works great.

I think you accidentally doubled the pipes between the punct and space. It
should be:
[[:punct:]]|[[:space:]]

RE: Regular Expression Help
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.
As always, the plug for the RegEx list:

regular expression help
Hello, I've got a form field in which I want to allow people to enter HTML tags (formatted stories for the web), but only a limited set of them such as heading, bold, and italic tags so that they don't mess up the overall formatting of the page. What I'd like to do is automatically strip out any other HTML tag (or JavaScript, CSS, DHTML, etc.) from the submission but leave the safe tags. I'm thinking that using a regular expression string to do this would be the way to go, however there is something to consider about that idea. The data ends up in an NTEXT field in the SQL database which is capable of storing a lot of data and I suspect people might be typing as much as a few pages of text into this field. So I'm worried that a regular expression might take too long to parse through all the entered text. Perhaps I'm missing something obvious here.

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.

Re: regular expression help
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.

What I'd like to do is automatically strip out any other HTML tag (or JavaScript, CSS, DHTML, etc.) from the submission but leave the safe tags. I'm thinking that using a regular expression string to do this would be the way to go, however there is something to consider about that idea. The data ends up in an NTEXT field in the SQL database which is capable of storing a lot of data and I suspect people might be typing as much as a few pages of text into this field. So I'm worried that a regular expression might take too long to parse through all the entered text. Perhaps I'm missing something obvious here.

lWordList = ArrayToList(myarray,|); REReplaceNoCase(mystring,([^[:alnum]])(#lWordList#)([^[:alnum]]),\1\3 ,ALL); This will replace the words defined in myarray by empty strings. -Original Message- From: James Sleeman [mailto:[EMAIL PROTECTED]] Sent: zaterdag 2 maart 2002 13:29 To: CF-Talk Subject: Re: Regular Expression Help On Sat, 2002-03-02 at 10:10, Jared Stark wrote: Hello all.

Re: Regular Expression Help
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.
