Re: Regular Expression Help
If you'd like you can use the underlying java implementation of replaceAll.

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)'

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 ).

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.

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.

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 (/).

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.

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.

if(stTmp.pos[1])
result = Mid(str,stTmp.pos[2],stTmp.len[2]);

/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);

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:

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
I have a field that will be populated with a first name and a last name, what I want to do is make sure that the first letter of the first last name is uppercase and that all others are lower case. Could someone help in a reg expression that will do this? I'm having problems finding ways of detecting/converting case using CF regexes too (doing tags to lowercase for XHTML markup). From what I've gathered, Perl regexes can do this but CF can't. Bah. There is a Perl-compatible regex parsing extension tag for CF Server at http://www.rixsoft.com/ColdFusion/CFX/PCRegEx/, but I've not bothered with this. I'm plodding along with loops and substring extraction fiddliness. Of course all I'm doing is LCase() to certain substrings. Shame there's no Capitalise() CF function.

RE: Regular expression help
Use the UDF: capFirstTitle()
http://www.cflib.org/udf.cfm?ID=116
For your purpose, CF RegExp won't do it as well as what Ed Hodder
implemented with his UDF.
But, FYI, REFind() and REFindNoCase() can return subexpressions.
Example:
Variables.sttREFind = REFind([[:graph:]]+, Variables.strName, 1,
true);
If (Variables.sttREFind.pos[1] GT 0) {
Variables.strFirstWord = Mid(Variables.strName,
Variables.sttREFind.pos[1], Variables.sttREFind.len[1]);
} else { // nothing found
Variables.strFirstWord = ;
}
See how messy this can get? The UDF has a much more elegant solution, in
my opinion. :)
Of course, RegExp has its uses. In your case, it isn't the most optimal
solution.
James.

You could just find the first head, store the position, find the next head, store the position, and then just use mid(string,pos+6,pos-1) to strip the middle out maybe there is a more efficient way Brook At 11:32 PM 08/11/01 +, you wrote: The code I'm doing now is actually in JS, but I'm having a general CF/JS regular expression learning binge, and I've hit a brick wall - can anyone help?!

Try using cfset string=rereplace(string,(head)[[:print:]]*(/head),,all) That should find anything with a beginning of head and an ending of /head and strip them out and any printable character in between with an empty string.

The middle bit is the problem - how do I match zero or more characters up to the point where you find /HEAD? Putting /HEAD in parentheses and negating it with a carat seems to only work if there are no characters between in tags that appear in /HEAD. So HEAD12345678/HEAD will be stripped out fine, but HEAD1234567d/HEAD gets left in.

Dain, thank you very much. Is it safe to assume then that anything else i want to search for can be added by placing the definition inside another pair of brackets? Yeah, square brackets define a class to match against, and clasess are or'ed together. [^ ] would match everything that wasnt a space too. ~~ Structure your ColdFusion code with Fusebox.

Re: Regular Expression Help
John,
Your assumption is correct. The part that may have confused you originally
is that POSIX-style character classes (ie, [:punct:]) are surrounded by
brackets and colons, in addition to the bracket set that defines the entire
character class, such as [[:alpha:][:punct:][:cntrl:]] etc...
Numeric charcter classes are special in that you can use a hyphen for any
range of numbers, such as [0-9], [0-3], [3-7], etc. which emcompass every
number in that specific range.

You almost had it (too many brackets):

Alpha characters or punctuation were found.
cfelse
No alpha characters or punctuation found.

If you need to get the position of the first occurance of these

use subexpressions:
cfset mystring = 1234.ABCD
!--- Use the 'returnsubexpressions' parameter to get the position ---
cfset something = REFindNoCase([[:Alpha:][:Punct:]], myString, 1,

i've written code that checks to see if there is either a letter or a
punctuation mark in a string, but it's not returning results properly.
here's the code:
cfset something = REFindNoCase('[[:Alpha:]][[:Punct:]]', myString)

Re: Regular Expression Help
Being a Perl programmer also, this is one of the things that really
frustrates me about CF's regular expressions.
Okay, so back in the day, Allaire decided to go with POSIX-style character
classes. That still doesn't explain to me why you have to put the extra
square brackets in there, and it doesn't explain why I can't write:
[:digit:]{3}-?[:digit:]{4} to describe a US-style telephone number
without an area code. I work with three different software packages that
all support regular expressions, but there's nothing regular about
them. They all use different notations, they all have quirks, and I still
have to look it up in order to remember which regular expression I'm
using.
Maybe I'm missing something, but I haven't been able to take my knowledge
of regexp that I learned from Perl and apply it to CF with any semblance of
consistency.

Re: Regular expression Help
Re: use of regular expressions for parsing html One can reliably use regular expressions to parse html if it is html that you have direct and full editorial control over. That is, if you hand edit the html, AND you can keep all your requirements in mind, then you can use with some success regular expressions to parse html. Otherwise, if you are trying to parse pages from the net, you can be pretty certain to run into serious stumbling blocks (ie the perverse things people and applications do in the name of writing or generating html). For instance, if I knew that the meta tag would _always_ be the format you described, I use a regular expression like content="([^"]*)" and know that the stuff between the parens would be what I wanted. However, I see html all the time that adds newlines arbitrarily at white space... which means that you have to somehow make certain that you know where to stop parsing... -- Larry W.

RE: Regular expression Help
This works.
CFSET theString = "meta name=""pubdate"" content=""Fri, 23 Mar 2001
07:00:00 GMT"""
CFSET st = reFindNoCase("(content="")(.*)(GMT"")",theString,1,"TRUE")
CFOUTPUT#mid(theString,st.pos[3],st.len[3])#/CFOUTPUT
The two pieces are:
1) Creating the regularExpression
2) understanding the use of the "return subexpressions" attribute of reFind;
check the documentation. I learned something just now about using it with a
paren-ed regular expression.

Yeah, of course it is ;)
Secondly, I'd suggest three replaces:
1. Replace application.cfm with an easily recognisable other string without
application in the name.
2. Replace "([^a-zA-Z0-9])application.([a-zA-z])" with "\1request.\2".
3. Replace the funny string with application.cfm again.
Yeah, that's a good idea. I'll use
([^a-zA-Z0-9])application.([a-zA-z]) instead, though, since
"application." is often the end of the sentence in the text of the
website, and it's sometimes followed by a tag.
I'm still curious about the regex, though, since I'm trying to learn
regexes. Although I will use the above method for now, I would like to
ask any experts on the subject if they could slap a single regex
together for me. It doesn't need to replace anything, but I'm very
curious about the matching regex--how do you exclude a certain string
("cfm"), a space (" "), AND a "" from matching (see my original
question below).
If you care to refer to the book, "Mastering Regular Expressions," I
have it.
Thanks for indulging me,
