Newbie Regex Question

I have the following strings possible:
<division /> some text string
some text string <division /> some text string
some text string <division />.

I need to replace the string <division /> with <global>division</global>
BTW, <division /> is just one example...others could be <companyname />, <attention /> etc.
so I would like to replace the < and the /> with <global></global>
just not having much success...

btw, you could use some kind of '(division|companyname|attention|whatever)' regexp to define exactly what you want to match, if you don't need to match all tags...

.. replace the < and the /> with <global></global>

Instead of trying to use REGEX, why not just use string replacement?  Easier, I would guess! ~Ray

Well...I could do that, but the string could also contain this:
<BULLETLIST><BULLET>some text value <division /></BULLETLIST>
I should have made that clear...so I guess what I need is a way to tell if < & /> are in the same string? sorry to be so dense...

One other thing...the string <division /> could also be more than one word...like <company name />...that throws a wrench into also...

Ok...here is my solution but I don't think it is that elegant...hoping someone else has a way to simplify it:

<cfset str = "My company: TEST <company name />">

<cfset str = rereplace(str,'(<.[^(><.)]+>)','<global>\1</global>',"ALL")>

<cfset str = rereplace(str,'><','>',"ALL")>
 
<cfset str = rereplace(str,' />','<',"ALL")>
 
does the trick but can it be improved?

Unless you are doing thousands of these per minute, I would not worry much about improving the process.  It may not look "elegant" on paper, but it's effective and easy to understand! ~Ray

I don't know any coldfusion, but in pure regexps what you want would be :

'' s,<division />,<global>division</global>,g ''

(try it with :
 echo "some text string <division /> some text string" | sed "s,<division />,<global>division</global>,g"
on a unix command line)

usually most languages give a regexp module that can process regexps like that...

the syntax of this is :

s/<string to be replaced>/<replacement string>/

the '/' character has to be there 3 times but can be replaced by any character (that's the position and the repetition of that character that is important) and you can append 'g' at the end, so every occurence of the string on a line is replaced.

Hope it'll be useful for you and given what you want ;)

zmo...doesn't seem to work correctly in the coldfusion rereplace function that I need to use...but I have a solution that I came up with that seems to have done the trick:
<cfset str = "My division name is: <division />">
<cfset str = rereplace(str, '(<[A-Za-z0-9]+ />)','<global>\1</global>','ALL')>
<cfoutput>#str#</cfoutput>

well, that was obvious it wouldn't work as is... what I told you is the "general" (ie POSIX) regexp syntax.
Glad to see you found your way in their implementation...

And as far as I can see, they've done a pretty neat implementation of standard regexps :)

Yea...that's a good suggestion...I've been spending a lot of time lately getting up to speed with regex's and I'm seeing that there are often multiple solutions to a problem...a great resource I'm using is the o'reilly book "Mastering Regular Expressions". Thanks zmo for your input...
