yeah that could work but am looking at the code being able to be converted to php and asp easily fo a regular _expression_ would be easiest to move across, plus I would prefer a regular _expression_ anyway.

Hi Steve,
 
I hate regexp, so I won't attempt to decipher yours.
 
Would it be an option to do a replacenocase on the html code, changing the first </script> to some other unique string?
Then use the regexp with the modified unique string.
 
Alternatively, you could do a findnocase on <script> and </script>, and then use the mid function to extract the code.
 
Probably less efficient, but would work.
 
HTH,
Phil.

Hey guys
 
Got a quick regular _expression_ question
 
What I am trying to do is extract all the <script> blocks from a html page.  This is what I have so far
 
<[sS][^>]*>([\w\W\S\s]*)(</script>)?
 
no whats happeneing is if there is more than one script block on the page, its grabing the script block and everything in between
 
for example
 
==========================
<cfsavecontent variable="bla">
<script language=_javascript_>
hasMsgr = 0;
function dontGotIt(){
  hasMsgr = 0;
  document.login_form.hasMsgr.value=0;
}
function doGotIt(){
  hasMsgr = 1;
  document.login_form.hasMsgr.value=1;
}
 
</script>
xxxxxxxxxxxxxxxxxxxxxxxxx
<script language=_javascript_>
hasMsgr = 0;
function dontGotIt(){
  hasMsgr = 0;
  document.login_form.hasMsgr.value=0;
}
function doGotIt(){
  hasMsgr = 1;
  document.login_form.hasMsgr.value=1;
}
 
</script>
</cfsavecontent>
<cfset scripts = ArrayNew(1)>
<cfset ArrayCounter = 0>
<cfset regExp = "<[sS][^>]*>([\w\W\S\s]*)(</script>)?">
<cfset stuff = REFindNoCase(regExp,bla,1,true)>
================================
 
like this, its getting all of the content and is looking at the last </script> tag as the closing tag rather than looking at the content containing 2 script blocks.
 
any ideas on how to get this working?
 

Regards
