sorry i noticed the regex i pasted was wrong, shaould have been (<script[^>]*>)([^<]*)(</script>) 
 
yes if you use comments (i dont) it will be hard.
 
perhaps just two REFindNoCase() calls
 
1. (<script[^>]*>)
2. (</script>)
 
and then match up the arrays returned to get the start and end points of each block in the source

remove the (?i) and try, also remove the comment tags i never use them doesn't seem to bother anyone

well thats just it
 
what do people usually do in there script blocks?
 
<script>
    <!--
 
    -->
</script>

works fine, but in 4.5 produces nothing

Subject: [cfaussie] Re: regular _expression_

problem in earlier versions was that you couldn't specify 'greedy' (*) or 'not greedy' (*?) matches to tell it how far to go. So the below would match on the final </script> on the page and there may be more than one
 
Also not sure if the case insensitivity flag (?i)  works either
 
try (<script[^>]*>)(^(</)*)(</script>) but hope your js doesn't need the  char '<' - you can test this in homesite/studio - it appears to be similar to the cf5 syntax

from docs

The regular _expression_ quantifiers ?, *, +, {min,} and {min,max} specify a minimum and/or maximum number of instances of a given _expression_ to match. By default, ColdFusion locates the greatest number characters in the search string that match the regular _expression_. This behavior is called maximal matching.

For example, you use the regular _expression_ "<b>(.*)</b>" to search the string "<b>one</b> <b>two</b>". The regular _expression_ "<b>(.*)</b>", matches both of the following:

  • <b>one</b>
  • <b>one</b> <b>two</b>

By default, ColdFusion always tries to match the regular _expression_ to the largest string in the search string. The following code shows the results of this example:
