Regex help

System

I'm trying to rebuild an HTML index from an IPL script. Common, right? What I'm having a hard time with is having the following STRING REPLACEMENT validate for the given string below. This is an EXAMPLE -- I am not posting TS documentation:

STRING REPLACEMENT
$txt =~ s/<!-- BEGIN $someVar -->(.*)<!-- BEGIN /<!-- BEGIN $someVar -->$1$insertedTxt<!-- BEGIN /g;

SAMPLE TEXT

<!-- BEGIN GLOBAL -->
<!-- BEGIN 6.5TSa -->
                <UL>
                        <LI><STRONG>TEAMSITE 6.5 ADMIN DOCUMENTATION</STRONG>
                        <UL>
<!-- BEGIN SUB tfo.563.rn.pdf -->
                                <LI>6.5TSa: PDF Support Library (<a target="_blank" href="tfo.563.rn.pdf">produced May 9, 2005</a>)<br><br></LI>
<!-- END SUB tfo.563.rn.pdf --></UL>
  </UL>
<!-- END 6.5TSa -->

I'm basically trying to insert some string just before "<!-- BEGIN SUB tfo.563.rn.pdf -->". Any help greatly appreciated. Regex's make me dizzy sometimes.

I think you need to use the 's' and/or 'm' modifiers for the regex to be able to handle multi-line processing - this is assuming that the sample text has all be slurped into a single string variable - e.g.:$txt =~ s|(<!--\s*BEGIN\s*$someVar\s*-->)(.*?)(<!--\s*BEGIN\s*)|$1$2 $insertedTxt$3|gsm; (untested - this is just off the top of my head).
