Mike: It's easy just using quotemeta to automatically escape anything that looks dangerous. Thanks for the advice guys. I've got a simple prototype working in Perl. In the code below, both the sample texts with some arbitrary special characters match against a single 3-part regular expression.

Phone: +61-2-9335-0725, Email: [EMAIL PROTECTED] PERL CODE ========================================== #!/usr/bin/perl #Text that must be matched $sample_text1 = 'multi-line test \t with special *?#. VAR 123 characters like . \d and .$'; $sample_text2 = 'multi-line test \t with special *?#. VAR 457 characters like . \d and .$'; $text_to_match = $sample_text2; # or $text2 #Regular Expressions that will match against text $regex_1 = 'multi-line test \t with special *?#. '; $regex_2 = ' VAR \d\d\d '; $regex_3 = 'characters like . \d and .$'; #Actual matching $full_regex = quotemeta ($regex_1).$regex_2.quotemeta ($regex_3); $result = $text_to_match =~ /($full_regex)/; #Output print "----------------------------\n"; print "Text to match: $text_to_match\n"; print "----------------------------\n"; print "Quotemeta'ed Regex: $full_regex\n"; print "----------------------------\n"; print "Match result: $result\n"; print "----------------------------\n"; print "\$1 from match: $1\n"; PROGRAM OUTPUT ========================================== Text to match: multi-line test \t with special *?#.
