RE: [PHP] Pattern-Matching For Replacing Text

Hi Jeff, regular expressions are a powerful tool in programming, but not easy to learn at first sight. If you're really interested in learning them I'd suggest you get the book 'Regular Expressions' by Jeffrey E.F. Friedl http://www.oreilly.com/catalog/regex/ aka 'The Owl Book'. You can also find some reference in the PHP manual: http://www.php.net/manual/ref.regex.php http://www.php.net/manual/ref.pcre.php and additionally here: http://www.perl.com/reference/query.cgi?regexp When you read this, then you'll understand why nobody can really give you any help here with your specific regex problem, without knowing the exact structure of the document. Anyways '%' is not a wildcard in a regex it is '.*'. Matthias aka Matthew -- $ [ Where is Jimmy Hoffa?
