in reply to Re^2: XML parsing vs regex
in thread XML parsing vs regex

Its an assumption, I grant you, but I think I'm on safe ground when I think that building a DOM tree out of a document, followed by an XPath search is very likely to be more time consuming than a single regex pass. ;-)

I would be curious to see how close various approaches get though, so if anyone is willing to benchmark say LibXML, XML::Twig and regex, I would like to see the results

If you spot any bugs in my solutions, it's because I've deliberately left them in as an exercise for the reader! :-)
