in thread Which XML parser would be the wisest to use

Thanks, runrig

I actually set 

$XML::SAX::ParserPackage
in my SAX test and gave each of the modules a go. ExpatXS was the fastest, so I just used it.

I thought XML::LibXML was a tree parser and I have had little luck with them as I run out of memory and my windoze session grinds to a halt :-(

I quite like the feel of SAX and might just put up with the penalty but I wanted to get some opinions before just ploughing ahead and coding all the parsers I need.

BTW, PurePerl took a lot longer. Here's the original run where I timed a few of the SAX modules :)

XML::LibXML::SAX

sys     0m0.312s


XML::SAX::Expat

    XML::LibXML can be a purely SAX parser (XML::LibXML::SAX) if no DOM functions are used. XML::LibXML::SAX::Parser on the other hand says that it builds the DOM and then generates SAX events.

      I'm afraid of the

      At the moment XML::LibXML provides only an incomplete interface to libxml2's native SAX implementation. The current implementation is not tested in production environment. It may causes significant memory problems or shows wrong behaviour. If you run into specific problems using this part of XML::LibXML, let me know.
      note in the XML::LibXML::SAX's docs. I might have based XML::Rules on this module if it was not for the message. Until the module's authors remove the message I don't think I'll switch, though if anyone wants to attempt rewriting XML::Rules on top of SAX I don't mind and would do my best to help.
