in reply to XML Module Recommendations

In terms of general resourcesyou can have a look at the Perl and XML FAQ and Kip Hampton's column.The Module Reviewson this site also include quite a few nodes about XML modules.

More specifically, I don't think there is any module that will satisfy all your criteria but lets list the main candidates amongst the tree based modules:

Those are the main tree-based modules, all of the SAX modules work are event-based. BTW XML::SAX::PurePerl would probably be too slow for a 10M file so it is likely that you might no be able to use a pure Perl solution.

In the end I would think that XML::Twig (surprise ;--) or XML::LibXML are the best choices, unless you can use XML::Simple. It also depends on the kind of XML you are dealing with (data or document).
