According to the “SEE ALSO” section of the documentation for XML::DOM:

XML::LibXML also provides a DOM Parser, and is significantly faster than XML::DOM, and is under active development.

In addition, Task::Kensho::XML recommends the XML::LibXML module. So that’s the one I’d choose.

Hope that helps,

want to parse a XML file(in my case : very large XML file) and do certain modifications to its elements.

twig_handlers is the method you look for to process a large file without loading it in memory, see XML_Twig_101_Processing_an_XML_document_chunk_by_chunk

There are no rules, there are no thumbs..

What is the basic difference between XML::libXML and XML::DOM modules?

XML::DOM is a perl module. It uses/depends on XML::Parser/libexpat. Xpath support via third party XML::DOM::XPath

XML::LibXML is just an interface to gnomes libxml2 which is written C and supports DOM/xpath natively.

LibXML is faster and more memory efficient, but before strawberryperl wasn't as easily install-able on windows as XML::DOM

which one should I use?
