in reply to How I can change value in XML file ?

FYC: XML::LibXML has sparser docs and fewer tutorials than the very capable XML::Twig but it is a widely used lib underneath and if you learn its API, you'll be learning things that can transfer to many other places.

    Maybe I'm just "different", but in my own experience, the man pages that come with XML::LibXML are actually easier to use than the manual for XML::Twig. (Sometimes "less is more": another way of saying that the LibXML docs are "sparser" is that they are more concise).

    Apart from that, LibXML runs a lot faster, and tends to impose a much smaller memory footprint when it comes to handling a large XML structure.

      Yeah, in fact. Now I find the XML::LibXML docs quite nice but when I was starting with it way back when it was maddening. You need a decent understanding of the DOM and iterators and such to know which of the many docs to check. Once you do, they're great. Before that… uh… wha?

        When a ::Parser object parses a document, it returns a ::Document object. A ::Document object holds a tree formed of ::Node objects. The ::Node class is the base class of everything in the tree, including ::Attribute objects (which represent attributes) and ::Text (which hold the text body of elements). You'll deal primarily with ::Element objects, which represent XML elements.

      Yeah, if you misuse XML::Twig and force it to keep the whole file in memory.
