Question

How to append an exsiting pugi::xml_node into another one using pugixml ? the only function that i know is :

Answer 1

You should use cloning functions described here:

http://pugixml.org/docs/manual.html#modify.clone

Note that cloning functions can't clone the entire document - i.e. if you have a document that's loaded from this data:

<node><child /></node>

Then if you want to clone this data into <child> node, you should do:

doc.child("node").child("child").append_copy(doc.child("node"));

This will yield the following document:

<node><child><node><child /></node></child></node>
