Yes, I tend to agree that parsing the XML is a pain. On the other
hand you can write the functions above pretty quickly using libxml2
and XPATH. Perhaps the easiest solution is some example code?
There are simple XPath wrappers for libxml2 in the src/xml.c module.
Things like virXPathString, virXPathNumber or virXPathNode.
