Probably it's best to use XPath expressions, see for example src/input_libvirt.ml. If you need new libxml2 APIs to be added to src/xml-c.c then you can have a go yourself or ask Pino to write any you need.

Re: [Libguestfs] do we have support for xmlns in xml for v2v?
I don't think I've parsed a namespaced document using xpath before, but according to: https://stackoverflow.com/questions/3135175/libxml2-error-with-namespaces-and-xpath it looks like you'll need a binding for xmlXPathRegisterNs.
