Hi,
I need to parse xml (vmware ovf) which have a namespace.
Attached the ovf file.
Yes, libxml2 should be able to handle any aspect of XML.
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.
Rich.
Thanks,
Shahar.
