What I did in the Image Uploader was generate Python bindings from the OVF XSD using GenerateDS. GenerateDS has a fairly active community and a wildly helpful maintainer. The Python binder is similar to the Java binder (JAXB). You feed it an XML schema and it will generate bindings that enable you to marshal XML into objects vice-versa. There is no need to muck around with LXML and ugly looping which is typical for XML parsers. You work with nice clean objects. My recommendation would be to create an oVirt OVF library which is based off bindings from GenerateDS. You implement the methods that make sense to oVirt and skip the *very* large subset of the OVF standard that is not applicable to oVirt OVF images. Such a library could be used by the Image Uploader and any other components that require OVF processing capabilities. I would be happy to work with you on abstracting the binder away from the Image Uploader so that it could be re-used in other components if you are interested. Keith
