[xml] On validating a DOM with a schema, in Python

["Meunier, Jean-Luc" <Jean-Luc Meunier xrce xerox com>]

Hi,

 

In Python, I need to validate a DOM tree using a W3C XML schema, but I cannot figure out how to do it. 

It seems that the C-function  xmlSchemaValidateDoc does the job but  I’m lost in the Python binding.

( My (naïve) trials were in the style:

  schemadoc = libxml2.parseFile("my-schema.wxs")

  schema = libxml2.Schema(schemadoc)

  ctxt = libxml2.SchemaValidCtxt(schema)

  #ctxt.schemaParse() ??

  doc = libxml2.parseFile("test.xml")

   res = doc.schemaValidateDoc(ctxt)

)

Is there anyone around that can show me the way? (I insist, that it is about validating a DOM already in memory)

Thanks,

JL
