[xml] [python] DOM object from file with parsing options

[Nicolas Mazziotta <nicolas mazziotta skynet be>]

Hello,

I am trying to create a DOM object from a file and to navigate it with xpath 
queries. I have to turn off entity declaration and therefore use parser 
options. It means that I cannot use the parseFile() method.

When I create the parser, configure it and run it on my test.xml file, it 
parses well, but xpath queries all return nothing, except for queries that 
use no tag name ("/", "/*/*" and the like). Any idea about what goes wrong?
        
#############
PARSER_OPTIONS = libxml2.XML_CHECK_NOT_ENTITY_DECL

parser=libxml2.createFileParserCtxt("test.xml")
parser.validate(0)
parser.ctxtUseOptions(PARSER_OPTIONS)
parser.parseDocument()
xmlDoc = parser.doc()
ctxt = xmlDoc.xpathNewContext()
for seg in ctxt.xpathEval("//seg"):
        print seg.prop("subtype")
        print seg.prop("function")
#############

Thanks for any help.
