Hey,
I am trying to process XML schema documents using namespace aware SAX handlers. Currently I am using the default python 2.3 parser:
parser = xml.sax.make_parser() parser.setFeature(xml.sax.handler.feature_namespaces, 1)
At some point I need to parse xml attributes which contain namespace prefixes as their value. For example:
<xs:element name="hello" type ="xs:string"/>
The default SAX parser does a good job on dealing with qualified names as xml tags, but is there a way I can access the internal sax mapping between prefixes and full namespaces to be able to parse "qualified attribute values"? A simple private dictionary prefix2namespace would be sufficient.
Or is there a way I can tell the parser to do so for me? I tried to keep track of namespace declarations myself with the handler, but if you use namespace aware parsing startElementNS() omits those declarations from the resulting attribute list of that method.
Parsing the following XML bit:
<mapping xmlns:dwc="http://www.namespacetbd.org/darwin2"; />
does not produce any attribute with startElementNS()
def startElementNS(self, name,qname,attrs):
print "Name:%s QName=%s, Attributes=%s"%(unicode(name),unicode(qname), unicode(["%s=%s"%(k,v) for k,v in attrs.items()]) )
results in
Name:(None, u'mapping') QName=mapping, Attributes=[]
Should I maybe try another parser than the default one (Expat?)
Thanks for any help, Markus
