Hi everybody,
I'm trying to sign a XML document with a non-prefixed namespace, which is the default one. Well, in fact the problem neither is in the signature nor in the verification, but is a XPath problem. When I try to get a DOMNode * from a valid XPath, I always got an error telling that the node does not exist... The problem is the default namespace, I think, but I don't know how to solve it.
I'm working with a XML like this:
<?xml version="1.0" encoding="utf-8" standalone="no" ?>
<QUERY xmlns="http://inti.notariado.org/XML" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<REQUEST ID="REQUEST">
<HEADER>AFASFA</HEADER>
</REQUEST>
</QUERY >
If I ask for the /QUERY/REQUEST I got an error, but if I named the namespace, the problem disappear. I mean this:
<?xml version="1.0" encoding="utf-8" standalone="no" ?>
<ns1:QUERY xmlns:ns1="http://inti.notariado.org/XML" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ns1:REQUEST ID="REQUEST">
<ns1:HEADER>AFASFA</ns1:HEADER>
</ns1:REQUEST>
</ns1:QUERY >
Now I can ask for /ns1:QUERY/ns1:REQUEST without problems, but this is not what I want.....
Do you know if exists an easy way where I can select a node from a valid XPath within a default namespace?
My code which returns the node from a XPath is the following:
DOMNode* XMLUtils::getDOMNodeFromXPath( const sfly::string& xpath ) {
XercesDOMSupport xds;
XalanNode *contextNode;
XercesParserLiaison theParserLiaison;
auto_ptr<XPathEvaluator> theEvaluator( new XPathEvaluator() );
XalanDocument *theDoc = theParserLiaison.createDocument( parser->getDocument());
XalanDocumentPrefixResolver thePrefixResolver( theDoc );
XalanDOMString dsPath( xpath.GetData(), xpath.GetLength() );
const XalanDOMChar *path = dsPath.c_str();
contextNode = theEvaluator->selectSingleNode( xds, theDoc, path, thePrefixResolver );
return XalanNodeToDOMNode( contextNode );
}
Thank you very much in advance!
Best Regards,
Ivan
