Hallo,
i have a problem with this C++ SourceCode. I want to do a XPath Query
on the XSD-Document on the end of this posting. I have to search the
Attribute "bg:bin" in the XSD-Document, but i did not know the exact
position (this can change from case to case). The Query "//*[@bg:bin]"
returns everytime 0. The Query "//*[@value]" returns the searched
XmlElement "<xs:maxLength>". I dont understand why. Is it posible that
i can not search a Attribute whith an different namespace as his
XmlElement?

Can somebody help me whith my problem?


XmlDocument *XmlSnippet = new XmlDocument(); 
XmlSnippet->Load("Datei1.xsd"); // load XSD-File
XmlElement *root = XmlSnippet->DocumentElement;


// a new  NamespaceManager for "xs" 
XmlNamespaceManager* nsmgr1 = new
XmlNamespaceManager(XmlSnippet->NameTable);
nsmgr1->AddNamespace(S"xs", S"http://www.w3.org/2001/XMLSchema");


// a new NamespaceManager for "bg" 
XmlNamespaceManager* nsmgr2 = new XmlNamespaceManager(new
NameTable());
nsmgr2->AddNamespace(S"bg", S"namespace\namespace_bg.xsd");


XmlNode *node1;
	
// whith this XPath-Query i can find the attribute "value" 
// node1 = root->SelectSingleNode("//*[@name]",nsmgr1); 
	
// this XPath Query returns everytime 0, but why?
node1 = root->SelectSingleNode("//*[@bg:bin]",nsmgr2);
