How to canonicalize an XML Document subsets

[Martin]

Hi,

I canonicalize document subset and result is different
from w3c.org examples. Do you know where is the problem?

thanks Martin

String xPath="(//. | //@* | //namespace::*)[self::mss:Parent or
(parent::Parent and not(self::Child)) or self::ns1:GrandChild or
parent::ns1:GrandChild]";

XmlNamespaceManager nsmgr=new
XmlNamespaceManager(message.NameTable);
nsmgr.AddNamespace("ns1","http://example.org/ns1");
XmlNodeList nodeList=message.SelectNodes(xPath,nsmgr);

XmlDsigC14NTransform tr=new XmlDsigC14NTransform();
tr.LoadInput(nodeList);
Stream res=(Stream)tr.GetOutput();

INPUT DOCUMENT:
<GrandParent xml:lang="en" xml:space="default">
<Parent xml:foo="bar" xml:fool="barbar">
<Child xml:foo="barbarossa" xml:lang="ge">
<GrandChild xml:space="preserve"/>
</Child>
</Parent>
</GrandParent>

MY RESULT:
<Parent xml:lang="en" xml:space="default" xml:foo="bar" xml:fool="barbar">
<GrandChild xml:foo="barbarossa" xml:lang="ge"
xml:space="preserve"></GrandChild>
</Parent>

CORRECT RESULT :
<Parent xml:foo="bar" xml:fool="barbar" xml:lang="en" xml:space="default">
<GrandChild xml:foo="barbarossa" xml:fool="barbar" xml:lang="ge"
xml:space="preserve"></GrandChild>
</Parent>
