I found the answer myself.
Apparently, the default namespace does not work with the namespace
manager, so you have to give the default name space a name, for
example ns.
Then your xpath questions work, if you write them like this:
XmlNamespaceManager ns =3D new
XmlNamespaceManager(pg1.NameTable);
ns.AddNamespace("ns", "
http://schemas.microsoft.com/sqlserver/ reporting/2005/01/reportdefinition");
ns.AddNamespace("rd", "
http://schemas.microsoft.com/SQLServer/ reporting/reportdesigner");
string source =3D "//ns:Report/ns:Body/ns:ReportItems/
ns:Rectangle[@Name=3D'rctPage']/ns:ReportItems";
MessageBox.Show(pg1.SelectSingleNode(source, ns).InnerXml);
Notice that you should not add the namespace identifier for
attributes, see @Name above. Very strange, but it works.
