Hi Group,
Can somebody point out why this xpath is not working. I have also declared
a namespacemanager but still it gives error
-----Namespace Manager or XsltContext needed. This query has a prefix,
variable, or user-defined function.
I can fetch what I want by using xml.schema namespace but I don't want to
use xml.schema class for this coz this xpath simplifies my work to great
deal.
The code snippet looks like this ---
XmlDocument xdSchemaDocument = new XmlDocument();
xdSchemaDocument.Load("D:\\BackupJIB\\feb21\\jib.xsd");
XmlNamespaceManager xnmNamespaceForxsdPrefix = new
XmlNamespaceManager(xdSchemaDocument.NameTable);
xnmNamespaceForxsdPrefix.AddNamespace("xsd","http://www.w3.org/2001/XMLSchem
a");
XmlNode xnDataTypeNodeFromXSD
xdSchemaDocument.SelectSingleNode("//xsd:element[@name=\"ThreadId\"]");
----
I am just trying to fetch the element tag which has attribute name --
ThreadId

You only miss 1 parameters in your selectSingleNode() function
When using xmlNameSpace in Xpath query, you must set the
XmlNamespaceManager as the second parameter of selectSingleNode()
Ex:
XmlNode xnDataTypeNodeFromXSD = xdSchemaDocument.SelectSingleNode
("//xsd:element[@name=\"ThreadId\"]",xnmNamespaceForxsdPrefix);
PS: Dont forget to set the namespace in the XML document itself Ie:
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
