    I have the following xml:

    [color=blue:67475ee949]<ns0:Sample xmlns:ns0=\”http://BizTalkOrch.InPutSchema\”>
    <Body>
    <AnyThing>AnyThing_0</AnyThing>
    </Body>
    </ns0:Sample>[/color:67475ee949]

    This message is assigned to message variable InMsg.
    I have a variable called xmlDoc of type System.xml.xmldocument
    I have another message of type System.xml.xmldocument called OutMsg

    I am using xPath to extract some of InMsg message details:
    my xpath expression is:

    [color=darkred:67475ee949]xDoc = new System.Xml.XmlDocument();
    xDoc= xpath(InMsg, \”//*[local-name()=’Body’][0]\”);
    OutMsg=xDoc;[/color:67475ee949]

    When I execute this and check it the Debug mode tracked events:

    I get the following error:

    [color=red:67475ee949]Microsoft.XLANGs.Core.NullPartException: The part ‘part’ of message ‘OutMsg’ contained a null value at the end of the construct block[/color:67475ee949].

    I feel something is wrong in my xPath statment. Please help If you can suggest some thing better.
