Hi All,

Please could someone advise me on how to populate an XML Node parameter on a secondary data source webservice call. The simplified code below errors with "The left-hand side of an assignment must be a variable, property or indexer" I understand the error but i am now confused as to how i am going to populate this non simple data type webservice parameter.

// Create new XML Document.
System.Xml.XmlDataDocument xmlDataDoc = new System.Xml.XmlDataDocument();

// Populate document.
xmlDataDoc.LoadXml("<HELP><Scott>Test</Scott></HELP>");

// Create Node.
System.Xml.XmlNode xmlNodeParam = xmlDataDoc.FirstChild;

// Assign Node to webservice parameter.
thisXDocument.GetDOM("BuildTaskPane").selectSingleNode("//*[local-name()='xmlNodeData']") = xmlNodeParam;

xmlNodeData is the name of secondary data source queryField.
Any pointers would be greatly appreciated.

Many thanks in advance, Scott

Hi ScottAtRVC,
I dont know whether i understood your problem in full or not, but let me put your question in my words

before answering it.

You want to submit XML as an Input parameter to a webservice dataconnection.
If my understanding is correct here is the solution:

1. If webservice wants xml as a string you can pass your xml as below

thisXDocument.GetDOM("BuildTaskPane").selectSingleNode("//*[local-name()='xmlNodeData']").text = "<HELP><Scott>Test</Scott></HELP>";

2. If webservice wants xml as a child to your "xmlNodeData" node then you need to do the following

//create a dom with your XML
string sXml = "<HELP><Scott>Test</Scott></HELP>" ;
IXMLDOMDocument oXml = thisXDocument.CreateDOM();
oXml.async = false;
oXml.loadXML(sXml);
//Append your dom to the Node the selected Node
thisXDocument.GetDOM("BuildTaskPane").selectSingleNode("//*[local-name()='xmlNodeData']").appendChild(oXml)


Hope this Helps!

Agni. Thanks for your reply and time. This worked a treat. The only difference was i needed to assign a Node to the parameter and not a document. So the final code was;

//create a dom with your XML
string sXml = "<HELP><Scott>Test</Scott></HELP>" ;

IXMLDOMDocument oXml = thisXDocument.CreateDOM();
oXml.async = false;
oXml.loadXML(sXml);

IXMLDOMNode oNode = oXml.createNode(System.Xml.XmlNodeType.Element, "Data", string.Empty);
oNode = oXml.documentElement;

//Append your dom to the Node the selected Node
thisXDocument.GetDOM("BuildTaskPane").selectSingleNode("//*[local-name()='xmlnodeDOM']").appendChild(oNode);

Once again, many thanks for your time.
kind regards
Scott
