AX 2012 : Remove an XML node through X++

Following code snippet may help you to remove an XML node from an XML message string.

private str removeXMLTag(str xml)

{

    XmlDocument         doc = new XmlDocument();

    XmlElement          nodeScript;

    XmlNode             parentNode, childNode;

    XmlNodeList         xmlScriptList,

                        parentNodeList,

                        childNodeList;

    int                 i,j;

    doc.loadXml(xml);

    // Get the root element and its child nodes

    nodeScript = doc.getNamedElement("SalesOrder");

    xmlScriptList = nodeScript.childNodes();

    for(i=0; i < xmlScriptList.length(); i++)

    {

        parentNode = xmlScriptList.item(i);

        childNodeList = parentNode.childNodes();

        for (j=0; j < childNodeList.length(); j++)

        {

            childNode = childNodeList.item(j);

            if (childNode.selectSingleNode("Notes"))

            {

                parentNode.removeChild(childNode);

            }

        }

    }

    return doc.outerXml();

}

This will remove DocuRef node along with its child nodes.
