Question

I’m creating a node programmatically, however one of the attributes comes out differently than what I specified in the code:

                XmlNode xResource = docXMLFile.CreateNode(XmlNodeType.Element, "resource", docXMLFile.DocumentElement.NamespaceURI);
                XmlAttribute xRefIdentifier = docXMLFile.CreateAttribute("identifier");
                XmlAttribute xRefADLCP = docXMLFile.CreateAttribute("adlcp:scormtype");
                XmlAttribute xRefHREF = docXMLFile.CreateAttribute("href");
                XmlAttribute xRefType = docXMLFile.CreateAttribute("type");
                xRefIdentifier.Value = "RES-" + strRes;
                xRefADLCP.Value = "sco";
                xRefHREF.Value = dataRow["launch_url"].ToString().ToLower();
                xRefType.Value = "webcontent";

                xResource.Attributes.Append(xRefIdentifier);
                xResource.Attributes.Append(xRefADLCP);
                xResource.Attributes.Append(xRefHREF);
                xResource.Attributes.Append(xRefType);

This ends up creating a line like the following. Note that ‘adlcp:scormtype’ has morphed into ‘scormtype’ which is not what I specified. Any ideas how to get it to show what I put in the CreateAttribute?

 <resource identifier="RES-CDA68F64B849460B93BF2840A9487358" scormtype="sco" href="start.html" type="webcontent" />

This is probably expected behavior of this override CreateAttribute combined with saving the document:

The NamespaceURI remains empty unless the prefix is a recognized built-in prefix such as xmlns. In this case NamespaceURI has a value of http://www.w3.org/2000/xmlns/.

Use another override XmlDocument.CreateAttribute to specify namespace and prefix:

XmlAttribute xRefADLCP = docXMLFile.CreateAttribute(
     "adlcp","scormtype", "correct-namespace-here");
