Seems like I overcomplicated that one

Apparently just attr.nodeValue = "14" should work.

Changing attribute value for an existing element

ACrush — Tue, 20 Jan 2009 16:51:03 GMT

I found some unexpected behaviour while developing my InfoPath 2003 compatible form template with C#.
The problem is, I cannot change an attribute value on an existing element with the following code:

Initial element
<my:Employee xmlns:my="..." my:ID="" my:FirstName="Jane" my:LastName="Doe">Jane Doe</my:Employee>

node = thisXDocument.selectSingleNode("my:Employee"); // OK
attr = node.attributes.getNamedItem("my:ID"); // OK
node.attributes.setNamedItem(attr).nodeValue = "14"; // COM Exception

The debugger shows COM exceptions like E_FAIL or 0x80043001 which are not informative.
The same code works with temporary elements:

node = thisXDocument.DOM.createNode("my:Employee"); // OK
node.attributes.setNamedItem(thisXDocument.DOM.createAttribute("my:ID")).nodeValue="14"; // OK

Result:
<my:Employee my:ID="" ></my:Employee> Assistance / advice appreciated.
