XmlMassUpdate Multiple Values (MSBuild Community Tasks)

Question

Say you have a config file with the following settings:

<someNode>
    <node>value A</node>
    <node>value B</node>
    <node>value C</node>     
</someNode>

For the life of me, I can't figure out how to get XmlMassUpdate to inject the following:

<someNode>
    <node>value 1</node>
    <node>value 2</node>
    <node>value 3</node>     
</someNode>

The result looks like this:

<someNode>
    <node>value 1</node>
    <node>value B</node>
    <node>value C</node>  
</someNode>

What I'm shooting for is:

<someNode>
    <node>value A</node>
    <node>value B</node>
    <node>value C</node>
    <node>value 1</node>
    <node>value 2</node>
    <node>value 3</node>    
</someNode>

EDIT: I found a temporary solution (see below)... still interested in something better, though.

<someNode>
    <node xmu:key="id" id="1">value A</node>
    <node xmu:key="id" id="2">value B</node>
    <node xmu:key="id" id="3">value C</node>
</someNode>

Answer 1

The answer is to apply a unique attribute to the element and use that as the xmu:key (see EDIT above).
