Easy way to create an XmlNode with specific xpath?

[Michael Bray]

Is there an easy way to create an XmlNode with a specific XPath, creating
nodes along the way if necessary? For example, if I start with an
XmlDocument xmlDoc with contents:

<Test>
<Node1>Blah</Node1>
</Test>

and I want to store information in the XPath /Test/Node2/SubNode/@attr to
result in:

<Test>
<Node1>Blah</Node1>
<Node2>
<SubNode attr="attrtext" />
</Node2>
</Test>

is there an easy one-liner that will create this node so that I can say the
following??

newNode.InnerText = "attrtext";

Or do I have to code it into a function (I don't need to know how to code
this function - I'm just wondering if there's something I'm missing.)

Thanks!!
