appendChild help?

[Paul / U. <pa...@tr...>]

I'm using Php.XPath Version 2.1 and I'm having some trouble understanding what to pass into appendChild as the node.

Could someone give me a simple example of appending a child to a node.

e.g.

file contents are <root></root>
$xml = new XPath("$filename");
$xml->appendData("/root[1]", "blah" );

What do I put in instead of "blah" to add a node called blah?
