XML > JSON: How do I 'intercept' processing of a specific node?

[blaasvaer]

I need to strip a node for HTML tags ... how would I go about doing that? I've spent a couple of hours trying to 'figure' out the docs and trying all sorts of things by basically guessing, as the docs are clearly written by the same guy who wrote the lib. But I have had absolutely no success in using any of that information.

I have a node that looks like this:

<text>Ya da <grouptext>Ga Ba</grouptext>.</text>

I need to strip the text node for grouptext nodes (leaving out that 'level').

Now, from the docs I'm getting the impression I can add a custom function to the config:

var xmljs_options = {
	compact: true,
	spaces: 2,
	textFn: function ( value, parentElement  ) {
		// How can I access the text node on the parent element
		// and modify the value?
		if ( parentElement.nodeName? === 'text') {
			// strip tags and return modified value
		}
	}
};
