Implementing getparent Pseudo Selector extension

[datatooldev]

Hi James,
I am trying to implement a get parent extension similar to the JavaScript code below:

    jQuery.expr[":"].getParent = function (node, index, prop, nodes) {
        return jQuery(node).parent(); 
    };

I have implemented a PseudoSelectorChild which overwrites ChildMathes method
public override IEnumerable ChildMatches(IDomContainer element)
{
yield return element.ParentNode;
}
Unfortunately, this method never gets called, probably, because TraversalType is set to Filter. Is there any way to implement that extension?

Thank you,
Vladimir
