selectNode() on on-IE browsers

[bigduke]

I have been learning about the XML family from W3Schools because thats the only place that makes some sense.

Their examples for XPath used selectNode for choosing nodes conditionally. Is there such a method for some native js xml object as well which could be used for other browsers as well? The next step is to use this with XSLT, but what if I were to use the feature for dynamic filtering of data such as you have one XML file, some filter interface attached to js filtering command and maybe some XSLT to format and display the "redued" results.

Any clues / leads ?
