javascript ext. element acessing xpath results?

[Liedl Markus <Ma...@temic-sp.com>]

hi there,

is there anybody using a javascript extension element that acesses xpath results of the  source xml document?

I'm aiming at extensions like
<my-ext:join sep=", "  select="person/@name"/>

I'v used o.a.x.XPathAPI.selectNodeIterator(), to realise the javascript join() function, like sample/applyXPath is doing, but obviously i'm not understanding, that javascript extension code that is called during the transformation does not have the possibilities it has outside. Any help?

thanks,
markus
