Sorry i wasn't clear about that. I'd like everything inside of linktext to go inside of xref.

<xref><keyword conref="ds"/> support for IPv6 addresses</xref>
[download]

I also didn't mention there might be other elements midway.

<linktext><keyword conref="ds"/> support for <b>IPv6</b> addresses</li
+nktext>
[download]

So I need to iterate through the @children array and handle each child, which is either text or an element.

thanks, will try these other suggestions.
