[xsl] method of converting xml string to xml nodes

["Majirus FANSI" <jmfansi@xxxxxxxxxxx>]

Hi all,
Should anyone know a trick to convert  xml string to xml nodes?
In fact,for my application  i provide a textarea form to a visitor for 
keyboarding an XUpdate document. I need to treat this field within my 
stylesheet as a xml document, not only as a string.
I browsed xsl list archives and then remarked that this question appeared on 
Thu, 7 Nov 2002. according to these  archives, the only way to solve the 
problem is to write an extension function.
should anyone has such extension?
any suggestion is welcome.

thanks in advance,
Regards
