Im sure this easy but Im not sure !

I want to select nodes from an XML (RDF) but probably understand the syntax
for including the containing elements

For example, If I use

       var nodes = xmldoc.selectNodes("//RDF:Description[@role:area='US']");

 I get valid results for the US apart from the fact I havent generated any
containing elements especially the root node so I assume I need something
like

      var nodes =
xmldoc.selectNodes("//RDF:Description[@role:area='US']/ancestor-or-self::*")
;

or

       var nodes =
xmldoc.selectNodes("//ancestor-or-self::RDF:Description[@role:area='US']");

and then dump it using

    for (i=0;i<nodes.length;i++ )
     {
         Response.write(nodes.nextNode().xml)
     }

but all my attempts generate token errors in my asp page

Expected token 'eof' found ':'.

Any ideas what this refers to ?
