Rails - Jun 2009 - how can i get attribute values from xml using libxml

Hi ,
i have xml document like this
<?xml version="1.0" encoding="ISO-8859-9"?>
<Root><Stk Category="601" Group="60101"
Brand="001">....................

then i have to use Category attribute but reader class couldnt
recognize attributes

when i use these codes below for testing;

		while reader.read

		puts reader.node_type
		end

it shows only 1 and 15 values which means
XML_READER_TYPE_ELEMENT                 => 1
XML_READER_TYPE_END_ELEMENT             => 15

how can i get attribute values?

 i tried another method
doc = reader.expand
doc.find(''//Root/Stk/[Category=''601'']'')
but it also didnt work

try doc.find(''//Root/Stk[@Category="601"]'')

Thanks a lot Simon , it worked ,
can we double this filter method like category="601" and
brand="15" at
the same time
