[plt-scheme] xml-parsing

Hello List,

  I am trying to parse an xml fragment. I am noting that it seems all the
provisions from the xml library require the document to be a full xml
document with a root tag. Is it not possible to parse fragments with the
current library? My desired function would be as such:

given a STDIN
this is a <a href="http://www.test.org">test</a>

a call to 
(xml->xexpr (my-desired-function))

produces
("this is a " (a ((href "http://www.test.org")) "test"))

When (define my-desired-function read-xml/element) I get an error
complaining about a missing root tag :-\

Thank you,
-mike
