If you use JSTL instead of XTags (which indeed influenced the design of
JSTL's XML-manipulation tags), you can retrieve a document from the
request scope using the expression language. For instance, if the
document is stored as a string of XML text, you could write
<x:parse var="parsed" xmlText="${request.myXmlDocument}"/>
If the data is stored as a DOM, you can jump right in and point to the
document directly. E.g., --
<x:out value="$request:myXmlDocument/root//child[2]"/>
JSTL is available from the same jakarta.apache.org/taglibs site as XTags.
