[dom4j-user] Urgh, more xpath!

[David Hooker]

Title: Message

Why does this work:

 

            Node node = doc.selectSingleNode(globalExprString);

when this does not:

 

            XPath expr = DocumentHelper.createXPath(globalExprString);
            Node node = expr.selectSingleNode(doc);

???

 

Is there something in some docs or comments or web sites or faq's somewhere that I missed that explains how in general to do xpath with dom4j?
