I retrieve my XML from an XML database (XStreamDB), and successfully feed it to dom4j to get back an Element (or a Document) representing the contents of the xml document.
Now, I'm trying to use dom4j to process the contents of the Document to pull out some values (and to insert/change some values).
I'm doing something like this (I've simplified the XPath to show something that should have at least one value in my document):
String xmlContent = (some magical process to get it from the database)
Document myDocument = reader.read( new InputSource( new StringReader( xmlContent ) ) ).getDocument();
XPath xpath = DocumentHelper.createXPath( "//identifier" );
Node identifierNode = xpath.selectSingleNode( myDocument );
List matchingNodes = xpath.selectNodes( myDocument );
System.out.println( identifierNode );
System.out.println( matchingNodes );
All I get for identifierNode is null, and matchingNodes is an empty List.
My documents have at least one "identifier" element, so I'm confused why dom4j isn't finding either.
If I open up the xpath selector to be something like "//string" (there are dozens of "string" elements in each document), I still get null for the selectSingleNode(), and an empty List for selectNodes().
Any ideas, tips or hints would be greatly appreciated!
