I'm having trouble with xpath's returning valid results in dom4j. My co-worker was trying to select a div in an xhtml
file based on a class attributes and was getting any results, even though he could get results with the same XPath in
jedit (using saxon) and it worked fine.
I told him about the namespace problem and added the code -- as Edwin has suggested in the past -- to add a map of
namespaces, with just "" mapped to "http://www.w3.org/1999/xhtml";. This works for selecting unqualified elements; i.e.
without the [EMAIL PROTECTED]'foo'] predicate. (Well, we struggled for a while with it working on my machine but not on his and
discovered that he had jaxen-1.1-beta-6 and I had beta-4... so beta-6 apparently introduced a bug!). However, I have
been trying for hours to get "//[EMAIL PROTECTED]'content_left']" to work. I'll paste the code/html below.
Really hoping someone's listening and can help here... Edwin, my savior, you
out there?
b
code:
SAXReader reader = new SAXReader();
Document document = reader.read(new File("findings.html"));
XPath xp = DocumentFactory.getInstance().createXPath("//[EMAIL
PROTECTED]'content_left']");
Map ns = new HashMap();
ns.put("","http://www.w3.org/1999/xhtml";);
xp.setNamespaceURIs(ns);
List nodes = xp.selectNodes(document.getRootElement());
