Try this as I don’t know how to do what you’re trying to do using that simpler
code:
Map m = new HashMap();
m.put(“html”, “http://www.w3.org/1999/xhtml“);
Xpath xpath = DocumentHelper.createXPath(“//html:meta”);
xpath.setNamespaceURIs(m);
Element metaElem = (Element) xpath.selectSingleNode(document);
I think this will retrieve the first “meta” node.

Well it’s an HTML document. It does have an xmlns declaration, although it’s
been a while since I’ve done any XML so I don’t remember exactly what that
does. But the elements themselves, like <meta> don’t have any namespace
prefixed to them.
The xmlns declaration is:
<html xmlns="http://www.w3.org/1999/xhtml"; lang="fr">
Thanks for your help

Hello,
I’m having an issue with a very simple Xpath expression. I don’t quite
understand why this fails. Probably missing something obvious. This is just a
simple example:
SAXReader r = new SAXReader();
try {
Document document = r.read(new File("c:\\file.xml"));
Element metaEle = (Element) document.selectSingleNode("//meta");
} catch (Exception e) {
e.printStackTrace();
}
Now « file.xml » definitely has a meta element but this always returns null.
I’ve tried also selectNodes to see if that makes any difference. I tried with a
bunch of other tags but they all fail unless if I put in the root tag. If I’m
not mistaken though “//meta” should return all meta elements in the document???
Thanks for any help with this.
Matt
