can't search a xpath which contains "node"

```
What steps will reproduce the problem?
1. Get a dom object
2. Use a xpath which contains "node" to find a node.
xpath.find("//node[@name='xxx']", element)
3. Get an Exception:
*** XPathParseError: Syntax error:
//node
------^

Why I can't use a xpath contains "node"?

```
