Subject Re: xpath queries with node names consisting of numbers?
Date Mon, 04 Aug 2008 09:34:19 GMT
The following statements are the most efficient:
//_x0031_234
//*[fn:name() = '1234']

Note that  fn:name() is only supported since Jackrabbit 1.4 and will
just not match (no exception thrown) if it is not supported (Jackrabbit
1.3.*)...
