Subject Re: [JXPATH] Prefix on jxpath sentence when read DOM
Date Tue, 15 Feb 2005 21:28:39 GMT
ijorge,
 
I have been getting a bunch of requests for a change in this area.  The problem is that I
currently don't know what change to make without breaking the conformance to the XPath specification.
 See http://issues.apache.org/bugzilla/show_bug.cgi?id=32360
 
Please advise,
 
- Dmitri

Iīm a question about the behavior of jxpath when read DOM with a 
sentence without prefix. If I have this sentence:

context.getValue("$root/example1[@name="aa"]/example2");

This sentence donīt works because "example2" doesnīt have a prefix. My 
jxpath code is generated automatically and I donīt know the prefix when 
this code is generated.

I see these solutions:
1) not to change anything because prefix are necessary.
2) jxpath searches a empty prefix in the registered namespaces.
3) jxpath searches the default namespace in the ancestors.
4) 3) and 2).

I have changed the class 
java/org/apache/commons/jxpath/ri/axes/SimplePathInterpreter.java, the 
method getNodeIterator() and this change (solution 2) resolve my 
problem. I comment on this situation because I think current behavior 
should be changed.
