Re: [jxpath] problem with predicates

hello Dmitri,

Joern,

An attribute pointer (like many other kinds of pointers) holds onto the
node it represents and therefore may return a stale value.  To get the
fresh value you need to do something like this:
Object newValue = context.getValue(pointer.asPath());

I hope this helps.
yes and thanks for the quick answer. this clarifies some problems i had. 
actually my testcase wasn't correct which lead to the problems but 
nevertheless your answer is very helpfull for our understanding.

best,

hello,

i've got a problem evaluating predicates when used in conjunction
with 
relative contexts.

here the xml-input i'm using:
<people>
    <person name="Name1"></person>
    <person name="Name2"></person>
    <person name="Name3"></person>
    <person name="Name4"></person>
    <new name="NameX"></new>
</people>
here's the code:

//document is a DOM containing the above xml
JXPathContext rootContext = JXPathContext.newContext(document);
//the xpath must be evaluated relative to pointer
Pointer pointer = rootContext.getPointer("/people/new/@name");
JXPathContext relativeContext =
      rootContext.getRelativeContext(this.pointer);
//ok 

assertTrue(relativeContext.getPointer("not(//person/@name=.)").getValue().toString().equals("true"));

//fails
this.pointer.setValue("Name1"); 

assertTrue(relativeContext.getPointer("not(//person/@name=.)").getValue().toString().equals("false"));

i've tried this and that but with no success. can someone shed some 
light on this or teach me what i'm doing wrong?

thanks,

Joern
