XPATH: position()

2005-04-15 06:43

Is it possible to use the position() function in the description of a field to determine wich row i'm currently reading in my xml?

 

It seems like i can only use the XPATH abreviated syntax.

 

Thx in advance

 I think it's not possible to use that function...

I have an xml document with this structure:

<form>

  <questions>

     <question>...</question>

 

     <question>...</question>

     <question>...</question>

  ...

 

</form>

And I'm giving it to my template with XPath /form/questions/question

Then in my template I have a field $F{position} which value is 

<fieldDescription>position()</fieldDescription>

Finally I print that field inside my detail band.

It seems that it actually try to use the field $F{posisition}, just that it prints a fix value in every iteration: -1.

Can anyone confirm that this is actually a bug?

position() will not work because field XPath expressions are evaluated in the context of the current node (i.e. one of the question nodes), and not in the context of the /form/questions/question node list.

Wouldn't $V{REPORT_COUNT} do?
