Is it possible to merge two (or more) xpath2 dataset

[mauricio]

hello, I'm using iReport 4.1.3

I have one report which data source is an xml file, so I'm using xpath2

 

I'm interested on getting charts about the "request" node as total (count, state based on request properties inside each one)

 

I can define 3 different datasets for each group of requests and get usefull info for each one, say:

-root/requests

-root/particular/requests

-root/particular/more_particular/requests

 

but I need now some way to merge all request and get info from them, as if I were looking a complete requests array, something as

 

total/requests = ( root/requests + root/particular/requests + root/particular/more_particular/requests )

 

each request has an id, no repeated data, all request have similar structure inside

 

hope someone can help, thanks in advance

 

xml file is structured similar to this

<root>

<particular>

<requets>

<request>

<request>

<request>

</requests>

<more_particular>

<requets>

<request>

<request>

</requests>

</more_particular>

</particular>

<requets>

<request>

<request>

</requests>

</root>

ok, I generated a fourth dataset with the xpath

 

//root/*/requets/request

 

with this I was able to perform some count and stuff

 

hope its usefull for someone else
