Hi all, we are trying to make some variable manipulation in a bpel file with xpath but I can not find what I do wrong...
This is the wsdl of the service I invoke (airbus.wsdl): <?xml version="1.0" encoding="UTF-8"?> <wsdl:definitions xmlns:ns0="http://www.a-ware.org/airbus/xsd"; xmlns:tns="http://www.a-ware.org/airbus/xsd";

My final goal is to use counter as an index: /wsdl:frequencies/xsd:frequency[$counter] But this obviously doesn't work either. What am I doing wrong? I have tried every think but it seems that the notation "[]" gets always ignored by ode. I am using apache-ode-jbi-1.0-RC4-incubating-SNAPSHOT.zip which I built from the SVN trunk at 2007-05-24, in service mix 3.2-incubating-SNAPSHOT. Thank you for your help, Luca
