Xindice manipulation

[David Cahill]

I'm attempting to adapt the example1.java program that accompanys Xindice to
manipulate my own "handbook.xml" file which I placed within the addressbook
collection in Xindice.  I'm attempting to access the "Handbook" element &
match the value contained within the "email" attribute which itself is
contained within the "departmental-office" attibute.  When i run this
program it compiles but I'm not getting any output. Can you see where I'm
going wrong?

Cheers,

David
