Well, after trying it for more than four hours, it's making me feel
stupid...again...
I thought I could ask around for help again.
I have the usual code for iterating through the resources (copied below),
then I clean the String from the resource as commented in previous messages
in this same thread, and the 'initEquipmentTypes' method gets it, where I
want to manipulate the produced String and create the DOM document. The
String reaches the method, I can print it and I see everything is there, but
for some reason the parse fails! After parsing it, the document only has the
root element I hard coded, but nothing from the String I got from the DB :-(
I thought it could be something with the encoding, I browsed the list
archives and trying at least half dozen solutions to that problem with no
luck either. This is absolutely frustrating...hope someone could point me in
the right direction. Thanks.
Josema.
