new to XML and am very stuck!

[hotpot]

Hi all,
Im new to all this XML stuff
below I have some code I am just starting to write and I want to view the output as I build it.so I have a function documentToString that converts the doc to a String . However when I run it I dont get any output- just a white box appears.
I would be grateful for any feedback

also another question I have is how does one input data between the 2 elements
<element> how do I put data in here <\element>
thanks
