new to xml / xsl

[Tinarandel]

ok im creating a dummy webservice using c# im familiar with c# and the hard-coding side of this project but xml and xsl come in as a bit of a haze. now i have created an XML file to contain all details needed basically my web service has got to grab the data needed do stuff with it and create a new xml file to be passed around a network. I believe my xml to be correct but i am having trouble even performing simple tasks with xsl. I have followed tutorials as such but cannot get this to work could someone please take a look and tell me if i am doing this correctly.
