JAXP, I need Help

Dear incharge,
I am in real need, please suggest me some place where I can read about javax.xml.transform packages. I can use it but I get stuck here and there. I posted a query here but I did not get any response. Please take time out for me.
Please do.

I really recommend the Orielly XML in a nut shell book and here are some links I found useful as well
