Need to parse java string with XML data

[Walter Vaughan]

Does anyone know of some good java SAX or DOM "Hello World" type tutorial sites? 
I have xml data in a java string (NOT A FILE) that I want to parse and use in 
ofBiz, and every example I've looked at looks like it's either severe overkill 
or way underkill (character by character).

My problem also is finding example code where the data is a string variable 
inside java and is in a <name=value> style xml rather than <name>value</name> xml.
