Could someone tell me what has to be changed to get the element name and text of my targetElement?

I just get

internal frame openFrameCount= 1
start obj() type= guide
cmaj
name: null value: null
name: null value: null
name: null value: null
cmaj
name: null value: null
name: null value: null
name: null value: null

I validated my xml with a DTD. Will that make it easier to solve my little problem finding data?

Well I got the siblings I need but need a good method to produce the text node. Is there a standard method for this?
