list children of element (jdom)

[James Howerton]

What do I need to learn to stop on a certain element which this class can do. But I would like to work with the children of the element is finds?

[Paul Clapham]

Well, if your question is "Why isn't the processSelectedElement method being called?" then the answer is, it's because the comparison in line 94 always returns false.

It looks a bit suspicious to me, comparing the value of an attribute to a variable whose name is "attrName". So maybe there's some confusion there? I can't tell just from the code.
