But I can't find any methods on Element for iterating sequentially on them like this?

Element is a subclass of Node, so your code should work just fine?

Edit: the reason your code is not working is because you can't get the text contained in an element by calling getNodeValue() on it - that always returns null.
The text you want is in the child of that element node as a text node, so what you want to do instead is:

code:

String value = node.getFirstChild().getNodeValue();

(and possibly check that the child actually exists and is of Node.TEXT_NODE type)

ugh, i'm just going to write that little detail off as a typo then. Thanks

What was meant was probably: don't use raw arrays, instead use the Collections framework (List/Set/etc), which is good advice for people just starting out with Java.

code:

run_once = false;
while (<condition> AND run_once) {
    ... stuff ...
    run_once = true;
}

I think you meant:

code:

run_once = true;
while (<condition> OR run_once) {
    ... stuff ...
    run_once = false;
}
