Recursion Examples

Hi,

I was hoping somebody could point me to an example of buidling a tree down
to n nodes. I have xml that looks like this:

<version>
	<module>
		<id>0</id>
		<name>foo</name>
		<parentid>root</parentid>
	</module>
	<module>
		<id>1</id>
		<name>foo</name>
		<parentid>0</parentid>
	</module>
	<module>
		<id>2</id>
		<name>foo</name>
		<parentid>1</parentid>
	</module>
	<module>
		<id>3</id>
		<name>foo</name>
		<parentid>2</parentid>
	</module>
</version>

There could be multiple module elements each with different parentid and I
need to be able to build a tree that represents the data. I'm sure somebody
has done this before.

Pointers? Links? Thoughts?

Thanks,

Jon
