Use a StAX parser instead of a DOM parser. StAX will let you look at the elements in order, but without having to read the entire thing into memory at once and then navigate the hierarchy.
I can't remember if there's a StAX parser in Android (it was included as part of 1.4 or Java 5, I can't remember which), but there's a reference implementation from BEA floating out on the Web someplace, should be a snap to grab it and include it as a library (worst case).
