The heap is not one big undifferentiated bucket of storage. It contains different sections, or generations, that are used to store different scopes of variables. Simply increasing the overall heap may not have any effect on the amount of storage for this variable. Do you have specified sizes for the young and perm generations? If not, you might want to set them. All that said, you might also want to switch to SAX parsing if you're working with extremely large XML files. SAX parsing is (in my opinion) a lot more programming work, but it's designed to let you solve this sort of problem.
