DOM vs SAX for XML Parsing

I had an initial version of this script using DOM method for XML parsing. Here are some basic stats comparing it to this version that uses a SAX parser instead.

Sample File:

17 hosts, 238MB

DOM

Execution Time: 435.21s user 5.99s system 98% cpu 7:27.24 total RAM Usage: ~3GB

SAX

Execution Time: 41.04s user 1.32s system 97% cpu 43.278 total RAM Usage: maxed out at 253.4MB
