Funny thing is, my lead engineer said the same thing... Mostly this was an experiment to gain a better understanding of DOM outside of HTML. This is about as exciting as a SAX parser when it comes to speed (<5sec in safari for 20K lines, slightly longer in FireFox, and noticeably longer in Chrome), though it is fairly efficient, and gives me exactly the results I was wanting to see. There are some practical applications.
Realizing that there is only so much memory out there more efficiency is what I am going for, so any input on this script is helpful. I have approached it this way because I get XML and DOM, and I am getting decent at jQuery. Thus this method was in my range of current understanding. JSON is something that I am just now becoming more familiar with.
