Dr. Strangelove (or: How I Learned to Stop Worrying and LoveXML)

[Bill Marriott]

The problem with XML is that people can do any old thing they want with it. 
While the RULES are ridiculously strict, the implementations can drive you 
nuts. For example, look at the cookies.plist file on a Mac. It has a really 
wacky setup that I think makes it all but impossible to parse with the 
RevXML library without "walking" through it. Its something like:

<person>
  <attributes>
    <field>Name</field>
    <value>Bill</value>
    <field>EyeColor</field>
    <value>Blue</value>
  </attributes>
</person>

Whereas the Rev library seems to make it easier to do something like:

<person name="Bill" eyecolor="blue" />

To be honest, I usually poke around in Sarah's stack and then figure out 
which function(s) I need through trial and error. It's just harder for me to 
"visualize" what I want to accomplish with XML.

I can say that once you figure out what two or three commands you need to 
use to parse an XML file, it's way faster than using chunk expressions or 
some other method.
