A better version of 'Load-XML:
Load-XML: function [
[catch] "Loads XML as a Rebol compatible block of values."
XML [string! file!] "The XML string or file."
] [

Content: make block! 10
Stack: make block! 10
Namespace_Name^: [Alpha any AlphaDigit opt [#":" Alpha any Alphadigit]]

With Bryan's test XML (modified by me!):
XML: {
<?xml version="1.0"?>
<doc>
here's some text
<p>para 1</p>
<p>para 2</p>
here's some more text
<p:p xmlns:p="http://www.uris.org/p">not a para</p:p>
</doc>
}
I'm getting:
[
xml [#version "1.0"] doc [
"here's some text" p "para 1"
p "para 2" "here's some more text"
p:p [#xmlns:p "http://www.uris.org/p" "not a para"]]]
Note that the "p:p" is converted to a word! value, currently. I feel it
should be a path! value, like this:
p/p [xmlns/p "http://www.uris.org/p" "not a para"]
As too should the attribute names as well.
What do people think?
