Extract a specific table of data out of scraped content. The class
comes with 2 static methods you can use for this purpose.
table_into_array() will rip a single table into an array.
table_into_xml() will internally call table_into_array() then create an
XML document from the array. I thought this would be cool, but in practice,
I've never used this method since the array is so easy to work with.
This example builds on the previous example to extract the MSFT stats out
of the body content. Read the comments in the class file to learn how to use
this static method.

authentication. Pass your username and password in like this:

If your need to access content on a port other than 80, just put the port in
