Good!

Server side using jquery is really useful for extracting useful
information on remote sites without using many regex...

Simply: Because one doesn't exist. I've since written one and hope to
be integrating it soon.

from John's site, it said:

This is one part that works pretty well right now - with the huge
caveat that it only works on well-formed XML documents (oops!). I'll
be integrating an HTML parser into the code base so that we can make
this functionality a little more resilient. In the meantime, here's an
example of the sort of scraping that you can do currently:

I am wondering why it was difficult to parse HTML at the beginning.

You don't have to use XML for sure, you can use JSON and fetch
Javascript data structures from the server-side. I think it's often
much easer for a server-side developer.. or you can just "load" plain
html text into your DOM tree(usually into a single field).
