[Htmlparser-user] Help with a link extraction program

[<Sri...@ba...>]

Hi everyone,

I am a new user of the HTMLParser API. I have found the link extraction
features to be very useful even in this short space of time.

I would like to seek help with a program that I have to write. It
involves link extraction, but the logic is slightly more convoluted.

Currently, I know how to use the LinkExtractor to supply a HTML document
as input and output the links in that document to either the command
prompt or a text file (with suitable modifications where required of
course). I have a HTML document in which there is a hierarchy of links
in the form of lists. I would like the output of the link information
given by LinkExtractor to reflect this hierarchy in some way.

For example, I have a list of items in a <ul> tag. Each of these items
may/may not contain their own sub-items with their own links, so that
the HTML looks something like:

<ul>
<li> <a href="...."> Item 1 </a>
	<ul> 
	<li> <a href="....">  Sub-Item 1 </a>  </li>
	<li> <a href="....">  Sub-Item 2 </a>  </li> 
	</ul>

<li> Item 2 </li>
</ul>

I would like to know how I can parse a document full of lists like these
and extract the links while having some indication of the hierarchy,
either the "tree path" of the link (i.e. if I extract the link
underyling Sub-Item 1 in my example, my text file should contain
something along the lines of "Item 1 > Sub-Item 1" before printing the
actual link path) or outputting a page identical to the one I am parsing
but with the full path of the link printed beside each of those list
items.

Thanks for all your help in this regard.

Warm Regards,
