Selecting information from several web pages...

Hi All!

Is this possible?

I know of several hundreds of urls linking to similar looking hp-ux man pages, like these. In these urls only the last words separated by / are changing in numbering, so we can generate these...

http://docs.hp.com/hpux/onlinedocs/B...3/331-con.html

I know that all these pages follow a certain pattern in their layout. I want to make a small consolidated report of all hp-ux commands listed in these pages with only their, say descriptions, examples etc...

If I have a command which works in a loop on such urls and in each turn return me the page contents, I can filter out sections which I want...

Is this possible? Any hint is highly appreciated...

Also is there a UNIX utility which converts html to simple readable text?

Cheers!
Vishnu.

NAME
urlwatch - Watch web pages and arbitrary URLs for changes SYNOPSIS
urlwatch [options] DESCRIPTION
urlwatch watches a list of URLs for changes and prints out unified diffs of the changes. You can filter always-changing parts of websites by providing a "hooks.py" script. OPTIONS
--version show program's version number and exit -h, --help show the help message and exit -v, --verbose Show debug/log output --urls=FILE Read URLs from the specified file --hooks=FILE Use specified file as hooks.py module -e, --display-errors Include HTTP errors (404, etc..) in the output ADVANCED FEATURES
urlwatch includes some advanced features that you have to activate by creating a hooks.py file that specifies for which URLs to use a spe- cific feature. You can also use the hooks.py file to filter trivially-varying elements of a web page. ICALENDAR FILE PARSING This module allows you to parse .ics files that are in iCalendar format and provide a very simplified text-based format for the diffs. Use it like this in your hooks.py file: from urlwatch import ical2txt def filter(url, data): if url.endswith('.ics'): return ical2txt.ical2text(data).encode('utf-8') + data # ...you can add more hooks here... HTML TO TEXT CONVERSION There are three methods of converting HTML to text in the current version of urlwatch: "lynx" (default), "html2text" and "re". The former two use command-line utilities of the same name to convert HTML to text, and the last one uses a simple regex-based tag stripping method (needs no extra tools). Here is an example of using it in your hooks.py file: from urlwatch import html2txt def filter(url, data): if url.endswith('.html') or url.endswith('.htm'): return html2txt.html2text(data, method='lynx') # ...you can add more hooks here... FILES
~/.urlwatch/urls.txt A list of HTTP/FTP URLs to watch (one URL per line) ~/.urlwatch/lib/hooks.py A Python module that can be used to filter contents ~/.urlwatch/cache/ The state of web pages is saved in this folder AUTHOR
