This version of SickBeard uses both TVDB and TVRage to search and gather it's series data from allowing you to now have access to and download shows that you couldn't before because of being locked into only what TheTVDB had to offer. Also this edition is based off the code we used in our XEM editon so it does come with scene numbering support as well as all the other features our XEM edition has to offer. Please before using this with your existing database (sickbeard.db) please make a backup copy of it and delete any other database files such as cache.db and failed.db if present, we HIGHLY recommend starting out with no database files at all to make this a fresh start but the choice is at your own risk! Enjoy!

|
|
Beautiful Soup uses a pluggable XML or HTML parser to parse a
|
|
(possibly invalid) document into a tree representation. Beautiful Soup
|
|
provides provides methods and Pythonic idioms that make it easy to
|
|
navigate, search, and modify the parse tree.
|
|
|
|
Beautiful Soup works with Python 2.6 and up. It works better if lxml
|
|
and/or html5lib is installed.
|
|
|
|
For more than you ever wanted to know about Beautiful Soup, see the
|
|
documentation:

These methods will be called by the parser:

reset()

The tree builder may call these methods from its feed() implementation:
|
|
handle_starttag(name, attrs) # See note about return value

handle_endtag(name)

handle_data(data) # Appends to the current data node
|

endData(containerClass=NavigableString) # Ends the current data node

No matter how complicated the underlying parser is, you should be
|

able to build a tree using 'start tag' events, 'end tag' events,
|
|
'data' events, and "done with data" events.
|
|
|
|
If you encounter an empty-element tag (aka a self-closing tag,

like HTML's <br> tag), call handle_starttag and then

handle_endtag.
