Sample RSS Reader to perform multiple text processing on xml text of a rss feed.
Reads from a variety of inputs sources and Writes to a variety of outputs desination are supported.
PyRssReader deliberately has OOPS as design pattern to demonstrate OOPS in python.

Usage

Sample command

python PyRssReader --input http://globalissues.org/news/ --convert="cut,replace(/base/acid/)" -o tmp.txt
python PyRssReader --input http://globalissues.org/news/ --convert=cut
python PyRssReader --input articles.txt --convert="replace(/social/Social/)" -o out.txt

4. REPLACE function will be applied on the text inside the tags <title>, <subtitle>, <author>, <content>, etc inside of xml file

Implementation

• Objects have been heavily used for separation of concerns
• Code reusability and extensibility have been given extra importance.
