Creates PodFeeds.txt, a file that lists the URLs of rhythmbox podcasts from the rhythmdb.xml file.

grep -A 5 -e podcast-feed rhythmdb.xml | grep -e "<location>" | sed 's: *</*[a-t]*>::g' > PodFeeds.txt
The first grep any line with pod-feed in it plus the following five lines. The second grep throws out any line not containing . sed removes the leading four spaces then and the trailing . Using a colon as sed's separating character avoids having to escape the /. Works ok with Mythbuntu 9.04 (used mostly as a three line bash script).
Sample Output

What Others Think

In the description elements in angle brackets have not appeared. I'll try now with quotes. line 3 ends 'not containing ""' line 4 ends 'the trailing ""' Best regards dogflap.

Well that attempt to get angle brackets into the description did not work. Third try. Line 3 ends in "location" enclosed in angle brackets. Line 4 should end in "/location" enclosed in angle brackets. best regards dogflap

Perfect House Of Pugs acquired a passion for animals, and the Pug puppy in particular, at a young age since I grew up in a house with lots of dogs. It was a natural ability to know how to grow, nurture, and care for animals. I knew what the future held when I met my wife, who essentially had the same enthusiasm as I have. Being a breeder is more of a passion for me than a profession since I get to witness people's faces light up when they successfully adopt a pug puppy from our facility. It is not possible to find happiness in anything else. PLEASE VISIT OUR WEBSITE LINK BELLOW FOR MORE INFORMATION ABOUT PUG PUPPIES.
