194 GOOGLE APPS HACKS
HaCK 78:
Switching your feed reader doesn’t need to cause a lot of
headaches.
If you were using another feed reader before Google Reader, you might want to take your old
subscriptions with you. Wouldn’t it be nice to move all of them at once instead of having to
resubscribe to feed URL after feed URL? Luckily, there’s a perfect format for just that, called OPML.
OPML, the Outline Processor Markup Language, collects several RSS feed addresses within a
single le.
For instance, if your old feed reader is Bloglines (http://bloglines.com), log into it and in the lefthand
navigation, click the “Export Subscriptions” link, pictured in Figure 8-7. An OPML download will be
offered to you; save it to your computer. If you are curious, you can open the download le with a
plain text editor, and you will see something along the lines of the following—a structured list of feed
URLs in XML format:
<?xml version="1.0" encoding="utf-8"?>
<opml version="1.1">
<head>
<title>Bloglines Subscriptions</title>
...
