You should always try to get feed URLs programmatically, either by
parsing out <link> tags in a blog's <head> section, or by looking at
the results of the per-user metafeed.
In the users metafeed, there are five link tags: one 'alternate', two
that point to a schema.google.com, a 'self' link and an 'edit' link.
Is it safe to just parse out the link tag with rel="http://
schemas.google.com/g/2005#post" for finding the posting URL and
likewise do the same for the feed URL? Is this the correct way to get
the two URL's instead of having to pull down the users blog and
parsing the 'head' tag? (I'm on a mobile device so I'd rather not have
to pull down any more content then I need to.)
Also, in the users metafeed, what are the 'self' and 'edit' URL's used
for? If I just drop them into a web browser, I get back a simple HTML
page that says "Invalid Blog ID". I don't see where I would use them
programatically for posting or reading.
Thanks again for the help,
