I need some advice about reading rel="me" tags in arbitrary web pages
using PHP. I'm intending to use this to help build a lifestream style
function. The basic intent is to cut down the amount of data entry the
user has to do. When they give me a MyBlogLog, Friendfeed, Plaxo Pulse
page that has lists of links to their profile pages I should be able to
avoid having to ask them for all of them again. So:-
- User gives me a URL for one of their profile pages
- Use Curl to collect the source
- Parse the source looking for links with a rel="me"
- Extract an array of Link URL - Link Text
- Do something useful with the array. (???? followed by Profit!)
I've been searching this morning for a PHP library to do the parsing and
link extraction or PHP examples or example regex to use in
PREG_MATCH_ALL or something/anything, without success. Since the source
data is probably badly written and broken html, I don't think I can use
XML methods as all the XML unserialising code I've used barfs on badly
formed XML. One possibility I suppose is to run it though HTML-Tidy
first but I run the (admittedly small) chance of html-tidy wiping out
some of the links.
So what do people use to consume XFN with PHP?
