Parsing XFN data with Jquery

I'm trying to filter the XFN relationships meta data found in web pages. It is something like this:

<a href="site" rel="friend colleague" >Name</a>

in REL you can have various values, like "friend", "collegue" but even "me" and "met" because you can have multiple values, I did this: 

xfn_me = $("a[rel*=me]").length;

But this doesn't work, because both "me" and "met" are matched! Is there a way to filter the values exactly, even when there are multiple values?

Thank you.

Please note that I have no control on the page, in fact I'm working on a Chrome extension, and this code should runs on any web page.

Solution

  • You could use the [attribute~=value] selector. It selects based on space-separated values exactly like how xfn and CSS classes work, i.e. [class~=className] is exactly the same as .className.

    xfn_me = $("a[rel~=me]").length;

    I couldn't find it in the jQuery documentation, but it works in 1.3 at least.
