JavaScript SDK: FB.XFBML.parse()

This function parses and renders XFBML markup in a document on the fly. This could be used if you send XFBML from your server via ajax and want to render it client side. XFBML enables you to incorporate FBML into your websites and IFrame applications.

You can use this function to re-render social plugins using either the XFBML syntax (e.g. <fb:like>) or the HTML5 syntax (e.g. <div class="fb-like">)

To re-parse all of the XFBML on a page, you can call:

FB.XFBML.parse();

Alternately, to only evaluate a portion of a document, you can pass in a single element.

FB.XFBML.parse(document.getElementById('foo'));
