使用jQuery选择自定义类似fbml的标签

FBML使用的标签如< fb：like>< / fb：like> < fb：board>< / fb：board>等.

他们如何选择这些？我试过$(‘fb’)和$(‘fb：like’),都返回一个空对象……有谁知道如何做到这一点？

比如这个,

<fb:like href="http://google.com" layout="box_count" show_faces="false" width="450"></fb:like>

/*

If you wish to use any of the meta-characters 
( such as !"#$%&'()*+,./:;?@[\]^`{|}~ ) as a literal part of a name, 
you must escape the character with two backslashes: \\. For example, 
if you have an an element with id="foo.bar", you can use the selector 
$("#foo\\.bar").
