quote problem on IE6

Hi,

here's my code :

var linkpath = "test'it";
var thislink = $('a[rel=" ' +linkpath+ ' "]');

It woks fine on Firefox with the character quote ' inside linkpath
value, but IE6 return a "no value" javascript error.
I just want IE6 to not understand linkpath inside quote as quote which
define the end of my attribute value.
I searched around, tried many ways to escape quotes, replace it with
& # 39 ; , etc... but I don't get it.

By the way, is there anyway to set thislink without using simple
quote, like :

var thislink = $("a[rel=" +linkpath+ "]"); // doesn't work, but you
get the idea

Can anyone help me ? Thanks a lot.
