[jQuery] selector ":contains" different behaviour in firefox and msie 7


hi,
i have a strange behaviour when parsing the xml below:
$.get('/test/Internetschuhe.XML', function(data) {
$(data).find('item').each(function() {
var $entry = $(this);
var $sizenotnull = $entry.find("stock:contains('0')");
alert($sizenotnull.length);
in firefox it works... the alert is 1 and thats right... i have one
size with the stock 0
in msie7 the alert is 0... why... is it a bug?
best regards
m cologne
