IE 6 & 7 selector bug when using complex selector

[emartin24]

I have a form that uses array notation in the input element name attribute. I am able to select a particular element with the following:

  jQuery('input[type=hidden][name=ruleDto\\.operators\\[0\\]\\.operands\\[1\\]\\.descr]');

If I add an ID selector to the beginning, it no longer works in IE6 or IE7:

  jQuery('#one input[type=hidden][name=ruleDto\\.operators\\[0\\]\\.operands\\[1\\]\\.value]');

In order to get the correct results, I am able to use the filter function:

  els = $$('#one input:hidden').filter(function (idx) {
    return this.name === 'ruleDto.operators[0].operands[1].value';
  });

I've placed sample code online: ​http://www.ericmmartin.com/code/jquery/selector/

The provided test cases work as follows in IE based browsers:

IE 9: passes IE 8: passes IE 7: fails IE 6: fails

As mentioned, a work-around is available for this type of behaviour and given that there are currently more critical bugs to be fixed in the core, I am flagging this for a low-priority patch.

Caused by #6448.

(In #6093) ​test case with explanation:

First and third test cases should fail everywhere. qSA throws a SYNTAX_ERR because they are not valid, which causes Sizzle to pick them up and try again, and it matches because it is parsing the strings incorrectly.

Second and forth test cases should pass everywhere. IE6-7 do not have qSA support they go to Sizzle, and since Sizzle is parsing the strings wrong they fail in IE6-7.

​test case

Still not fixed. Quoted/unquoted escaped attribute selectors fail in browser with no qSA if an element-rooted query is made.
