Sizzle.filter and xml

On Sizzle.filter,line: for ( var i = 0; (item = curLoop[i]) !== undefined; i++ ) { … } you use strict “!==”,so you’ll get “true” if curLoop[i] is “null”.But for xml node lists access to not existent element in list result “null” not “undefined”,like in html dom. Maybe you want to gain another millisecond,but in this case just do “!=”,it’s enough and correct IMHO.

Beta 2 of 1.3 still have that bug.

Thanks.

That only true for IE: function test() var doc= window.ActiveXObject

? new ActiveXObject("msxml2.domdocument") : document.implementation.createDocument("", "", null) return doc.childNodes[0]!==undefined;

} In IE it will be "true" but in Chrome(for example) it will be "false".

Landed a fix for this:  http://github.com/jeresig/sizzle/commit/76fbebec12e998f2ce42c83084c3c9c406942986

Not sure why I was being so strict to begin with (was doing != null everywhere else).
