Description of the bug
The jQuery API says that:
When multiple DOM elements are in the original set, the resulting set will be in reverse order of the original elements as well, with duplicates removed
If the selector is supplied, the elements will be filtered by testing whether they match it.
Initial testing shows the current querypath functionality doesn't correctly filter the results by the selector:
<?xml version="1.0"?>
<ns1:AmplifyResponse xmlns:ns1="http://amplify.hapax.com">

-->
<AmplifyReturn>
<Demographics>
<Age>
<Name>Adult</Name>
<Value>-0.007067</Value>
</Age>
<Gender>
<Name>Neutral</Name>
<Value>0.000000</Value>
</Gender>
<Education>
<Name>Secondary</Name>
<Value>2.000000</Value>
</Education>
</Demographics>
</AmplifyReturn>
</ns1:AmplifyResponse>Using the above XML, if you run qp($xml, 'Demographics > Age > Name')->parents('Demographics') you would expect to only get the <Demographics> node returned. Querypath currently returns <AmplifyReturn> and <ns1:AmplifyResponse> as well.
If you feed the same data into jQuery you only get the <Demographics> node returned.
