how to parse this xml in jquery to get an attribute?

Question

I need to parse the following example XML in jquery, to get the attribute "V"

XML file:

<RES>
<R N="1">
    <MT N="myMeta1" V="myMeta1Value"/>
    <MT N="myMeta2" V="myMeta2Value"/>
    <MT N="myMeta2" V="myMeta2Value"/>
</R>
</RES>

And my javascript is the following:

function(data){
$(data).find('R').each(function(){
    var $result = $(this);
    $result.find('MT').each(function(_mt) {
            console.log($(_mt).attr("V") );
    });
});

}

I get undefineds, what am I doing wrong?

The first argument to .each callback is the index, the second one is the value. You can also use this:

$result.find('MT').each(function() {
        console.log($(this).attr("V") );
});

Or:

$result.find('MT').each(function( index, _mt ) {
        console.log($(_mt).attr("V") );
});

You are using index as an element in each. As first parameter is index pass two parameter in each and use the second to get the element.

function(data){
  $(data).find('R').each(function(){
      var $result = $(this);
      $result.find('MT').each(function(_mt, obj) {
            console.log($(obj).attr("V") );
      });
   });
}
