Answer 1

you can browse the source of jQuery on git hub and import the parseXML functionality like

$(document).ready(function(){
 jQuery.extend({
     parseXML: function(data) {
        var xml, tmp;
    if ( !data || typeof data !== "string" ) {
        return null;
        }
    try {
    tmp = new DOMParser();
    xml = tmp.parseFromString( data , "text/xml" );
    } catch ( e ) {
    xml = undefined;
    }
    if ( !xml || xml.getElementsByTagName( "parsererror" ).length ) {
    jQuery.error( "Invalid XML: " + data );
    }
    return xml;  
    }
 })

var xml = "<rss version='2.0'><channel><title>RSS Title</title></channel></rss>",
xmlDoc = $.parseXML( xml ),
$xml = $( xmlDoc ),
$title = $xml.find( "title" );
console.log($title.text());
});
