With the DOMParser API , you can turn XML into DOM element, and therefore you can use getElementById or getElementsByTagName ... methods :

var parser = new DOMParser();
var doc = parser.parseFromString(yourXML, "text/xml");

EDIT

var parser = new DOMParser();
var doc = parser.parseFromString('<resultset> <set> <type>type1</type> <name>Patil</name> <date>2015-03-21</date> <tag>ThisIsALongText-|tag_machine</tag> <c_date>2015-01-12</c_date> </set> <set> <type>type1</type> <name>Patil</name> <date>2016-06-11</date> <tag>ThisIsALongText-|tag_human</tag> <c_date>2013-07-17</c_date> </set> <set> <type>type1</type> <name>Patil</name> <date>2016-05-21 </date> <tag>ThisIsALongText-|tag_software</tag> <c_date>2014-11-12</c_date> </set> <set> <type>type1</type> <name>Patil</name> <date>2015-12-10</date> <tag>ThisIsALongText-|tag_human</tag> <c_date>2015-04-12</c_date> </set> <set> <type>type1</type> <name>Patil</name> <date>2015-03-21</date> <tag>ThisIsALongText-|tag_machine</tag> <c_date>2016-02-23</c_date> </set>', "text/xml");
var set = doc.getElementsByTagName('set');
var dates = doc.getElementsByTagName('date');
var date1Month = dates[0].innerHTML.split('-')[1];
var date1Year = dates[0].innerHTML.split('-')[0];

var arrDates = [].map.call(dates, function(element) { return element; });

var allDates = arrDates.map(function(date) { return date.innerHTML });

You can use jQuery to parse XML, there is a $.parseXML function.

Use it like this :

var xml = $.parseXML(myXML);
var tags = $(xml).find('tag');

The variable tags will be an array of all your tags.
