javascript - how to convert xml document object to string?

I have xml that I have in a string. I want to change some attributes in it.
So what I have done is

var xml //contains xml  
parser = new DOMParser()
xmlDoc = parser.parseFromString(xml, "text/xml")
xmlDoc.setAttribute("name", "random")

Now the xmlDoc has the required changes. But how do I get the string representation of the xml again?

You will need to serialize your xmlDoc back to XML once you have made the changes:

var s = new XMLSerializer();
var newXmlStr = s.serializeToString(xmlDoc);

Now you can do what you need to do with the string of updated XML, overwrite your xml variable, or send it to the server, or whatever...
