Since you have well formed HTML, you can create a document and select nodes from it:

var doc = (new DOMParser()).parseFromString(htmlstring,"text/html");
console.log(doc.head.outerHTML);
console.log(doc.body.outerHTML);

Here is a demonstration: http://jsfiddle.net/X3Uq2/

In Chrome, you can't use a "text/html" content type, so you have to make an XML document and use getElementsByTagName:

var s = new XMLSerializer();
var doc = (new DOMParser()).parseFromString(data,"text/xml");
console.log(s.serializeToString(doc.getElementsByTagName("head")[0]));
console.log(s.serializeToString(doc.getElementsByTagName("body")[0]));
