Deserializing and Reserializing XML in JavaScript

The JavaScript code below, when run, displays an XML-formatted text string, deserializes it into an an XMLDocument object, re-serializes that object into another text string, and then displays that text string. To see it in action, copy it into an .html file and open that file in a web browser that runs JavaScript.


<script type="text/javascript">

function main()
	var xmlStringToParse = 
		"<artist name='The Jimi Hendrix Experience'>"
		+ " <albums>"
		+ "  <album name='Are You Experienced?' year='1967'></album>"
		+ "  <album name='Axis: Bold as Love' year='1967'></album>"
		+ "  <album name='Electric Ladyland' year='1968'></album>"
		+ " </albums>"
		+ "</artist>";

	document.write("XML before parsing:<br/><br/>");

	var parser = new DOMParser();
	var xmlDocument = parser.parseFromString
		xmlStringToParse, "text/xml"

	var serializer = new XMLSerializer();
	var xmlStringReserialized = serializer.serializeToString(xmlDocument);
	document.write("XML after reserialization:<br/><br/>");

function escapeStringForHTML(valueToEscape)
	return valueToEscape.replace
		/</g, "&lt;"
		/>/g, "&gt;"
