Java XML Helper Utilities is a set of utilites written in Java that can help you manipulate, edit or extract XML attributes..

Here a a couple of examples against the XML Payload below:

Example 1 - Modify the multiple items using a TreeMap.

	long newTime = System.currentTime();
	String xmlPayLoad = readFileAsString(payLoadPath + "/payLoad.xml");
	TreeMap<String, String> header = new TreeMap<String, String>();
	XPathHelperCommon xph = new XPathHelperCommon();
	header = xph.findMultipleXMLItems(xmlPayLoad, "//header/*");
	header.put("type", "newProcess");
	newTime += Long.parseLong(header.get("taskElapsedTime"));
	header.put("taskElapsedTime", Long.toString(newTime));
	xmlPayLoad = xph.modifyMultipleXMLItems(xmlPayLoad, "//header/*", header);

.

Example 2 - Modify a single attribute

	long notAfter = System.currentime();
	itemPath = "//payload/joinAttribute/notAfter/text()";
	xmlpayLoad = XPathHelper.modifyXMLItem(xmlpayLoad, itemPath, Long.toString(notAfter));
