Hi,

You can parse this XML string using either the DOM/SAX APIs. The code looks like this:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = factory.newDocumentBuilder();
Document doc = documentBuilder.parse(new InputSource(new StringReader(XMLString)));
NodeList nlist=doc.getElementsByTagName("businessForm");
String attrVal = nlist.item(0).getAttributes().getNamedItem("guid").getNodeValue();

The simplest way:

int i = xml.indexOf("guid=\"");

if (i >= 0) {

int j = xml.indexOf("\"", i + "guid=\"".length());

if (j >= 0) {

String result = xml.substring(i, j);

}

}

Hi,

You can use DOM parser or Pattern class.

In case of Pattern Class, split function should help.

For DOM Parser,something like this

var parser = new DOMParser();

var doc = parser.parseFromString("<items><item name='Apple'/><items>", "text/xml");

Once parsed, you can read elements ,attributes etc.,
