Read XMLString - urgent

[GSL_NARAYANA]

Hi,

I have a string which holds a valid XML

some thing like this

strXML = "<GSP ver='3.2'><tm>7.622</tm><RES SN='1'><M>126000</M></RES></GSP>";

Can any one tell me how to get the value of "126000" from the above XMLstring in EP.

Note: I want to use DOM parser to get the value.

Thanks in advance

Hi, if you are shure there is just one Element named "M" you can also read the value this way:

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

factory.setNamespaceAware(true);DocumentBuilder

docbuilder = null;

try

{

docbuilder = factory.newDocumentBuilder();

}

catch (ParserConfigurationException pce){pce.printStackTrace();}

try

{

Document XML_in = docbuilder.parse(XMLStr);

if (XML_in.getElementsByTagName("M").item(0) != null)

{

Element elem_m = (Element) id.getElementsByTagName

("M").item(0);

String m = elem_m.getFirstChild().getNodeValue();

}

catch (SAXException sxe){sxe.printStackTrace();}

Hello Lakshminarayana,

Try this (untested) example. If it works and you like it, improve it.

Regards.

....

String number;

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(true);

DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(strXML);

NodeList items = document.getFirstChild().getChildNodes();

for (int x = 0; x < items.getLength(); x++) {

		Node nodo = items.item(x);

		if (nodo.getNodeName() == "RES") number = getNumber(nodo);
		

}

....

private String getNumber(Node nodo){

	String number;
	
	NodeList items = nodo.getChildNodes();

	for (int x = 0; x < items.getLength(); x++) {

		Node child = items.item(x);
			
		if (child.getNodeName() == "M") number = child.getFirstChild().getNodeValue();
		
		//This will work only if you have just 1 M node in a RES node.
		
	}
	
	return number;

}
