Parsing xml string in Java

JDOM

[code language=”java”]
String xml = "<message>HELLO!</message>";
org.jdom.input.SAXBuilder saxBuilder = new SAXBuilder();
try {
org.jdom.Document doc = saxBuilder.build(new StringReader(xml));
String message = doc.getRootElement().getText();
System.out.println(message);
} catch (JDOMException e) {
// handle JDOMException
} catch (IOException e) {
// handle IOException
}
[/code]

Xerces

[code language=”java”]
String xml = "<message>HELLO!</message>";
DOMParser parser = new DOMParser();

parser.parse(new InputSource(new java.io.StringReader(xml)));
Document doc = parser.getDocument();
String message = doc.getDocumentElement().getTextContent();
System.out.println(message);
} catch (SAXException e) {
// handle SAXException
} catch (IOException e) {
// handle IOException
}
