问题
I am parsing a xml using SAX Parser. Everythings working fine when the data I need to get is the body of a xml tag. The only problem I am getting is when the data I need is the attribute value of that XML tag. How do i get this attribute value?
<xml att="value"> Body </xml>
Suppose this is a tag, I am able to get Body but not value
code I am using is:
URL url = new URL("http://example.com/example.xml");
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
ExampleHandler myExampleHandler = new ExampleHandler();
xr.setContentHandler(myExampleHandler);
xr.parse(new InputSource(url.openStream()));
public class ExampleHandler extends DefaultHandler {
String buff = new String("");
boolean buffering = false;
@Override
public void startDocument() throws SAXException {
// Some sort of setting up work
}
@Override
public void endDocument() throws SAXException {
// Some sort of finishing up work
}
@Override
public void startElement(String namespaceURI, String localName, String qName,
Attributes atts) throws SAXException {
if (localName.equals("qwerasdf")) {
buff = new String("");
buffering = true;
}
}
@Override
public void characters(char ch[], int start, int length) {
if(buffering) {
buff=new String(ch, start, length)
}
}
@Override
public void endElement(String namespaceURI, String localName, String qName)
throws SAXException {
if (localName.equals("blah")) {
buffering = false;
String content = buff.toString();
// Do something with the full text content that we've just parsed
}
}
回答1:
@Override
public void startElement(String namespaceURI, String localName, String qName,
Attributes atts) throws SAXException {
if (localName.equals("xml")) {
System.out.println("The value of attribute 'att' is: " + atts.getValue("att"));
}
}
