I would use JDOM ( http://www.jdom.org ) in the following manner:
import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.util.Iterator;
import java.util.List;
import org.jdom.Attribute;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.JDOMException;
import org.jdom.filter.ElementFilter;
import org.jdom.input.SAXBuilder;
/*

/**

*/
public class ParserSpike {
private File inputFile;
/**
* @param outputFile
* @param inputFile
*
*/
public ParserSpike(File inputFile) {
super();
this.inputFile = inputFile;
if (!inputFile.exists()) {
System.out.println("The input file" +
inputFile.getPath()
+ "does not exist");
System.exit(1);
}
}
public static void main(String[] args) {
File inputFile = new File(args[0]);
new ParserSpike(inputFile).run();
}
/**
*
*/
private void run() {
Document document = null;
URL fileURL;
SAXBuilder builder = new SAXBuilder();
try {
fileURL = inputFile.toURL();
document = builder.build(fileURL);
Element rootElement = document.getRootElement();
Iterator elementList = rootElement.getDescendants(new
ElementFilter("element"));
while (elementList.hasNext()) {
Element nextElement = (Element)
elementList.next();
List attributeList =
nextElement.getAttributes();
Iterator attributeIterator =
attributeList.iterator();
while (attributeIterator.hasNext()) {
Attribute attribute = (Attribute)
attributeIterator.next();
System.out.print(attribute.getName() +
" = " +attribute.getValue() + " ");
}
System.out.println();
}
} catch (IOException e) {
e.printStackTrace();
} catch (JDOMException e) {
e.printStackTrace();
}
}
}
The Output is the following:
name = data type = int
name = programName type = string
name = managerHost type = string
name = value type = string
name = dataType type = string
name = sensorName type = string
