关于在servlet中读写xml

[ye_zhy]

我想在servlet中读a.xml，然后把里面的数据写到b.xml中。应该怎么写。各位大虾救命啊～～（a.xml中比如说有abcde5个节点，要把abc3个节点存到b.xml中去）。

用xsl来转换，下面是一个简单的转换类。

import javax.xml.transform.TransformerFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;
import java.io.FileReader;
import java.io.FileWriter;

public class TrAXUtil {

private static TransformerFactory tf = null;

public static void main(String[] args) throws Exception {
if (args.length != 3) {
System.out.println("Usage: java TrAXUtil XML XSL OUT");
}
tf = TransformerFactory.newInstance();
StreamSource xml = new StreamSource(new FileReader(args[0]));
StreamSource xsl = new StreamSource(new FileReader(args[1]));
StreamResult htm = new StreamResult(new FileWriter(args[2]));
Transformer t = tf.newTransformer(xsl);
t.transform(xml,htm);
}

}
