kXML is a small XML pull parser, specially designed for constrained environments such as Applets, Personal Java or MIDP devices.

最小的版本只有11k,比那些龐大的xml解析起確實(shí)小好多。當(dāng)你對xml解析不需要很嚴(yán)格時(shí)可以使用它。

下面是使用kxml的一段示例代碼：

import org.xmlpull.v1.*;

import java.util.*;
import java.io.*;
import java.net.*;

 * A simple example illustrationg some differences of the XmlPull API 
 * and SAX. For the corresponding SAX based implementation, please refer to

    static List listChannels()
        throws IOException, XmlPullParserException {
        return listChannels("http://static.userland.com/weblogMonitor/logs.xml");
    }

    static List listChannels(String uri)
        throws IOException, XmlPullParserException {

        Vector result = new Vector();

        InputStream is = new URL(uri).openStream();
        XmlPullParser parser =
            XmlPullParserFactory.newInstance().newPullParser();

        parser.setInput(is, null);

        parser.nextTag();
        parser.require(XmlPullParser.START_TAG, "", "weblogs");

        while (parser.nextTag() == XmlPullParser.START_TAG) {
            String url = readSingle(parser);
            if (url != null)
                result.addElement(url);
        }
