轻量级的xml parser: KXML

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,比那些庞大的xml解析起确实小好多。当你对xml解析不需要很严格时可以使用它。

下面是使用kxml的一段示例代码：

import org.xmlpull.v1.*;

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

/**

* and SAX. For the corresponding SAX based implementation, please refer to

public class Weblogs {

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);
}
parser.require(XmlPullParser.END_TAG, "", "weblogs");

parser.next();
parser.require(XmlPullParser.END_DOCUMENT, null, null);

is.close ();
parser.setInput (null);

return result;
}

public static String readSingle(XmlPullParser parser)
throws IOException, XmlPullParserException {

String url = null;
parser.require(XmlPullParser.START_TAG, "", "log");

while (parser.nextTag() == XmlPullParser.START_TAG) {
String name = parser.getName();
String content = parser.nextText();
if (name.equals("url"))
url = content;
parser.require(XmlPullParser.END_TAG, "", name);
}
parser.require(XmlPullParser.END_TAG, "", "log");
return url;
}

public static void main(String[] args)
throws IOException, XmlPullParserException {

List urls =
args.length > 0
? listChannels(args[0])
: listChannels();

for (Iterator i = urls.iterator(); i.hasNext();)
System.out.println(i.next());
}
}
