NanoXML组件解析xml实例：
noaoxml组件对xml格式的字符串解析，效率很高
代码如下：
package com.yanek.demo.xml.test;
import java.util.Vector;
import javolution.context.ObjectFactory;
import net.n3.nanoxml.IXMLElement;
import net.n3.nanoxml.IXMLParser;
import net.n3.nanoxml.IXMLReader;
import net.n3.nanoxml.StdXMLReader;
import net.n3.nanoxml.XMLException;
import net.n3.nanoxml.XMLParserFactory;
import org.apache.log4j.Logger;
public class NanoXMLTest {
private static Logger logger = Logger
.getLogger(NanoXMLTest.class.getName());
/**
* @param args
*/
public static void main(String[] args) {
String config = "<actions id=/"123/" name=/"test/"><action path=/"/test/" class=/"com.mystruts.demo.LoginAction/"><forward name=/"success/" url=/"hello.jsp/"/><forward name=/"fail/" url=/"fail.jsp/"/></action><action path=/"/user/" class=/"com.mystruts.demo.UserAction/"><forward name=/"success/" url=/"list.jsp/"/><forward name=/"fail/" url=/"fail.jsp/"/></action></actions>";
IXMLParser xmlParser = null;
IXMLReader xmlReader = null;
long a = System.currentTimeMillis();
xmlParser = NanoXMLTest.XMLPARSER_FACTORY.object();
xmlReader = StdXMLReader.stringReader(config);
xmlParser.setReader(xmlReader);
try {
IXMLElement root = (IXMLElement)xmlParser.parse();
System.out.println(root.getAttribute("id", ""));
System.out.println(root.getAttribute("name", ""));
Vector actions= root.getChildrenNamed("action");
for (int i=0;i<actions.size();i++)
{
IXMLElement action = (IXMLElement)actions.elementAt(i);
System.out.println(action.getAttribute("path", ""));
System.out.println(action.getAttribute("class", ""));
Vector forwards=action.getChildrenNamed("forward");
for (int j=0;j<actions.size();j++)
{
IXMLElement forward = (IXMLElement)forwards.elementAt(j);
System.out.println(forward.getAttribute("name", ""));
System.out.println(forward.getAttribute("url", ""));
}
}
} catch (XMLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static ObjectFactory<IXMLParser> XMLPARSER_FACTORY = new ObjectFactory<IXMLParser>() {
protected IXMLParser create() {
try {
return XMLParserFactory.createDefaultXMLParser();
} catch (ClassNotFoundException e) {
logger.error(e);
} catch (InstantiationException e) {
logger.error(e);
} catch (IllegalAccessException e) {
logger.error(e);
}
return null;
}
};
}
输出：
