eva rgs src XML throw conf value tle tag
XML文檔格式內容如下
<?xml version="1.0" encoding="UTF-8"?>
<root>
<field type="1" store="yes">title1</field>
<field type="2" store="no">title2</field>
<field type="3" store="yes">title3</field>
</root>
JAVA代碼如下
import java.io.File;
importjava.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;
public class MyXml {
public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
//讀取XML文件
File f = new File("E:\\workspace\\cn.harmel.lucene\\src\\1.xml");
//獲取DocumentBuilderFactory
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); //通過DocumentBuilder工廠產生一個DocumentBuilder
DocumentBuilder builder = factory.newDocumentBuilder();
//利用DocumentBuilder產生Document
Document doc = builder.parse(f);
//獲取指定的標簽的集合
NodeList nl = doc.getElementsByTagName("field");
for (int i = 0; i < nl.getLength(); i++) {
String fieldName=nl.item(i).getFirstChild().getNodeValue();//獲取標簽值
String fieldType=nl.item(i).getAttributes().getNamedItem("type").getNodeValue();//獲取標簽屬性值
String fieldStore=nl.item(i).getAttributes().getNamedItem("store").getNodeValue();//獲取標簽屬性值
System.out.println(fieldName+"------"+fieldType+"------"+fieldStore);
}
}
}
