XML解析之四：Stax

这个是从JDK1.6支持的Stax解析，类似于Linux的pull，和sax的push有一些区别。但都是流模式。适用于J2ME。

import java.io.FileNotFoundException;
import java.io.FileReader;

import javax.xml.stream.XMLInputFactory;
import javax.xml.stream.XMLStreamConstants;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamReader;

public class StaxTest {
    // 获得解析器
    public static XMLStreamReader getStreamReader() {
        // String xmlFile = StaxTest.class.getResource("/").getFile()+ "users.xml";
        String xmlFile = "c:\\company.xml";
        XMLInputFactory factory = XMLInputFactory.newInstance();
        //XMLInputFactory factory = XMLInputFactory.newFactory();  // the all equal
        try {
            XMLStreamReader reader = factory.createXMLStreamReader(new FileReader(xmlFile));
            return reader;
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (XMLStreamException e) {
            e.printStackTrace();
        }
        return null;
    }

    // 列出所有用户名称
    public static void listNames() {
        XMLStreamReader reader = StaxTest.getStreamReader();
        // 遍历XML文档
        try {
            while (reader.hasNext()) {
                int event = reader.next();
                // 如果是元素的开始
                if (event == XMLStreamConstants.START_ELEMENT) {
                    // 列出所有用户名称
                    if ("user".equalsIgnoreCase(reader.getLocalName())) {
                        System.out.println("Name:" + reader.getAttributeValue(null, "name"));
                    }
                }
            }
            reader.close();
        } catch (XMLStreamException e) {
            e.printStackTrace();
        }
    }

    /**
     * @param args
     */
    public static void main(String[] args) {
        System.out.println("**********Start****************");
        StaxTest.listNames();
        System.out.println("**********End****************");
    }

}

解析的文件：company.xml
