具体的如何使用sax创建xml，在程序中都加了相关的注释，还是直接上代码.
package cn.com.sax;import java.io.OutputStream;import java.io.StringWriter;import javax.xml.transform.OutputKeys;import javax.xml.transform.Result;import javax.xml.transform.Transformer;import javax.xml.transform.TransformerConfigurationException;import javax.xml.transform.sax.SAXTransformerFactory;import javax.xml.transform.sax.TransformerHandler;import javax.xml.transform.stream.StreamResult;import org.xml.sax.SAXException;import org.xml.sax.helpers.AttributesImpl;import android.util.Log;class SxaCreateXml {/** * SAX方式生成XML * * @param list * @return */public String saxToXml(OutputStream output) {String xmlStr = null;try {// 用来生成XML文件// 实现此接口的对象包含构建转换结果树所需的信息Result resultXml = new StreamResult(output);// 用来得到XML字符串形式// 一个字符流，可以用其回收在字符串缓冲区中的输出来构造字符串StringWriter writerStr = new StringWriter();// 构建转换结果树所需的信息。Result resultStr = new StreamResult(writerStr);// 创建SAX转换工厂SAXTransformerFactory sff = (SAXTransformerFactory) SAXTransformerFactory.newInstance();// 转换处理器，侦听 SAX ContentHandler// 解析事件，并将它们转换为结果树 ResultTransformerHandler th = sff.newTransformerHandler();// 将源树转换为结果树Transformer transformer = th.getTransformer();// 设置字符编码transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");// 是否缩进transformer.setOutputProperty(OutputKeys.INDENT, "yes");// 设置与用于转换的此 TransformerHandler 关联的 Result// 注：这两个th.setResult不能同时启用 th.setResult(resultXml);// th.setResult(resultStr);//创建根元素<calsses>,并设置其属性为空th.startDocument();AttributesImpl attr = new AttributesImpl();th.startElement("", "calsses", "calsses", attr);//创建一级子元素<group>,并设置其属性attr.clear();attr.addAttribute("","name", "name", "", "一年级");attr.addAttribute("","num", "num", "", "10");th.startElement("", "", "group", attr);//创建二级子元素<person>,并设置其属性attr.clear();attr.addAttribute("","name", "name", "", "小明");attr.addAttribute("","age", "age", "", "7");th.startElement("", "", "person", attr);//创建三级子元素<chinese>,并设置其值attr.clear();th.startElement("", "", "chinese", attr);th.characters("语文90".toCharArray(), 0, "语文90".length());th.endElement("", "", "chinese");//创建三级子元素<english>,并设置其值th.startElement("", "", "english", attr);th.characters("英语80".toCharArray(), 0, "英语80".length());th.endElement("", "", "english");th.endElement("", "", "person");th.endElement("", "", "group");th.endElement("", "calsses", "calsses");th.endDocument();xmlStr = writerStr.getBuffer().toString();} catch (TransformerConfigurationException e) {Log.e("TEST", ""+e.toString());} catch (SAXException e) {Log.e("TEST", ""+e.toString());} catch (Exception e) {Log.e("TEST", ""+e.toString());}Log.e("TEST","生成的"+xmlStr);return xmlStr;}}调用这个方法即可实现创建xml文件的目的。
new SxaCreateXml().saxToXml(openFileOutput("sax.xml", Context.MODE_PRIVATE));
生成的sax.xml文件还是在data/data/cn.xxx.xxx/files文件夹下。
<?xml version="1.0" encoding="UTF-8"?>
<calsses><group name="一年级" num="10"><person name="小明" age="7"><chinese>语文90</chinese><english>英语80</english></person></group></calsses>
