之前一篇 借助DOM4J完成了解析工作,下面采用原始的DOM方式完成相同的工作,如果运行不了,你可能还需要导入xalan.jar包。
import java.io.File; import java.io.PrintWriter; import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.transform.OutputKeys; import javax.xml.transform.Source; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerFactory; import javax.xml.transform.dom.DOMSource; import javax.xml.transform.stream.StreamResult; import org.apache.xpath.XPathAPI; import org.w3c.dom.Document; import org.w3c.dom.Element; import org.w3c.dom.Node; import org.w3c.dom.NodeList; public class DomTest { public static void main(String[] args) throws Exception { DocumentBuilderFactory domFactory = DocumentBuilderFactory .newInstance(); DocumentBuilder domBuilder = domFactory.newDocumentBuilder(); Document doc = domBuilder.parse(new File("I:\\test2.xml")); //XPathAPI需要xalan.jar支持 NodeList recordlist=XPathAPI.selectNodeList(doc, "records/record"); PrintWriter pWriter=new PrintWriter("I:\\hello2.csv"); String tempString; NodeList phyNodeList=XPathAPI.selectNodeList(doc, "records/record[1]/field/@lname"); for (int i = 0; i < phyNodeList.getLength(); i++) { tempString=new String(phyNodeList.item(i).getNodeValue().getBytes("UTF-8"),"UTF-8"); if (i==phyNodeList.getLength()-1) { pWriter.print(tempString); }else { pWriter.print(tempString+","); } } pWriter.println(); for(int i=0;i<recordlist.getLength();i++){ NodeList fieldlist=XPathAPI.selectNodeList(recordlist.item(i), "field"); for (int j = 0; j < fieldlist.getLength(); j++) { Element element=(Element)fieldlist.item(j); tempString=new String (element.getFirstChild().getNodeValue().getBytes("UTF-8"),"UTF-8"); if (j==fieldlist.getLength()-1) { pWriter.print(tempString); }else pWriter.print(tempString+","); } pWriter.println(); } pWriter.close(); } }
运行后同样达到预期效果:
