这是一个有效的示例，
data.xml包含您的数据：
import java.io.File;import javax.xml.parsers.documentBuilder;import javax.xml.parsers.documentBuilderFactory;import javax.xml.transform.Result;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 javax.xml.transform.stream.StreamSource;import org.w3c.dom.document;class Xml2Csv { public static void main(String args[]) throws Exception { File stylesheet = new File("src/main/resources/style.xsl"); File xmlSource = new File("src/main/resources/data.xml"); documentBuilderFactory factory = documentBuilderFactory.newInstance(); documentBuilder builder = factory.newdocumentBuilder(); document document = builder.parse(xmlSource); StreamSource stylesource = new StreamSource(stylesheet); Transformer transformer = TransformerFactory.newInstance() .newTransformer(stylesource); Source source = new DOMSource(document); Result outputTarget = new StreamResult(new File("/tmp/x.csv")); transformer.transform(source, outputTarget); }}style.xsl
