我正在使用 xalan 2.7.1 使用 xslt 样式表验证我的 xml 文档。它适用于第一个文档,并通过使用 NodeInfo.lineNumber 和 NodeInfo.columnNumber 扩展名在出错的情况下返回错误消息以及 xml 源的正确行号和列号。
问题是当我尝试重用转换器来验证其他 xml 文档时,它成功地转换了文档,但对于所有错误总是返回 lineNumber=columnNumber=-1。
任何的想法?
编辑:这是我的代码::
package mycompany;
import java.io.File;
import javax.xml.transform.ErrorListener;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import org.apache.xalan.processor.TransformerFactoryImpl;
public class XsltTransformer {
public static void main(String[] args) {
TransformerFactory tFactory = TransformerFactory.newInstance();
tFactory.setAttribute(TransformerFactoryImpl.FEATURE_SOURCE_LOCATION, Boolean.TRUE);
StreamSource xsltStreamSource = new StreamSource(new File("E:\\Temp\\Test\\myXslt.xsl"));
try {
Transformer transformer = tFactory.newTransformer(xsltStreamSource);
File srcFolder = new File("E:\\Temp\\Test");
for (File file : srcFolder.listFiles()) {
if (file.getName().endsWith("xml")) {
Source source = new StreamSource(file);
StreamResult result = new StreamResult(System.out);
XsltTransformer xsltTransformer = new XsltTransformer();
ErrorListenerImpl errorHandler = xsltTransformer.new ErrorListenerImpl();
transformer.setErrorListener(errorHandler);
transformer.transform(source, result);
if (errorHandler.e != null) {
System.out.println("Transformation Exception: " + errorHandler.e.getMessage());
}
transformer.reset();
}
}
} catch (TransformerException e) {
e.printStackTrace();
}
}
private class ErrorListenerImpl implements ErrorListener {
public TransformerException e = null;
public void error(TransformerException exception) {
this.e = exception;
}
public void fatalError(TransformerException exception) {
this.e = exception;
}
public void warning(TransformerException exception) {
this.e = exception;
}
}
}
