如何将xslt生成的错误消息传递给java应用程序调用者

<xsl:message terminate="yes">
   <xsl:text>Error: Invalid input document.</xsl:text>
</xsl:message>

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;

public class XsltTransformer {
   public static void main(String[] args) {
      try {
         TransformerFactory factory = TransformerFactory.newInstance();
         Transformer transformer = factory.newTransformer(new StreamSource("transform.xsl"));
         transformer.transform(new StreamSource("input.xml"), new StreamResult("output.html"));
      } catch (TransformerException e) {
         // 获取XSLT中定义的错误消息
         String errorMessage = e.getMessage();
         // 处理错误消息
         System.out.println("Error: " + errorMessage);
      }
   }
}
