xslt:Saxon中的消息 - 消息在哪里?

标签: xml xslt message saxon

我使用Saxon XSLT版本9.6.0.1。样式表包含以下代码:

...
<xsl:message terminate="yes">errormessage</xsl:message>
...

我的应用程序按预期终止,但有以下异常:

net.sf.saxon.expr.instruct.TerminationException: Processing terminated by xsl:message at line 45 in 
    at net.sf.saxon.expr.instruct.Message.processLeavingTail(Message.java:253)  at net.sf.saxon.expr.instruct.Message.processLeavingTail(Message.java:253)
    at net.sf.saxon.expr.instruct.Choose.processLeavingTail(Choose.java:822)

现在我想知道&#34; errormessage&#34;文字实际上是。我可以在stderr上看到它,但需要将它显示给用户或将其放入日志文件中。

如何以编程方式访问消息文本?

如果您使用Saxon s9api,请参阅撒克逊资源中的示例文件S9APIExampleshttp://saxonica.com/download/download_page.xml处提供),其示例设置为MessageListener:< / p>

        Processor proc = new Processor(false);
        XsltCompiler comp = proc.newXsltCompiler();
        String stylesheet =
                "<xsl:transform version='2.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>\n" +
                        "  <xsl:template name='main'>\n" +
                        "    <xsl:message><msg>Reading http://www.w3.org/TR/xslt20/ ...</msg></xsl:message>/>\n" +
                        "    <exists>\n" +
                        "      <xsl:value-of select=\"doc-available('http://www.w3.org/TR/xslt20/')\"/>\n" +
                        "    </exists>\n" +
                        "    <xsl:message><msg>finishing</msg></xsl:message>\n" +
                        "  </xsl:template>\n" +
                        "</xsl:transform>";
        StringReader reader = new StringReader(stylesheet);
        StreamSource styleSource = new StreamSource(reader, "http://localhost/string");
        XsltExecutable templates = comp.compile(styleSource);
        XsltTransformer transformer = templates.load();
        transformer.setInitialTemplate(new QName("main"));
        transformer.setMessageListener(
                new MessageListener() {
                    public void message(XdmNode content, boolean terminate, SourceLocator locator) {
                        System.err.println("MESSAGE terminate=" + (terminate ? "yes" : "no") + " at " + new Date());
                        System.err.println("From instruction at line " + locator.getLineNumber() +
                                " of " + locator.getSystemId());
                        System.err.println(">>" + content.getStringValue());
                    }
                }
        );
        Serializer out = proc.newSerializer(System.out);
        transformer.setDestination(out);
        transformer.transform();
