以字符串形式获取 Saxon XsltTransformer.Run() 结果答案

【问题标题】：Get Saxon XsltTransformer.Run() Result as String以字符串形式获取 Saxon XsltTransformer.Run() 结果
【发布时间】：2014-01-20 14:47:25
【问题描述】：

我对 Saxon XsltTransformer 类的问题是；

我正在测试 Saxon .NET 示例，根据最后一个 WriteLine() 方法的输出，下面的示例代码应将验证/转换结果打印到文件 (outfile)，但始终将结果重定向到标准输出并且文件始终为空。

我的问题是如何将 Xslt 验证/转换结果作为 string、MemoryStream 等...我的主要目的是进行这些交易（XsltTransformer.Run() 和其他要求事务并获取结果）在内存中（无需在磁盘上创建任何文件）。

我会尝试使用 memorystream 进行相同的事务以将结果作为字符串（磁盘上没有文件）但我没有将结果作为文件。而我在这里……

.NET 版本：4.5

Saxon API 版本：SaxonHE9.5N

感谢您的回答，对不起我的英语。

    Uri schemaUri = new Uri(@"file:\\C:\path\to\my.xml");
    Uri xslUri    = new Uri(@"file:\\C:\path\to\my.xsl");
    // Create a Processor instance.
    Processor processor = new Processor();

    // Load the source document
    XdmNode input = processor.NewDocumentBuilder().Build(schemaUri);

    // Create a transformer for the stylesheet.
    XsltTransformer transformer = processor.NewXsltCompiler().Compile(xslUri).Load();

    // Set the root node of the source document to be the initial context node
    transformer.InitialContextNode = input;

    // Create a serializer
    String outfile = "OutputFromXsltSimple2.xml";
    Serializer serializer = new Serializer();
    FileStream fs = new FileStream(outfile, FileMode.Create, FileAccess.Write);
    serializer.SetOutputStream(fs);

    // Transform the source XML to System.out.
    transformer.Run(serializer);
    //fs.Flush();
    //fs.Close();

    Console.WriteLine("\nOutput written to " + outfile + "\n");

更新： 在 Java 方面，我正在使用此代码块执行此操作；

TransformerFactory tfactory = TransformerFactory.newInstance();

Transformer transformer = tfactory.newTransformer(new StreamSource("/path/to/my.xsl"));


StreamResult sr = new StreamResult();
StringWriter sw = new StringWriter();
sr.setSystemId("DENEMME");

transformer.transform(new StreamSource("/path/to/my.xml"), sr);

System.out.println("----------------");
System.out.println(sw.getBuffer().toString());

在 XSL 中，对 XML 节点值或属性值进行数据验证。如果根据 XSL 有任何无效值，则 StreamResult 中收集的所有错误消息。

我也在为 Java 和 .NET 使用 Saxon XSLT API。但是当我在 .NET 端执行工作 Java 示例时，示例 App 抛出异常；

提供者 com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl 没找到。

所以我正在尝试 C# 的第一个示例代码。

对于 xsl 文件，我组合了这 3 个 XML 文件并将这个组合的 xml 提供给 Oxygen XML 编辑器，我使用 XSL 文件，即 Oxygen 编辑器的输出作为我的组合 xml。（氧气编辑器忽略了第二个 XML 的包含语句，所以我手动将所有 XML 文件合并为一个 XML 文件）。

解决了 Michael Kay 的答案

简单地写了这个类：

public void Message(XdmNode content, bool terminate, IXmlLocation location) {
    //System.Console.WriteLine("content: " + content.BaseUri);
    System.Console.WriteLine("content: " + content.Count);
    System.Console.WriteLine("content: " + content.NodeKind.ToString());
    System.Console.WriteLine("content: " + content.StringValue);
    System.Console.WriteLine("content: " + content.OuterXml);

    System.Console.WriteLine("----------------------------------------");

    System.Console.WriteLine("terminate: " + terminate);

    System.Console.WriteLine("----------------------------------------");

    System.Console.WriteLine("terminate: " + location.BaseUri);
    System.Console.WriteLine("terminate: " + location.LineNumber);


    System.Console.WriteLine("----------------------------------------");
    System.Console.WriteLine("----------------------------------------");
    System.Console.WriteLine("----------------------------------------");
    System.Console.WriteLine("----------------------------------------");
    System.Console.WriteLine("----------------------------------------");

}

然后试试；

MyMessageListener myMessageListener = new MyMessageListener();
transformer.MessageListener = myMessageListener;

MessageListener 类可以处理验证错误消息。

【问题讨论】：

另请注意，URI 仅使用正斜杠，因此应为 new Uri(@"file:///C:/path/to/my.xml"); 等。

标签： c# .net xslt saxon

【解决方案1】：

可以通过在 XsltTransformer 对象上设置 MessageListener 属性来重定向 xsl:message 的输出。您需要实现 IMessageListener 接口，它有一个方法 Message()。消息的内容作为 XdmNode 提供；如果您的消息是一个简单的字符串（而不是结构化的 XML），那么您可以简单地使用该节点的 StringValue 属性来获取消息内容。

我怀疑主要结果树为空的原因是您没有向其写入任何内容；也就是说，您唯一的输出是 xsl:message 输出。如果没有看到您的完整样式表，我无法确认这一点。

【讨论】：

正如我所说，我的主要目的是使用 schematron 验证 XML 的值。为此，我有 3 个 xml 文件，其中包含 XML 值的验证规则。我不知道我应该怎么做。我从这 3 个 xml 创建了一个 xsl 文件（通过 Oxygen XML 编辑器）。使用这个 XSL 文件，我可以在 Java 中验证 XML（您可以在第一篇文章中看到示例代码），但 .NET 会出错。完整的场景是这样的；使用给定的 3 个 xml 文件对 XML 文件进行 schematron 验证。我将更新第一篇文章以显示 xml 文件内容（schamtron 验证 xml 文件）和由 Oxygen XML 编辑器使用这些 xml 文件创建的 xsl 文件。
（验证规则函数包含 XSLT 2.0，这就是我尝试使用 Saxon API 进行此操作的原因）。
谢谢，MessageListener 是我想要的，我更新了我的第一篇文章以获得答案。还有一个问题；有没有简单的方法可以根据给定的其他 3 个 XML 文件对 XML 文件进行 schematron 验证。这是正确的方法吗？ 1- 从验证 XML 文件创建一个 XSL 文件；为此使用 3. 派对应用程序，如 Oxygen XML 编辑器等 2-) 使用 3. 派对 API，如撒克逊人。 .NET 中是否有任何本机方式。每一步都需要（手动）干预。对于第 1 步；将 3 个文件合并为一个 XML 文件（输入）并修复氧气输出的错误表达式。第2步;写 MessageListener vs...
这似乎是一个完全不相关的问题。从零开始。
@sem 你有没有找到一种简单的方法来验证 xml 文件？并且还可以在网络核心上工作？ :)
