我们目前正在用 C# 构建一个绿地应用程序。我们有大量使用 Selenium Web 驱动程序的 UI 测试。这些测试（以及单元测试）由我们的 CI 服务器运行。

Selenium 公开了一个 .PageSource 属性，并且（对我而言）通过 HTML5 验证器运行该源代码作为每个 UI 测试的另一部分是有意义的。

我想了解与http://validator.w3.org/相同的内容。作为奖励，我还想了解 508 问题。

我的问题是我找不到任何可以在本地执行此操作并且很容易集成到我的 UI 测试中的东西。W3C 站点公开了一个 SOAP api，但是我不想在 CI 过程中访问他们的站点. 它们似乎也不支持返回 SOAP 响应。我想避免在本地安装完整的 W3C 服务器。

我看到的最接近的是这个http://www.totalvalidator.com/，使用它需要编写临时文件和解析报告。

在我走这条路之前，我想我会看看是否有人知道另一种方法。最好是我可以调用的 DotNet 程序集。

在这个问题上花了整个周末之后，我能看到的唯一解决方案是一个名为 CSE HTML Validator 的商业库

它位于此处http://www.htmlvalidator.com/htmldownload.html

我为它写了一个简单的包装器。这是代码

        OtherMessages = new List<ValidationResult>();

    }

最好的 HTML5 验证器nu checker是用 Java 编写的，很难与 .NET 交互。但是可以将libtidy写入 C++ dll 以从托管代码中调用。他们发布的示例程序对我来说做得很好，有点适应。

LibTidy.h：

public ref class LibTidy
{
public:
    System::String^ __clrcall Test(System::String^ input);
};

LibTidy.cpp：

System::String^ __clrcall LibTidy::Test(System::String^ input)
{
    CStringW cstring(input);
  
    const size_t newsizew = (cstring.GetLength() + 1) * 2;
    char* nstringw = new char[newsizew];
    size_t convertedCharsw = 0;
    wcstombs_s(&convertedCharsw, nstringw, newsizew, cstring, _TRUNCATE);

        TidyBuffer errbuf = { 0 };
        int rc = -1;
        Bool ok;

        TidyDoc tdoc = tidyCreate();                     // Initialize "document"
                
        ok = tidyOptSetBool(tdoc, TidyShowInfo, no);
        ok = tidyOptSetBool(tdoc, TidyQuiet, yes);
        ok = tidyOptSetBool(tdoc, TidyEmacs, yes);
        if (ok)
            rc = tidySetErrorBuffer(tdoc, &errbuf);      // Capture diagnostics
        if (rc >= 0)
            rc = tidyParseString(tdoc, nstringw);           // Parse the input
        if (rc >= 0)
            rc = tidyCleanAndRepair(tdoc);               // Tidy it up!
        if (rc >= 0)
            rc = tidyRunDiagnostics(tdoc);               // Kvetch
        char* outputBytes = (char*)errbuf.bp;
    
        if (errbuf.allocator != NULL) tidyBufFree(&errbuf);
        tidyRelease(tdoc);

        return gcnew System::String(outputBytes);
    }

看起来这个链接可能有你想要的：Automated W3C Validation

您可以在接受的答案中下载标记验证器并将您的 HTML 传递给它。抱歉，它们不是 .NET 程序集：/，但如果你真的想的话，你可以将它包装在 DLL 中。

此外，关于这个问题的答案之一表明 W3C 服务实际上公开了一个 RESTful API，但可以返回一个 SOAP 响应：我如何在我的 .NET 应用程序中使用 W3C 标记验证器 API？
