c# - 如何使用 C# 根据 HR-XML 验证 XML 文件

Question

我正在寻找一些验证 HR-XML 的建议和指导。

我已经编写了生成 XML 文件的代码，该文件“应该”被正确格式化为 HR-XML，但我想在编写之前使用代码对其进行验证到磁盘。

下面是我的验证方法和验证错误事件处理程序的代码示例

/// <summary>
/// Validate the populated XML
/// </summary>
/// <remarks>
/// The schema folder needs to be "HR-XML-3_0" which contains the "org_hr-xml" and "org_openapplications_platform" folders
/// </remarks>
/// <param name="schemaPath">The root path for the HR-XML XSD files for the xml to be validated against</param>
/// <returns>true if the xml is valid, else false</returns>
public bool Validate(string schemaPath)
{
    try
    {
        // Initalise the valid flag
        this.m_FormatValid = false;
        this.m_ValidationErrors.Clear();

        // Check if there is anything to output
        if (this.m_Root.HasElements == true)
        {
            // Validate that the root node has been populated correctly
            XDocument doc = new XDocument(m_Root);

            XmlSchemaSet schemas = new XmlSchemaSet();

            // Add the schemas in the specified folder to the schema set
            schemas.Add(XmlSchema.Read(new StreamReader(Path.Combine(schemaPath, @"org_hr-xml\3_0\Developer\BODs\RespondHRMasterData.xsd")), null));
            schemas.Add(XmlSchema.Read(new StreamReader(Path.Combine(schemaPath, @"org_openapplications_platform\1_1\Common\OAGi\Components\Meta.xsd")), null));

            // Set the valid flag to true prior to validation and let the event handler set it to false if it's not valid
            this.m_FormatValid = true;

            doc.Validate(schemas, HRXML_Validation_Error);
        }
        else
        {
            Log.WriteLine(Category.Info, "No HR-XML data to validate");
        }
    }
    catch (Exception ex)
    {
        this.m_FormatValid = false;
        Log.WriteLine(Category.Warning, "An error was detected whilst validating HR-XML data", ex);
    }

    return this.m_FormatValid;
}



/// <summary>
/// Event handler for XML validation errors
/// </summary>
void HRXML_Validation_Error(Object source, ValidationEventArgs args)
{
    // There is no need to worry about the severity of the validation as they should always be errors
    // The warning appears only to be triggered is no schema has been specified which shouyldn't be the case here

    // Output the message to the validation list
    this.m_ValidationErrors.Add( args.Message );

    //Set the Valid flag to false
    m_FormatValid = false;
}

我将用于响应 HRMasrterData 请求的 BOD 添加到架构集中，但是由于 RespondHRMasterData.xsd 文件中引用的导入架构，这会生成异常。错误是未定义的复杂类型“http://www.openapplications.org/oagis/9:BusinessObjectDocumentType”用作复杂类型扩展的基础。

将第二个文件添加到模式集中解决了第一个异常并给出了这个异常。类型“http://www.openapplications.org/oagis/9:NormalizedStringType”未声明，或者不是简单类型。

我不该做的是在创建的文件出现“实际”错误之前添加所有 HR-XML 模式文件(除非我真的必须这样做)。

我走在正确的轨道上还是有更好的方法？

谢谢。

Answer 1

我发现验证 HR-XML 的最佳方法是将节点 xsi:schemaLocation 添加到生成的指向所需 BOD 的 xml。

也可以创建一个引用了所有架构文件的 XML Spy 项目。如果这样做，则不需要架构位置。
