Question

我有以下XML文件：

<?xml version="1.0" encoding="utf-8"?>
<Config version="Vs1.00.00"><!-- xmlns="urn:xmldata-schema">-->

<<SystemSettings>
    <Workstation></Workstation>
    <Company></Company>
    <InstallationDate></InstallationDate>
    <SupportContactLine1></SupportContactLine1>
    <SupportContactLine2></SupportContactLine2>
    <SupportContactLine3></SupportContactLine3>
    <UserFile></UserFile>
</SystemSettings>

<Settings>
    <StartUpWorkspace></StartUpWorkspace>
    <StartLanguage></StartLanguage>
    <ExportPath></ExportPath>
    <ImportPath></ImportPath>
    <BackUpRestorePath></BackUpRestorePath>
    <AdjHistoryPath></AdjHistoryPath>
    <TestHistoryPath></TestHistoryPath>
    <LogFilePath></LogFilePath>
</Settings>

<DefaultSettings>
    <DefaultSupportLine1></DefaultSupportLine1>
    <DefaultSupportLine2></DefaultSupportLine2>
    <DefaultSupportLine3></DefaultSupportLine3>
    <DefaultUserFile></DefaultUserFile>
    <DefaultStartUpWorkspace></DefaultStartUpWorkspace>
    <DefaultStartLanguage></DefaultStartLanguage>
    <DefaultWorkspacePath></DefaultWorkspacePath>
    <DefaultExportPath></DefaultExportPath>
    <DefaultImportPath></DefaultImportPath>
    <DefaultBackUpRestorePath></DefaultBackUpRestorePath>
    <DefaultAdjHistoryPath></DefaultAdjHistoryPath>
    <DefaultTestHistoryPath></DefaultTestHistoryPath>
    <DefaultLogFilePath></DefaultLogFilePath>
    <DefaultMasterPassword crypt="No"></DefaultMasterPassword>
    <DefaultLogger></DefaultLogger>
</DefaultSettings>

</Config>

我需要验证另一个XML文件。有没有办法可以检查另一个XML文件，如果它与我的文件具有相同的结构？

Answer 1

您可以创建一个可能看起来像这样的xsd架构。（我推荐@daryal的xml架构，但我会对xml元素施加一些约束。）

<xs:element name="SystemSettings">
<xs:complexType>
  <xs:sequence>
    <xs:element name="Workstation" minOccurs="0" maxOccurs="1" />
    ...
  </xs:sequence>
</xs:complexType>

...

然后您可以使用此代码执行验证

using (var xsdStream = new MemoryStream(fXmlSchema))
        {
            xsdStream .Position = 0;
            using (var xsdReader = XmlReader.Create(xsdStream ))
            {
                XmlReaderSettings settings = new XmlReaderSettings();
                settings.ValidationType = ValidationType.Schema;
                settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
                settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
                settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
                settings.Schemas.Add(XmlSchema.Read(xsdReader , [performingValidationCallback]));

                using (var xmlStream = new MemoryStream(fXml))
                {
                    using (var xmlReader = XmlReader.Create(xmlStream, settings ))
                    {
                        try
                        {
                            xmlStream .Position = 0;
                            while (xmlReader .Read())
                            {
                            }
                        }
                        catch (XmlException e)
                        {
                            //VALIDATIONERROR
                        }
                    }
                }
            }
        }

Answer 2

您需要创建xml scheme，然后使用XDocument.Validate方法检查xml是否符合方案

Answer 3

您需要一个XSD文件来检查xml是否正确。如果您没有xsd文件，某些工具可能会创建xsd from xml，但您可能需要修改创建的xsd。

此answer描述了如何针对XSD文件验证c＃中的xml文件。
