作为一名拥有大量 XML 消费和生产经验的开发人员，我以前从未真正与模式进行过交互。这是我第一次真正发生这种情况。

我遇到了一个“功能”，我认为它更像是一个有据可查的错误。

使用 XDocument.Validate() 时，似乎在某些情况下，如果文档与指定的架构不匹配，则文档将有效。我觉得这很可能是我对 XSD、XML 名称空间和预期验证过程之间关系的理解存在缺陷。

因此，我向您提交了我的 XML 示例、我的 XSD 示例和我的验证代码。

XML - 这是故意错误的文档。

<?xml version="1.0" encoding="utf-8" ?>
<SuppliesDefinitions 
  xmlns="http://lavendersoftware.org/schemas/SteamGame/Data/Xml/Supplies.xsd">
  <Supply type="Common">
    <Information/>
    <Ritual/>
    <Weapon/>
    <Tool count="1"/>
    <Tool count="2"/>
    <Tool count="3"/>
  </Supply>
  <Supply type="Uncommon">
    <Information/>
    <Weapon/>
    <Tool count="1"/>
    <Tool count="2"/>
    <Tool count="3"/>
    <Tool count="4"/>
  </Supply>
  <Supply type="Rare">
    <Information/>
    <Rune/>
    <Weapon/>
    <Tool count="2"/>
    <Tool count="3"/>
    <Tool count="4"/>
  </Supply>
</SuppliesDefinitions>

XSD 用于验证它。（同样，这故意是上述 XML 的错误文档）

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="Encounters"
    targetNamespace="http://lavendersoftware.org/schemas/SteamGame/Data/Xml/Encounters.xsd"
    elementFormDefault="qualified"
    xmlns="http://lavendersoftware.org/schemas/SteamGame/Data/Xml/Encounters.xsd"
    xmlns:mstns="http://lavendersoftware.org/schemas/SteamGame/Data/Xml/Encounters.xsd"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
>
  <xs:complexType name="ToolType">
    <xs:attribute name="count" use="required" type="xs:int"/>
  </xs:complexType>

  <xs:complexType name="TaskType">
    <xs:choice maxOccurs="unbounded" minOccurs="1">
      <xs:element name="Weapon"/>
      <xs:element name="Information"/>
      <xs:element name="Tool" type="ToolType"/>
      <xs:element name="Ritual"/>
    </xs:choice>
  </xs:complexType>


  <xs:complexType name="EncounterType">
    <xs:sequence maxOccurs="unbounded" minOccurs="1">
      <xs:element name="Task" type="TaskType"/>
    </xs:sequence>
    <xs:attribute name="name" use="required" type="xs:string"/>
  </xs:complexType>

  <xs:element name="EncounterDefinitions">
    <xs:complexType>
      <xs:sequence maxOccurs="unbounded" minOccurs="1">
        <xs:element name="Encounter" type="EncounterType"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

最后是验证码。

    private static void ValidateDocument(XDocument doc)
    {
        XmlSchemaSet schemas = new XmlSchemaSet();
        schemas.Add(null, XmlReader.Create(new StreamReader(XmlSchemaProvider.GetSchemaStream("Encounters.xsd"))));

        doc.Validate(schemas, (o, e) =>
        {
            //This is never hit!
            Console.WriteLine("{0}", e.Message);
            Assert.False(e.Severity == XmlSeverityType.Error);
        });
    }

我想知道是否有人可以解释我做错了什么。我觉得我对这应该工作的方式做出了一些不正确的假设。在我看来，对一个完全不相关的 XML 文档使用一个 xsd 是无效的。

There is no nodes in your XML that can be validated by the schema (namespaces are different). As result it does not report any errors. As far as I know behavior for nodes that are not matched to any schema is allow anything.

You also could set validation options in XmlReaderSettings to allow warnings:

ReportValidationWarnings - Indicates that events should be reported if a validation warning occurs. A warning is typically issued when there is no DTD or XML Schema to validate a particular element or attribute against. The ValidationEventHandler is used for notification.

Check out XmlSchemaSet.Add and HOW TO: Validate an XML Document by Using Multiple Schemas if you expect nodes from multiple namespaces to be present in the XML.
