通过 XSD 文件验证 XML 节点 [英] validating XML node over a XSD file

问题描述

我正在尝试根据 XML 架构验证 XML 节点或片段.我已经阅读了这篇文章:

I'm trying to validate XML nodes or fragments against an XML schema. I have read this article:

验证 xml 节点，而不是整个文档

但所选择的解决方案似乎不适合我.

but the chosen solution doesn't look like to work for me.

private void ValidateSubnode(XmlNode node, XmlSchema schema)
{
  XmlTextReader reader = new XmlTextReader(node.OuterXml, XmlNodeType.Element, null);

  XmlReaderSettings settings = new XmlReaderSettings();
  settings.ConformanceLevel = ConformanceLevel.Fragment;
  settings.Schemas.Add(schema);
  settings.ValidationType = ValidationType.Schema;
  settings.ValidationEventHandler += new ValidationEventHandler(XSDValidationEventHandler);

  XmlReader validationReader = XmlReader.Create(reader, settings);

  while (validationReader.Read())
  {
  }
}

private void XSDValidationEventHandler(object sender, ValidationEventArgs args)
{
  errors.AppendFormat("XSD - Severity {0} - {1}", 
                  args.Severity.ToString(), args.Message);
}

据我所知，验证完整文档的代码是ConformanceLevel.Fragment"

wich is, as far as I can see, the code for validate a full document, but with "ConformanceLevel.Fragment"

例如，有一个像这样简单的模式:

Thus, for example, having a schema as simple as this:

<xsd:schema xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
<xsd:element name="Customer">
  <xsd:complexType>
    <xsd:sequence>
      <xsd:element name="Address">
        <xsd:complexType>
          <xsd:sequence>
            <xsd:element name="Line1" type="xsd:string" />
            <xsd:element name="Line2" type="xsd:string" />
          </xsd:sequence>
       </xsd:complexType>
      </xsd:element>
    </xsd:sequence>
  </xsd:complexType>
</xsd:element>
</xsd:schema>

根"节点验证 OK

<Customer>
  <Address>
    <Line1>Foo</Line1>
    <Line2>Foo2</Line2>
  </Address>
</Customer>

但任何内部节点都不会验证

But any inner node doesn't validate

  <Address>
    <Line1>Foo</Line1>
    <Line2>Foo2</Line2>
  </Address>

我收到错误消息:'Address' 元素未声明"

I receive the error: "'Address' element is not declared"

有什么我遗漏的吗?

推荐答案

在 MiMo 的推荐下，为了解决这个问题我在 RUNTIME 修改了 schema.我将其加载到内存中并在那里进行更改.我在这里发布了我的解决方案:

Following the recomendation of MiMo, to solve the problem I modify IN RUNTIME the schema. I load it in memory and change it there. I posted my solution here:
