命名空间 'http://yyy' 中的子元素 'xxx' 无效，而 xml 中实际上没有额外的命名空间设置

Question

SO 进行了很多类似的讨论，但在查看了大约 5-6 个帖子之后。 None 似乎符合我的情况。根据我的观察，之前的大多数帖子似乎都有额外的命名空间设置导致了问题，但我认为我的情况并非如此。

所以我有一个网络服务将接收以下 xml

<?xml version="1.0" encoding="UTF-8"?>
<ProductBindingReportRequest xmlns="http://schemas.ms.it.oem/digitaldistribution/2010/10" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
   <CustomerBindingUniqueID>FA8E995F-50D2E911-9475-0050560063F7</CustomerBindingUniqueID>
   <SoldToCustomerID>0000064397</SoldToCustomerID>
   <ReceivedFromCustomerID>QACN-CQ</ReceivedFromCustomerID>
   <TotalLineItems>2</TotalLineItems>
   <ProductBindings>
      <ProductBinding>
         <YZProductKeyID>3423553504516</YZProductKeyID>
         <XYSpecifics>
            <XYSerialNumber>5CD936C2FW</XYSerialNumber>
            <ConsumedDate>9/8/2019 3:47:37 PM</ConsumedDate>
         </XYSpecifics>
         <ServiceProductKeyID>4020124189204</ServiceProductKeyID>
      </ProductBinding>
      <ProductBinding>
         <YZProductKeyID>3423553504661</YZProductKeyID>
         <XYSpecifics>
            <XYSerialNumber>5CD936C1KK</XYSerialNumber>
            <ConsumedDate>9/8/2019 3:47:55 PM</ConsumedDate>
         </XYSpecifics>
         <ServiceProductKeyID>4020124189205</ServiceProductKeyID>
      </ProductBinding>
   </ProductBindings>
   <XYSpecifics>
      <SiteIdentifier>QACN-CQ</SiteIdentifier>
   </XYSpecifics>
</ProductBindingReportRequest>

我们需要验证 xml 输入，因此基于上面的 xml 我创建了以下 xsd

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <xsd:element name="ProductBindingReportRequest">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="CustomerBindingUniqueID" type="xsd:string" />
        <xsd:element name="SoldToCustomerID" type="xsd:unsignedShort" />
        <xsd:element name="ReceivedFromCustomerID" type="xsd:string" />
        <xsd:element name="TotalLineItems" type="xsd:unsignedByte" />
        <xsd:element name="ProductBindings">
          <xsd:complexType>
            <xsd:sequence>
              <xsd:element maxOccurs="unbounded" name="ProductBinding">
                <xsd:complexType>
                  <xsd:sequence>
                    <xsd:element name="YZProductKeyID" type="xsd:unsignedLong" />
                    <xsd:element name="XYSpecifics">
                      <xsd:complexType>
                        <xsd:sequence>
                          <xsd:element name="XYSerialNumber" type="xsd:string" />
                          <xsd:element name="ConsumedDate" type="xsd:string" />
                        </xsd:sequence>
                      </xsd:complexType>
                    </xsd:element>
                    <xsd:element name="ServiceProductKeyID" type="xsd:unsignedLong" />
                  </xsd:sequence>
                </xsd:complexType>
              </xsd:element>
            </xsd:sequence>
          </xsd:complexType>
        </xsd:element>
        <xsd:element name="XYSpecifics">
          <xsd:complexType>
            <xsd:sequence>
              <xsd:element name="SiteIdentifier" type="xsd:string" />
            </xsd:sequence>
          </xsd:complexType>
        </xsd:element>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
</xsd:schema>

然后我们通过下面的方法xsd验证xml

public static bool ValidateXML(string strXML, string strSchemePath, string strXMLSchemeName, ref string strException)
{
    if (strSchemePath.Substring(strSchemePath.Length - 1) != "\")
        strSchemePath = strSchemePath + "\";

    try
    {
        XmlReaderSettings settings = new XmlReaderSettings();
        settings.Schemas.Add("http://schemas.ms.it.oem/digitaldistribution/2010/10", strSchemePath + strXMLSchemeName);
        settings.ValidationType = ValidationType.Schema;
        XmlReader readerCheck = XmlReader.Create(new StringReader(strXML), settings);
        XmlDocument checkXmlDocument = new XmlDocument();
        checkXmlDocument.Load(readerCheck);
        checkXmlDocument.RemoveAll();
        return true;
    }
    catch (Exception ex)
    {
        strException = ex.ToString();
        return false;
    }
}

收到的大多数 xml 都可以在相同的实现下正常工作，但上面的组合给了我

The element 'XYSpecifics' in namespace 'http://schemas.ms.it.oem/digitaldistribution/2010/10' has invalid child element 'SiteIdentifier' in namespace 'http://schemas.ms.it.oem/digitaldistribution/2010/10'.

我的问题是

是因为 XYSpecifics 存在于 ProductBindings?
有什么方法可以调整 xsd 以使验证有效吗？

Answer 1

我不太清楚

settings.Schemas.Add("http://schemas.ms.it.oem/digitaldistribution/2010/10", strSchemePath + strXMLSchemeName);

对 XML reader 实例有效，但您也可以在 XML 架构文档本身中包含此命名空间：

XML 架构

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://schemas.ms.it.oem/digitaldistribution/2010/10">
    <xsd:element name="ProductBindingReportRequest">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element name="CustomerBindingUniqueID" type="xsd:string" />
                <xsd:element name="SoldToCustomerID" type="xsd:unsignedShort" />
                <xsd:element name="ReceivedFromCustomerID" type="xsd:string" />
                <xsd:element name="TotalLineItems" type="xsd:unsignedByte" />
                <xsd:element name="ProductBindings">
                    <xsd:complexType>
                        <xsd:sequence>
                            <xsd:element maxOccurs="unbounded" name="ProductBinding">
                                <xsd:complexType>
                                    <xsd:sequence>
                                        <xsd:element name="YZProductKeyID" type="xsd:unsignedLong" />
                                        <xsd:element name="XYSpecifics">
                                            <xsd:complexType>
                                                <xsd:sequence>
                                                    <xsd:element name="XYSerialNumber" type="xsd:string" />
                                                    <xsd:element name="ConsumedDate" type="xsd:string" />
                                                </xsd:sequence>
                                            </xsd:complexType>
                                        </xsd:element>
                                        <xsd:element name="ServiceProductKeyID" type="xsd:unsignedLong" />
                                    </xsd:sequence>
                                </xsd:complexType>
                            </xsd:element>
                        </xsd:sequence>
                    </xsd:complexType>
                </xsd:element>
                <xsd:element name="XYSpecifics">
                    <xsd:complexType>
                        <xsd:sequence>
                            <xsd:element name="SiteIdentifier" type="xsd:string" />
                        </xsd:sequence>
                    </xsd:complexType>
                </xsd:element>
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>
</xsd:schema>

这应该可行，尽管元素 XYSpecifics 在此架构中定义了两次，但具有不同的子元素，这有点不幸。编写模式的更好方法是一次定义此类型。例如：

XML 架构（改进）

Answer 2

您编写了一个模式来验证不在命名空间中的元素。您需要为命名空间“http://schemas.ms.it.oem/digitaldistribution/2010/10”中的元素编写一个模式，您可以通过在 xs:schema 元素上设置 targetNamespace 属性来实现。这必须在架构本身中完成，不能在验证中完成 API.

命名空间 'http://yyy' 中的子元素 'xxx' 无效，而 xml 中实际上没有额外的命名空间设置

Invalid child element 'xxx' in namespace 'http://yyy' while there is actually no extra namespace setting in xml

c#

xml

xsd
