Question

我使用Microsoft SDK中的xsd.exe首先生成xml文件的模式，然后生成以前生成的xsd文件的C＃文件。这是我的xml文件：

<event topic="event.system.visualization.initialization.response" subject="CIBEK204Test0" producer="de.cibek.configurator" timeToLive="0" too="1351252459919" duration="0">
<payload>
    <![CDATA[
        <?xml version="1.0" encoding="UTF-8" standalone="no"?>
            <building>
                <floor name="">
                    <location name="Wohnen">
                        <item category="event.environment.apartment.window" groupaddress="10248" location="Wohnen" location.floor="" location.specification="Mitte links"/>
                    </location>
                </floor>
            </building>
    ]]>
</payload>
<properties/>
<traces/>

现在生成的xsd：

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xs:element name="event">
 <xs:complexType>
  <xs:sequence>
    <xs:element name="payload" type="xs:string" minOccurs="0" msdata:Ordinal="0" />
    <xs:element name="properties" type="xs:string" minOccurs="0" msdata:Ordinal="1" />
    <xs:element name="traces" type="xs:string" minOccurs="0" msdata:Ordinal="2" />
  </xs:sequence>
  <xs:attribute name="topic" type="xs:string" />
  <xs:attribute name="subject" type="xs:string" />
  <xs:attribute name="producer" type="xs:string" />
  <xs:attribute name="timeToLive" type="xs:string" />
  <xs:attribute name="too" type="xs:string" />
  <xs:attribute name="duration" type="xs:string" />
 </xs:complexType>
 </xs:element>
 <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
  <xs:complexType>
  <xs:choice minOccurs="0" maxOccurs="unbounded">
    <xs:element ref="event" />
  </xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>

现在我的问题是：为什么xsd.exe会忽略CDATA中的嵌入式xml代码？是否有可能强制xsd.exe不忽略CDATA？或者是否可以生成2个xsd和cs文件，并告诉第一个（其中有事件）有一个CDATA节点，其中有另一个xml文件并将其链接到生成的代码中？

对不起，我希望任何人都可以帮助我:)

Answer 1

如果使用CDATA，解析器将忽略CDATA部分内的所有内容。如果您的目标是获取CDATA内的部分，请点击此链接。

Answer 2

我使用xsd.exe和以下xsd文件成功反序列化CDATA：

<xs:element name="event">
  <xs:complexType>
    <xs:sequence>
      <xs:element ref="payload" minOccurs="0" maxOccurs="unbounded" />
    </xs:sequence>
  </xs:complexType>
</xs:element>

<xs:element name="payload">
  <xs:complexType>
    <xs:simpleContent>
      <xs:extension base="xs:string"/>
    </xs:simpleContent>
  </xs:complexType>
</xs:element>

xsd.exe生成的代码是：

/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.17929")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]

[System.Xml.Serialization.XmlRootAttribute(Namespace="", IsNullable=false)]
public partial class @event {

    private payload[] payloadField;

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("payload")]
    public payload[] payload {
        get {
            return this.payloadField;
        }
        set {
            this.payloadField = value;
        }
    }
}

/// <remarks/>

[System.Xml.Serialization.XmlRootAttribute(Namespace="", IsNullable=false)]
public partial class payload {

    private string valueField;

    /// <remarks/>
    [System.Xml.Serialization.XmlTextAttribute()]
    public string Value {
        get {
            return this.valueField;
        }
        set {
            this.valueField = value;
        }
    }
}

使用XmlSerializer.Deserialize使用CData填充payload.Value

xsd.exe忽略cdata？
