Problem with Serialization/Deserialization an XML containing CDATA attribute

问题

I need to deserialize/serialize the xml file below:

<items att1="val">
<item att1="image1.jpg">
         <![CDATA[<strong>Image 1</strong>]]>
</item>
<item att1="image2.jpg">
         <![CDATA[<strong>Image 2</strong>]]>
</item>     
</items>

my C# classes:

[Serializable]
[XmlRoot("items")]    
public class RootClass
{
  [XmlAttribute("att1")]
  public string Att1 {set; get;}

  [XmlElement("item")]  
  public Item[] ArrayOfItem {get; set;}
}

  [Serializable]
public class Item
{
    [XmlAttribute("att1")]
    public string Att1 { get; set; }

    [XmlText]
    public string Content { get; set; }
}

and everything works almost perfect but after deserialization in place

<![CDATA[<strong>Image 1</strong>]]>

I have

&lt;strong&gt;Image 1&lt;/strong&gt;

I was trying to use XmlCDataSection as type for Content property but this type is not allowed with XmlText attribute. Unfortunately I can't change XML structure.

How can I solve this issue?

回答1:

this should help

    private string content;

    [XmlText]
    public string Content
    {
        get { return content; }
        set { content = XElement.Parse(value).Value; }
    }

回答3:

First declare a property as XmlCDataSection

public XmlCDataSection ProjectXml { get; set; }

in this case projectXml is a string xml

ProjectXml = new XmlDocument().CreateCDataSection(projectXml);

when you serialize your message you will have your nice format (notice )

<?xml version="1.0" encoding="utf-16"?>
<MessageBase xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xsi:type="Message_ProjectStatusChanged">

Most of the solutions presented in StackOverflow works only for Serialization, and not Deserialization. This one will do the job, and if you need to get/set the value from your code, use the extra property PriceUrlByString that I added.

    private XmlNode _priceUrl;
    [XmlElement("price_url")]
    public XmlNode PriceUrl
    {
        get
        {
            return _priceUrl;
        }
        set
        {
            _priceUrl = value;
        }
    }

    [XmlIgnore]
    public string PriceUrlByString
    {
        get
        {
            // Retrieves the content of the encapsulated CDATA
            return _priceUrl.Value;
        }

        set
        {
            // Encapsulate in a CDATA XmlNode
            XmlDocument xmlDocument = new XmlDocument();
            this._priceUrl = xmlDocument.CreateCDataSection(value);
        }
    }
