Myujth

I have an XMLDocument which i am deserializing into object in my C# code. It works fine until i have nodes like below,

 <Name>ABC</Name>
 <Message>Invalid Name</Message>

In the above scenario what i get inside my C# object would be Name = ABC and Message = Invalid Name.

But now i have a requirement to read a complete XML node inside XMLDocument. Which is like this,

<ReadXML><fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
 <entity name="customerproduct">
 <attribute name="customerproductid" />
 <attribute name="name" />
 <attribute name="createdon" />
 <attribute name="customertype" />
 <attribute name="custodian_customerproductid" />
 <attribute name="accountnumber" />
 <order attribute="name" descending="false" />
 <filter type="and">
 <condition attribute="productgroup" operator="eq" uiname="Credit Cards" uitype="productgroup" value="12344" />
 <condition attribute="customer" operator="eq" uiname="abc xyz" uitype="contact" value="1234" />
 </filter>
 </entity>
 </fetch></ReadXML>

I have an object ReadXML inside my C# code and i was looking to get complete XML that is inside ReadXML node as an string inside my ReadXML variable.

something like this,

string ReadXML = "<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
 <entity name="customerproduct">
 <attribute name="customerproductid" />
 <attribute name="name" />
 <attribute name="createdon" />
 <attribute name="customertype" />
 <attribute name="custodian_customerproductid" />
 <attribute name="accountnumber" />
 <order attribute="name" descending="false" />
 <filter type="and">
 <condition attribute="productgroup" operator="eq" uiname="Credit Cards" uitype="productgroup" value="12344" />
 <condition attribute="customer" operator="eq" uiname="abc xyz" uitype="contact" value="1234" />
 </filter>
 </entity>
 </fetch>"

Inside my Code i am doing this,

 XmlDocument doc = new XmlDocument();

 doc.Load(@"D:DevelopmentFrameworkTestApplicationXMLScriptXMLScriptXMLFile.xml");


 string XML = doc.InnerXml;
 operationTitle.Text = "Stop Lost Card"; ;
 System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(MyOperation));
 MemoryStream memStream = new MemoryStream(Encoding.UTF8.GetBytes(vrp_XML));
 MyOperation = (MyOperation)serializer.Deserialize(memStream);

And Inside MyOperation Class, i have ReadXML like this,

[XmlElement(ElementName = "ReadXML")]
public string ReadXML get; set; 

Whenever i try to read the XML into the string i get the following error,

 System.InvalidOperationException was unhandled
 HResult=-2146233079
 Message=There is an error in XML document (1, 1329).

The problem is that we cannot serialize/deserialize a complex type to string. Instead we can define our own type and implement IXmlSerializable interface to provide our own implementation.

Below I've defined a MyString class to implement the same. In ReadXml method I'm using innerXml. You may use the outerXml as well.

public class MyString : IXmlSerializable

 string _xmlString;
 public XmlSchema GetSchema()
 
 return null;
 

 public void ReadXml(XmlReader reader)
 
 reader.MoveToContent();

 Boolean isEmptyElement = reader.IsEmptyElement;
 if (!isEmptyElement)
 
 _xmlString = reader.ReadInnerXml();
 
 

 public void WriteXml(XmlWriter writer)
 
 writer.WriteString(_xmlString);
 

The property ReadXML will now be of type MyString instead of string.

[XmlElement(ElementName = "ReadXML")]
public MyString ReadXML get; set; 

Ref: I got the idea from the following Stackoverflow question https://stackoverflow.com/a/22106996/643318

var xml=File.ReadAllText(@"D:DevelopmentFrameworkTestApplicationXMLScriptXMLScriptXMLFile.xml")

var xml=File.ReadAllText(@"D:XMLFile.xml");

var xml_l=xml.ToLower();

var ind_1=xml_l.IndexOf("<fetch");
var ind_2=xml_l.IndexOf("</fetch",ind_1);

var xml_fetch=xml.Substring(ind_1, ind_2 - ind_1+8);
