How to save CRLF (/r/n) into '
&#10' - decimal format instead of '
&#xA' -hexadecimal format in XML file from C# application?

Question

The /r/n or the new line is converted in (Hexadecimal) instead of (Decimal) in the Windows production environment in an XML file.
The same code converts /r/n as (Decimal) as required/expected in my local environment.

C# code:

---

*XElement xelm = *******; //Contains xml text with /r/n
XDocument xdoc = new XDocument();
xdoc.add(xelm);
using(var strWriter = new StreamWriter(path, false, new UTF8Encoding(false)))
{
xdoc.Save(strWriter);
}*

---

I tried replacing text containing /r/n into [.Replace("\r\n", " ");] but it is not successful in the production server and saving in hexadecimal format.

Could anyone please suggest a solution where the code saves the data in decimal format ( ) in all the environments?

Answer 1

Both of decimal and hexadecimal representations are valid.

If it is important to have decimal values for some artificial reasons, then maybe consider a custom writer:

using( var w = new MyXmlTextWriter( path, new UTF8Encoding( false ) ) )  
{  
    xdoc.Save( w );  
}  

where MyXmlTextWriter is something like this:

public class MyXmlTextWriter : System.Xml.XmlTextWriter  
{  
    public MyXmlTextWriter( string filename, Encoding? encoding )   
       : base( filename, encoding )  
    {  
    }  
  
    public override void WriteString( string? text )  
    {  
        string[] a = text.Split( "\r\n" );  
  
        for( int i = 0; i < a.Length; i++ )  
        {  
            if( i > 0 )  
            {  
                base.WriteRaw( "&#13;&#10;" );  
            }  
            base.WriteString( a[i] );  
        }  
    }  
}
