WCF IDispatchMessageInspector How to fix incoming xml?

Question

In the WCF service, I have implemented the IDispatchMessageInspector interface. In the AfterReceiveRequest method ref Message request - the error "when reading the body: System.Xml.XmlException" comes. This error occurs due to an error in the XML in the request.I can't influence the request.

<data xsi:type="xsd:string"><?xml version="1.0" encoding="utf-8"?>
  <someRequest>
    <Number>Test</Number>
    <Date>2023-01-09T00:00:00</Date>
</someRequest>

I'm trying to fix

request.toString().Replace("<?xml version="1.0" encoding="utf-8"?>" ,"");

Is it possible to get the xml body as text? Tried:

using (var reader = request.GetReaderAtBodyContents())
{
  query string var = reader.ReadContentAsString();
}

var body = request.getBody<string>();

If I implement the IDispatchOperationSelector interface. The method is called before AfterReceiveRequest. But there's also a Message parameter

To read an xml file, you can use XmlDocument.InnerXml to get it :

XmlDocument doc = new XmlDocument();
doc.Load("path to your file");
string xmlcontents = doc.InnerXml;

Or like this:

public string GetXMLAsString(XmlDocument myxml)
    {

        StringWriter sw = new StringWriter();
        XmlTextWriter tx = new XmlTextWriter(sw);
        myxml.WriteTo(tx);

        string str = sw.ToString();// 
        return str;
    }

After getting it, then get rid of what you don't need.
