Web.config transfor is adding 
 How to ignore linebreak during transformation

Question

In my ASP.net web.config I have below configuration

<system.webServer>
  <httpProtocol>
    <customHeaders>
       <add name="Content-Security-Policy-report-only" value="default-src 'none';
            script-src 'self' 'unsafe-inline' 'unsafe-eval' script1;
            img-src 'self' img1;
            style-src 'self' 'unsafe-inline' css1;
            font-src 'self' url2;
            connect-src 'self' url1;
            frame-src 'self';
            report-uri value1" />
     </customHeaders>
  </httpProtocol>
</system.webServer>

In web.dev.config I don't have any transformations related to this XML path. but after transformation, I could see 
 on every line breaks. How to fix this issue?

After transformation output will be like

 <add name="Content-Security-Policy-report-only" value="default-src 'none';&#xD;&#xA;   script-src 'self' 'unsafe-inline' 'unsafe-eval' script1;&#xD;&#xA;  img-src 'self' img1;&#xD;&#xA;  style-src 'self' 'unsafe-inline' css1;&#xD;&#xA;    font-src 'self' url2;&#xD;&#xA; connect-src 'self' url1;&#xD;&#xA;  frame-src 'self';&#xD;&#xA; report-uri value1" />
