I used App_start to declare XslCompiledTransform and load data. I wanna to use another function(x) to Transform.
because x will be called several times. I don't want to put line ConfirmedAddrTransform.Load(xsltUri) in the X function.
How can I make that work
  
       protected void Application_Start(Object sender, EventArgs e)
       {
           XslCompiledTransform ConfirmedAddrTransform = new XslCompiledTransform();
           string xsltUri = "http://localhost" + HttpContext.Current.Request.ApplicationPath + "/LocationData.xsl";
           ConfirmedAddrTransform.Load(xsltUri);
              
    }
protected void X()
{
    StringBuilder sbResult = new StringBuilder();
    XmlTextWriter sXML = new XmlTextWriter(new StringWriter(sbResult));
    
    ConfirmedAddrTransform.Transform(_XMLReader, xslArgs, sXML);

}

Thanks

Please make the highlighted changes and it should work:

     protected void Application_Start(Object sender, EventArgs e)
         {
           XslCompiledTransform ConfirmedAddrTransform = new XslCompiledTransform();
           string xsltUri = "http://localhost" + HttpContext.Current.Request.ApplicationPath + "/LocationData.xsl";
           ConfirmedAddrTransform.Load(xsltUri);

HttpContext.Current.Cache["Transform"]= ConfirmedAddrTransform

}
protected void X()
{
    StringBuilder sbResult = new StringBuilder();
    XmlTextWriter sXML = new XmlTextWriter(new StringWriter(sbResult)); 
    XslCompiledTransform ConfirmedAddrTransform = HttpContext.Current.Cache["Transform"] as XslCompiledTransform 
    ConfirmedAddrTransform.Transform(_XMLReader, xslArgs, sXML);

}

Let me know if this work you.

Happy coding.... 

it works , thanks
