Output schema

Question

BizTalk produces control characters at the beginning of the file when producing output xml. Is there any
change we can implement to the pipeline to remove the control characters at the beginning of the file.
I have opened the output xml file in notepadd++ with hex editor plugin view. the output file seems to have extra characters at the beginning of the file. Is there anyway we can remove it?

Hi Ragavali,
If you want to remove invalid character set from your request message you can use below code in Excute block
        public IBaseMessage Execute(IPipelineContext pc, IBaseMessage inmsg)
            string Reqxml,NewReqxml;
            Stream newStr;
            IBaseMessagePart bodyPart = inmsg.BodyPart;
            if (bodyPart != null)
                using (StreamReader sr = new StreamReader(bodyPart.GetOriginalDataStream()))
                    //Remove Invalid Character
                    Reqxml = sr.ReadToEnd();
                    string exp = @"[^\u0009\u000A\u000D\u0020-\uD7FF\uE000-\uFFFD\u10000-\u10FFFF]";
                    NewReqText= System.Text.RegularExpressions.Regex.Replace(Reqxml, exp, "");
                    byte[] b = new byte[newXMLText.Length * 2 + 2];
                    b[0] = 0xFF;
                    b[1] = 0xFE;
                    byte[] b = System.Text.UnicodeEncoding.Unicode.GetBytes(NewReqxml);
                    for (int i = 0; i < textb.Length; i++)
                        b[i + 2] = textb[i];
                    newStr = new MemoryStream(b);
                    newStr.Flush();
                    bodyPart.Data = newStr;
                    pc.ResourceTracker.AddResource(newStr);
           return inmsg;
Thanks
