Pipeline component for replace the values in send pipeline 837P

Question

hi friends,
I am working in 837P splitting the claims.When i am sending using sendpipe line.
I need  pass the 2010bb loop NM103 and NM109 defaluts values,
ex: NM103=100,NM109=0123456789
like can you help me write pipeline component to manipulate the XPath and replace the default values.
THanks

Answer 1

you will need to extract data from the message coming on your receive location.
You can create two diffferent function which can do your task.
The first one is to get the stream from the message and create a seekable one to be used later on.
private Stream GetMessageStream(Microsoft.BizTalk.Message.Interop.IBaseMessage msg, Microsoft.BizTalk.Component.Interop.IPipelineContext context)
   Stream stream = msg.BodyPart.GetOriginalDataStream();
    if (!stream.CanSeek)
        ReadOnlySeekableStream readStream = new ReadOnlySeekableStream(stream);
        if (context != null)
            context.ResourceTracker.AddResource(readStream);
        msg.BodyPart.Data = readStream;
        stream = readStream;
    return stream;
The second method is the one that would perform the data extraction as follows.
private string ExtractDataValueXPath(Stream MsgStream, string MsgXPath)
    XmlReaderSettings settings = new XmlReaderSettings()
      ConformanceLevel = ConformanceLevel.Document,
        IgnoreWhitespace = true,
        ValidationType = ValidationType.None,
        IgnoreProcessingInstructions = true,
        IgnoreComments = true,
        CloseInput = false
    MsgStream.Seek(0, SeekOrigin.Begin);
    XmlReader reader = XmlReader.Create(MsgStream, settings);
    string strValue = null;
    if (!string.IsNullOrEmpty(MsgXPath))
        if (reader.Read())
            XPathDocument xPathDoc = new XPathDocument(reader);
            XPathNavigator xNavigator = xPathDoc.CreateNavigator();
            XPathNodeIterator xNodes = xNavigator.Select(MsgXPath);
            if (xNodes.Count != 0 && xNodes.MoveNext())
                strValue = xNodes.Current.Value;
            MsgStream.Seek(0, SeekOrigin.Begin);
    return strValue;
You can update the node with the Xpath of the element.
