FCC For csv WITHOUT new lines

Question

Hello to everybody,
I trying to do a file content conversion for the following file :
a;b;c;d;a;b;c;d;a;b;c;d
Problem :
file has 4 fields meaning that there is not a nl after each line . The correct file for instance have to be
a;b;c;d
a;b;c;d
a;b;c;d
Target structure :
line
field a
field b
field c
field d
line
field a
field b
field c
field d
etc...
is this achievable ?
just to be more clear :
The incoming csv file has all it's lines continuoysly : no new line after each record ..

Hi Laurent Fournier,
As you said, if your given a flat file containing "a;b;c;d;a;b;c;d;a;b;c;d" you will replace every 4th ";" with "new line". Then you want it to be converted into XML.
Now let's try to achieve the same using SAP PI. As Sender File FCC can not handle this situation, it should be handled in Adapter module or Mapping.
Let's do it in simple Java Mapping (as Graphical and XSLT can not handle non XML input).
package com.mapping;
import java.io.*;
import com.sap.aii.mapping.api.*;
public class SimpleJavaMapping_PI71 extends AbstractTransformation
     public void transform(TransformationInput transformationInput, TransformationOutput transformationOutput) throws StreamTransformationException
          try
               InputStream inputstream = transformationInput.getInputPayload().getInputStream();
               OutputStream outputstream = transformationOutput.getOutputPayload().getOutputStream();
               byte[] b = new byte[inputstream.available()];
               inputstream.read(b);
               String strContent = new String(b);
               float fStrContent = strContent.length();
               int iCountColon = 0;
               StringBuilder strOutputContent = new StringBuilder();
               for (int i = 0; i < fStrContent; i++)
                    char cTemp = strContent.charAt(i);
                    if (!";".equals(cTemp))
                         strOutputContent.append(cTemp);
                    } else
                         if (4 != iCountColon)
                              strOutputContent.append(cTemp);
                              iCountColon++;
                         } else
                              strOutputContent.append(System.getProperty("line.separator"));
                              iCountColon = 0;
               outputstream.write(strOutputContent.toString().getBytes());
          } catch (Exception exception)
               exception.printStackTrace();
You can also implement this logic in adapter module in sender channel and then use FCC to convert it into XML. Or you can implement above Java Mapping, followed by another Java Mapping to convert output of above code into XML using DOM parser.
