Assign HTML character entities

[Former Member]

Hello,

I have a scenario where a message should be sent to an HTTP server using the HTTP receiver CC. In the message itself no special HTML characters such as <, > or / should be used but they should be replaced with special character entities such as &lt for < .

Is there an easy way to do this as it is quite a common requirement? Is there an adapter module available for this or must this be done in the mapping itself?

Thank you for your advice.

Florian,

Can you check stefans comments in this thread:

I also checked the link to the other trhead. So obviously the conversion to HTML character entities, just like &lt has to be done using a Java mapping.

Is there any sample code available? I think this is a common feature and there should be some kind of java template available.

This would be very helpful.

public void execute(InputStream in, OutputStream out)
		throws StreamTransformationException {
try{    
int c;
    while ((c = in.read()) != -1) {
      switch (c){       
         case '&': out.write("&".getBytes()); break;    
         case '\"': out.write(""".getBytes()); break;
         case '\'': out.write("'".getBytes()); break;
         case '<': out.write("&lt;".getBytes()); break;
         case '>': out.write("&gt;".getBytes()); break;
         default: out.write(c);
       }

    }
  } catch (IOException e) {
    throw new StreamTransformationException(e.getMessage());
  }


}

If that works for you, you can put this to wiki

Thank you very much for the sample. I will try the code and let you know afterwards (will take some days / weeks though as I have to finish all other requirements first)

The SDN forum does not allow html escape sequences, so I put a space before the ; which you have to remove in your code.

' and " need not to be escaped, so I removed that lines.

Thank you for the code sample! What I was just thinking about is, that this should be done automatically when receiving the proxy, shouldn't it?

Otherwise it would not be valid XML on the integration server I guess.

And how would the code distinguish between "real" XML tags and content of elements? We will make a test and I let you know about the outcome.
