Java or XSLT mapping suits this requirement

ramu_g4 — Thu, 12 Apr 2018 14:47:05 GMT

Hi Experts,

We have requirement to transform the input & output payload as shown below screen shot where it should parse payload and " < " should be replaced with < & " #62 "should be replaced with " > " .

If you observe the whole xml payload contains ServiceOrder string with set of characters should be replaced with < infront & > after that string.

Please suggest Java or XSLT mapping suits this requirement.

Thanks.

Ramu.

I would try with XSLT first.

Hi Ramu!

I would read payload into string using java mapping and simply call replaceAll() method.

Hi Evgeniy,

Thank you for your response.

Can you help with Java mapping code to read the payload & use replaeAll() method to achieve this requirement so that I can export the java code as jar file & import it.

Thanks,

Ramu.

Hi Ramu!

public class StringReplacer extends AbstractTransformation {
@Override
public void transform(TransformationInput in, TransformationOutput out)throws StreamTransformationException {
executeMapping(in.getInputPayload().getInputStream(), out.getOutputPayload().getOutputStream());
}

public void executeMapping(InputStream is, OutputStream os) throws StreamTransformationException {
try {
byte[] payloadBytes = getByteArrayFromInputStream(is);
String payloadString = new String(payloadBytes, "UTF-8");
payloadString = payloadString.replaceAll("<", "<").replaceAll(">", ">");
os.write(payloadString.getBytes("UTF-8"));
}
catch (Exception e) {
throw new StreamTransformationException(e.getMessage());
}
}

public byte[] getByteArrayFromInputStream(InputStream is) throws IOException {
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int nRead;
byte[] data = new byte[16384];
while ((nRead = is.read(data, 0, data.length)) != -1)
  buffer.write(data, 0, nRead);
buffer.flush();
is.close();
return buffer.toByteArray();
}
}

Editor changes the representation of symbols, so, you should use your source values for "<" and ">" as the first argument in both replaceAll() methods.

Hi Evgeniy,

Regarding this line payloadString = payloadString.replaceAll("<", "<").replaceAll(">", ">");

should it corrected to achieve my requirement to replace < with "<" and to replace > with ">" .

payloadString = payloadString.replaceAll("<", "<") ;

payloadString = payloadString.replaceAll(">", ">") ;

Thanks,

Ramu.
