Hi Venky,
Use below UDF
public String split(String input, Container container) throws StreamTransformationException { StringBuilder sb = new StringBuilder(); input = " " + input; String patternStr = "\\s[A-Z0-9]{2}\\-"; Pattern pattern = Pattern.compile(patternStr); Matcher matcher = pattern.matcher(input); List<Integer> indexes = new ArrayList<Integer>(); while (matcher.find()) { indexes.add(matcher.start()); } for (int i = 0; i < indexes.size(); i++) { int endIndex = indexes.size() > i + 1 ? indexes.get(i + 1) : input.length(); String token = input.substring(indexes.get(i), endIndex); token = token.substring(1); if (token.startsWith("E2-") || token.startsWith("GI-")) sb.append(token.substring(3).replace("-", "|")).append("|"); } sb.setLength(sb.length() - 1); return sb.toString(); }Regards,
Praveen.
