below code using pattern matching

pattern pattern = pattern.compile("<b>.*?</b>", pattern.dotall |  pattern.unicode_case | pattern.multiline); matcher matcher = pattern.matcher(input); stringbuilder builder = new stringbuilder(); int lastindex = 0; while (matcher.find()) {     builder.append(input.substring(lastindex, matcher.start()));     lastindex = matcher.end(); } builder.append(input.substring(lastindex)); 

below scenerio failing above pattern

 <a><b><![cdata[test 123 </b><c>inside</c>]]></b><c>outside</c><d></d><e>out side</e></a>
