How do i do a Advance replace string logic?

Question

Hi all,
I have an issue on writing a logic to replace a string in a sentence
Suppose i fill in 3 input
1st input - *"The Name contains 'Test1' and 'Test2' and this is it"*
2nd input - *"The Name contains \"{mercName1}\" and \"{mercName2}\" and this is it"*
3rd input - *"(\"{mercName1}\")) and (\"{mercName2}\"))"*
The logic will compare 1st input and 2nd input, then replace mercName1/mercName2, and the output should be like this
output - *("'Test1'")) and ("'Test2'"))*
Currently i have make it works and here's the logic
public class ReplaceString {
     private String getRuleMap(String strRuleC_DRL, String strRuleM_Desc, String strRuleM_Map) {
          String[] strRuleC_DRL_split = strRuleC_DRL.split(" ");
          String[] strRuleM_Desc_split = strRuleM_Desc.split(" ");
          Map compareMap = new HashMap();
          if(strRuleC_DRL_split.length == strRuleM_Desc_split.length) {
               for(int x=0; x<strRuleC_DRL_split.length; x++) {
                    int compare = strRuleC_DRL_split[x].compareTo(strRuleM_Desc_split[x]);
                    if(compare != 0) {
                         compareMap.put(strRuleM_Desc_split[x].replaceAll("\"", ""), strRuleC_DRL_split[x].replaceAll("\"", ""));
          if(!compareMap.isEmpty()) {
               Iterator keyIter = compareMap.keySet().iterator();
               while(keyIter.hasNext()) {
                    String theKey = keyIter.next().toString();
                    String theValue = compareMap.get(theKey).toString();
                    if(strRuleM_Map.indexOf(theKey) > 0) {
                         strRuleM_Map = this.replace(strRuleM_Map, theKey, theValue);
          return strRuleM_Map;
     private String replace(String source, String pattern, String replace) {
          if (source!=null) {
               final int len = pattern.length();
               StringBuffer sb = new StringBuffer();
               int found = -1;
               int start = 0;
               while( (found = source.indexOf(pattern, start) ) != -1) {
                    sb.append(source.substring(start, found));
                    sb.append(replace);
                    start = found + len;
               sb.append(source.substring(start));
               return sb.toString();
          else return "";
      * @param args
     public static void main(String[] args) {
          // TODO Auto-generated method stub
          ReplaceString rs = new ReplaceString();
          System.out.println(rs.getRuleMap("The Name contains 'Test1' and 'Test2' and this is it", "The Name contains \"{mercName1}\" and \"{mercName2}\" and this is it", "(\"{mercName1}\")) and (\"{mercName2}\"))"));
}Now, here's the problem, when i key in
input - *"The Name contains 'Test1 and Test2' and 'Test3 and Test 4' and this is it"*
i expect the output should be
output - *("'Test1 and Test2'")) and ("'Test3 and Test4'"))*
but i hit problem cause the string compare is only 1 to 1
Is there any advice? Thanks

You could try to use regular expressions?
