Need help in string formatting function.

I have a string which contains object names enclosed in <>. Like this:

 

                                String str = 'I have <name> and <id>  and <phone>';  //The string may vary,so it needs to be dynamic

 

I need an output like this. So that i can use the field names to use it in my soql query.


                                String fields = 'name,id,phone';

try this.

 

String str = 'I have <name> and <id>  and <phone>';
List<String> lst = str.split(' ');
String fld = '';
for(String s:lst){
   if(s.contains('<') && s.contains('>')){
      s = s.replace('<','');
      s = s.replace('>','');
      if(fld == ''){
         fld = s;
      }else{
         fld += ',' + s;
      }
   }
}
system.debug('###### String: ' + str);
system.debug('###### fields: ' + fld);
