Structural replace -- fields rename by pattern

I want to rename all fields in mine VO classes -- they have 'm_' prefix which I'd like to remove.

Now:
private ReportTemplate m_reportTemplate;
Should be:
private ReportTemplate reportTemplate;

I've tried to do it via Structural Replace, but no any success. My last pattern looks like

class $_1$ { 
  void $MethodName$ ($ParameterType$ $Parameter$){
       $Var$ = $Parameter$
       }
