title: Regex find and replace pattern matches with other pattern
body: <p>It is common way to replace a pattern match with string, but I need to replace all sub-strings which match pattern from text to be matched as another pattern match, is it possible?</p>
  
  <p>For example, is it possible to replace all matches to
  <code>[0-9]{2}'[0-9]{2}</code> which represent all strings like <code>99'99</code> or <code>85'55</code></p>
  
  <p>To this <code>[0-9]{2}.[0-9]{2}</code>  which represent all strings like <code>99.99</code> or <code>85.55</code></p>
  
  <p>Is it possible? How to do this kind of replacements?
  or I have to handle it manually through matches in for each loop?</p>
