title: Combine multiple Regex.Replace calls
body: <p>I've got a text processor, which includes hundreds of Regex.Replace calls. Many of them work on the same text. They would for example remove white spaces and unwanted characters, put brackets around numbers, remove black-listed words, etc. </p>
  
  <p>Is there a way to make multiple replacements with different patterns with a single call? I'm wondering about that, because my code currently is quite slow and I guess that would save some cycles.</p>
