title: Regular Expression Match variable multiple lines?
body: <p>Lets say I have the following text and I want to extract the text between "Start of numbers" and "End of numbers" there are dynamic amount of lines and the only thing which changes in the numbers in them eg: first, second, etc. Each file I'll be extracting data from has different amount of lines between between "Start of numbers" and "End of numbers". How can I write a regex to match the content between "Start of numbers" and "End of numbers" without knowing how many lines will be in the file between Start of numbers" and "End of numbers"?</p>
  
  <p>Regards!</p>

  This is the first line
  This is the second line
  This is the third line
  This is the ...... line
  This is the ninth line
  
  End of numbers
