title: Extracting people names from emails
body: <p>I have a big table with only one row containing email addresses and I need to get people's names from emails where it is possible. For example, from the mail daniela.meyer@example.de I need to get a name (daniela) and a surname (meyer).
  I think I need table with people names and compare each email with this database. But I can't understand what is the correct way of doing such a comparison ?</p>
