title: Pandas read file lines as a column
body: <p>I have a corpus of text files (multiple txt files), each with the structure like:</p>
  <pre><code>TITLE: some title
  URL: some url
  META: some meta
  DATE: some date
  AUTHOR(S): author
  TEXT: some text
  </code></pre>
  <p>How can I read the files, so that I have a dataframe with columns (title, url, ..., text)?
  Thank you!</p>
