title: Vim Multi-line search pattern
body: <p>I have a substitute command that captures and displays submatch() values in the replacement string.  But I have another line of information that I want to parse below this line.  That line is always the first line after an empty line, though the number of lines TO that empty line varies.  For example:</p>
  
  <pre><code>The first important line I want to capture is here
  Stuff I don't want.
  A few more lines of stuff I don't want...
  
  Second line I want to capture.
  </code></pre>
  
  <p>This pattern repeats a hundred or so times in a document.  I can substitute "The First Important Line" fine, but shouldn't that search pattern include a way to jump down to the first empty line and then pick up the next "Second line I want to capture."  ??  I could then place the contents of that second line into submatch parenthesis and substitute them where needed (right?).  </p>
  
  <p>If so, I cannot discover the way to extend the first search pattern to capture the "Second line"  Suggestions or correcting my approach would be greatly appreciated.</p>
