[jQuery] Finding selectors between two points

[Pops]

I have a table with some <tr> is used as divide other rows:

  <tr class="versionSection">....
  <tr>...
  <tr>..
  <tr>..
  <tr class="versionSection">....
  <tr>..
  <tr>..
  ...
  <tr class="versionSection">....
  <tr>..
  <tr>..

etc.

In lieu of changng the HTML page, I want to see if I can find the <tr>
after each class="versionSection" row.   I want to do a toggler for
each section.

  //----------------------------------------------------------
  // - Click title row to toggle the remaing section rows.
  //----------------------------------------------------------
  var $f = $(".versionSection");
  $f.click(function() {
      var $r = $(this).next("tr > !.versionSection");
      $r.toggle();
   });
  //----------------------------------------------------------

Its close, but obviously not right. It only gets the first next row.
I need it to return all the rows until the next .versionSection class
row..

Any tips in a selector?

TIA
