title: Aggregate multiple jquery selectors with common parent
body: <p>I have several selectors with a common parent.
  Is there a good method to put them under a single function call?
  For example:</p>
  
  <pre><code>$('td.postbody').children('a[href$=".gif"], a[href$=".jpg"], a[href$=".png"], a[href$=".bmp"]').addClass("zoom2 itag").attr('title','Click to Expand Image.');
  $('td.postbody').children('a[href$=".GIF"], a[href$=".JPG"], a[href$=".PNG"], a[href$=".BMP"]').addClass("zoom2 itag").attr('title','Click to Expand Image.');
  $('td.postbody').children('a:not([class])').addClass("smlLink");
  $('td.postbody').children('img:not([src^="modules/"])').attr("height", "200").addClass("image-link");
  </code></pre>
  
  <p>I'd like to put them under a common function like:</p>
  
  <pre><code>$('td.postbody').children('a','img')).each(function(){...});
  </code></pre>
  
  <p>I looked at some of the uses of variables but what I found, didn't look like it would work for this.<br>
  My logic is select all the $('td.postbody').children('*') at one time then process the group, rather than scanning the document several times.
  Is this good logic for jQuery? Should my approach be different?
  Thx,
  Chris</p>
