Regex with positive lookahead across multiple lines

I've been trying to isolate blocks containing a certain string in TextWrangler.

Here is the sample I'm working with. 

<ROW num="381">
  <TO>8549672167</TO>
  <FROM>8936742582</FROM>
  <TIME>5/10/2009 19:49:3</TIME>
  <TEXT>Blah Blah Blah</TEXT>
</ROW>
<ROW num="382">
  <TO>8549672167</TO>
  <FROM>8591903412</FROM>
  <TIME>5/10/2009 19:49:37</TIME>
  <TEXT>Hme</TEXT>
</ROW>

What I'm trying to do is isolate all multi-line blocks beginning with <ROW and ending with </ROW>that contain the digits 412in the line beginning <FROM>

So in the above example, the second block would be highlighted, but not the first.

I have no idea where to begin with is, can anybody help? Thanks, MS.

Try this:

<ROW[^<]*?>[^<]*<TO>(?=[^<]*412)[^<]*<\/TO>.*?<\/ROW>
