scanning code/checkboxes question

can i scan the source code of a webpage? i will explain.
my site has the code

<tr bgcolor="#FFFFFF">
<td name="varname" height="21">&nbsp;</td>
<td height="21"><input type="checkbox" name="vart" onClick="CCA(this);"></td>
<td height="21">&nbsp;<a href="vlink.htm">vm</a>&nbsp;</td>
<td height="21">vd</td>
<td height="21">Jan 11</td>


this code is repeated for every occurence, the only difference in the repititions is that varname, vart, vlink and vd are different.
So can i scan through the code to see if any of these occur, so i could look to see if it said that varname was joebloggs and if it is it checks the checkbox in that block of code.

Is any of this possible?

I have a very limited knowledge of DOM Node structures and crap like that, however, I believe that this is a case where you'd need that. I'd probably as jkd, beetle, or brothercake as they are the first that come to mind, and are good at this sort of thing...
