IE Automation - search source code for string

Hello,

I am trying to do a test whether a string on a webpage.  The problem is the text is encoded into a javascript function, so I cant do GetElementsBy....  Below is the source code I am looking at (I just attached the script the string is in), and a snipet of the line containg the string i need ("Parts not found !!".  Thank you.

str = str + "  <td class=\"LT_dataR\"><font color=red>Parts not found !!</font><a href='javascript:beforeOpenAlter(0);' onbeforeactivate='JAVASCRIPT:ignoreChange(true);'><img src='/gspn/images/en/Icon_search.gif' border=0 hspace=2 align='absmiddle'></a></td>";
      str = str + "</tr>";
