This is just a follow-up to note that my description of the regex above is
incorrect. I meant to say it will match from the innermost table containing
"Code 2".
Note that it also supports, e.g., nested tables not containing "Code 2"
appearing before "Code 2" in a table which contains it. E.g., with...
<table>
<tr>
<td>
<table><tr><td>Code 1</td></tr></table>
</td>
<td>Code 2</td>
</tr>
</table>
It would match from the first <table> tag until the "2". Hence, it would
correctly match from the beginning of the innermost table containing "Code
2" (the nested table doesn't contain it).
