preg_replace to Remove Only Certain Rows from HTML Table

An html table stored in a variable as a lot of rows like this, and I want to remove only some of them, depending on what is in the spot that says "Some Words Here":

<FONT FACE="Arial,Helvetica,sans-serif" SIZE="2"  COLOR="#000000">Some Words Here</FONT></TD><TD>
<FONT FACE="Arial,Helvetica,sans-serif" SIZE="2"  COLOR="#000000">Blah Blah </FONT></TD><TD NOWRAP align=center>
<FONT FACE="Arial,Helvetica,sans-serif" SIZE="2"  COLOR="#CCFFCC">1/1/2005<BR>1:00:01 AM</FONT></TD><TD ALIGN="right" NOWRAP>
<FONT FACE="Arial,Helvetica,sans-serif" SIZE="2"  COLOR="#000000">1,234</FONT></TD><td width=48 valign=middle><FONT FACE="Arial,Helvetica,sans-serif" SIZE="2"  COLOR="#CC0000"><b>&nbsp;&nbsp;<NOBR>0.00</NOBR></b></FONT></td><TD ALIGN="right" NOWRAP> <b>
<FONT FACE="Arial,Helvetica,sans-serif" SIZE="2"  COLOR="#000000"><FONT FACE="Arial,Helvetica,sans-serif" SIZE="2"  COLOR="#CC0000">0.00%</b></TD>

Let's say one of the rows has "This is nice" instead of "Some words here."  I tried this regex, but it was ignored:

$table = preg_replace('/<TR VALIGN=\"middle\" BGCOLOR=\"#CCEEFF\"><TD NOWRAP>
<FONT FACE=\"Arial\,Helvetica\,sans-serif\" SIZE=\"2\"  COLOR=\"#000000\">This is nice(.*?)
<\/TR>/is', '', $table);

How can I make this work to delete the row that has "This is nice"?

Also, if I have several specific rows to delete (identified by different key words), would it make sense to explode all the rows into an array and then delete the array elements that contain the given keywords? If so, how?
