I need some help with a regexp challenge.
Based on some custom inserted tags in the HTML code, I need custom attributes into the <td> tags between these custom tags.
example:
[DEL] is the custom tag and it's ended with [/DEL]
So
[DEL]<td>test</td><td>More
should become
<td diffMode="DEL">test</td><t
Here's a more complex example which may help in testing.
This table:
<table>
[DEL]
<tr>
<td>This is a cell</td>
<td>This is another cell</td>
<td>This is the third cell</td>
</tr>
[/DEL]
<tr>
[DEL]
<td>This is also a cell</td>
<td>Second cell on this row</td>[/DEL]
<td>Last cell</td>
</tr>
[DEL]
<tr>
<td>New cell</td>
<td>Cell</td>
<td>Cell</td>
</tr>
<tr>
<td colspan="2">New cell</td>
<td>Another cell</td>
</tr>
[/DEL]
<tr>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
</tr>
</table>
Should after the regexp become like this:
<table>
<tr>
<td diffMode="DEL">This is a cell</td>
<td diffMode="DEL">This is another cell</td>
<td diffMode="DEL">This is the third cell</td>
</tr>
<tr>
<td diffMode="DEL">This is also a cell</td>
<td diffMode="DEL">Second cell on this row</td>
<td>Last cell</td>
</tr>
<tr>
<td diffMode="DEL">New cell</td>
<td diffMode="DEL">Cell</td>
<td diffMode="DEL">Cell</td>
</tr>
<tr>
<td diffMode="DEL"> colspan="2">New cell</td>
<td diffMode="DEL">Another cell</td>
</tr>
<tr>
<td>Cell</td>
<td>Cell</td>
<td>Cell</td>
</tr>
</table>
i.e. all the [DEL] tags are removed and instead, all <td> tags involved are tagged with the special attribute diffMode="DEL".

Thank you Roonaan. That looks very promising.
Just one thing I forgot:
I need to keep the [DEL] tags
i.e.
[DEl]<td>Cell</td><td>Cell
should become
[DEL]<td diffMode="DEL">Cell</td><t
and not
<td diffMode="DEL">Cell</td><t
This is needed in case I have [DEL] tags inline inside the <td> tags (example: <td>This is some [DEL]text[/DEL] inside the cell</td>)
Just one more thing: It seems like I need to save the [DEL] tags as well.
It didn't keep more than the end tags, but I can manage it by inserting some custom tags which I perform an preg_replace on afterwards. If you have a better solution with the regexp, please let me know.
Here's an example how I'm doing it(Supporting both [DEL] and [INS]:
<?
$text = '<table>
[DEL]
<tr>
<td>This is a cell</td>
<td>This is another cell</td>
<td>This is the third cell</td>
</tr>
[/DEL]
<tr>
[DEL]
<td>This is also a cell</td>
<td>Second cell on this row</td>[/DEL]
<td>Last cell</td>
</tr>
[DEL]
<tr>
<td>New cell</td>
<td>Cell</td>
<td>Cell</td>
</tr>
<tr>
<td colspan="2">New cell</td>
<td>Another cell</td>
</tr>
[/DEL]
<tr>
<td>[INS]Cell[/INS][DEL]Co
<td>Cell</td>
<td>Cell</td>
</tr>
</table>';
$text = preg_replace("/\[(\/)?DEL\
$text = preg_replace("/\[(\/)?INS\
$startTag = '[DEL]';
$endTag = '[/DEL]';
$preg = '/'.preg_quote($startTag, '/').'(.*?)'.preg_quote($e
$text = preg_replace($preg, 'str_replace("<td", "<td diffMode=\"del\"", "\\1")', $text);
$startTag = '[INS]';
$endTag = '[/INS]';
$preg = '/'.preg_quote($startTag, '/').'(.*?)'.preg_quote($e
$text = preg_replace($preg, 'str_replace("<td", "<td diffMode=\"del\"", "\\1")', $text);
$text = preg_replace("/<(\/)?DEL>/
$text = preg_replace("/<(\/)?INS>/
echo nl2br(htmlspecialchars($te
