That appears to be a PDF conversion remnant
REGEX is your buddy. There are tutorials here on MR.
<p class="something">(88 of 243)20-2-2006 21:47:27</p>
(I added the rest of the paragraph in purple , to avoid possibility's of over cleaning)
Code:
<p class="\w+">\(\d+ of \d+\)\d\d-\d{1,2}-\d{4}\s\d\d\:\d\d:\d\d</p>
You may need to adjust the former purple part based upon what you see. Other adjustments based upon what you see. There is no single REGEX to rule them all. I keep basic patterns (as a template) like above, and adjust (and test), in saved searches.
\d is a digit, + allows multiplies. {#} is an exact quantity of them
\s is whitespace
I 'escaped' symbols to be safe \( \) as they can have meaning in a pattern
