Newbie question.

I understand that one can open a page off an existing website to extract
text data using a PHP script by using the fopen and fread functions.

And by using the strip_tags() function, one can extract data without the
html markup as a literal string.

Here's my question...

Let's say that a html page from a website out on the 'net consists of three
paragraphs of text and four html tables.

Within each of those tables is text.

And let's say that the second table down has three columns - water
temperature, water level and cfs flow along with numerous records.

Is there any way to extract *specific* data off a page - in this case - the
second table - while leaving the balance of the text and the other tables
 1, 3 and 4) alone?

Thank you.
