Hi I'm writing a program that allows users to check in, check out, or delete books from a library. all the data is in a html table. I was wondering if there was an easy way of reading data from a table. Or do I have to parse it looking for the <td> and <tr> tags which is teadious. Thanks for any suggestions ahead of time.

What do you mean your data is in an html table? Do you mean that it has been loaded into an html table? From where? Normally you display an html form asking for user input, then use POST or GET action to submit the form to another script(many times the same script that just displayed the blank form), and then that script &quot;read&quot;s the data from the form. Is that what you mean?

It's not <that> tedious..... is it ;-).... maybe this is barking up the right tree....

-----------------------------------------------------------------
$html = '<HTML>
<HEAD></HEAD>
<BODY>
<TABLE.... you get the idea.../table>
</body>
</html>';

$html =~ /<table.*?>(.*?)</table>/gis;
$table = $1;
while ($table =~ /<tr>(.*?)<\/tr>/gis)
{
$row_num++;
$table_row = $1;
undef @tmp_array;
while ($table_row =~ /<td>(.*?)<\/td>/gis)
{
# got a table definition
push $tmp_array,$1;
}
$table_info_hash{$row_num} = \@tmp_arry;
}
-----------------------------------------------------------------

I have not run that, but hopefully it illustrates using a few regex's to get the contents of an HTML table into a memory structure.

Do I have the refercence to @tmp_array right? <ponder.... I don't have time to check it at the moment..... ponder>

HTH - gotta' go to work.

ok thanks goBoating that helps a lot. And yes the form and data is placed in an html table. Like each row of the table has a checkbox for edit or delete and then the name of the book type thing. I just wanted to know how to parse the table to get the values easily. Thanks.
