OK, u are trying to make a spider.
U don't really need to use reg. exp. u can use string functions too ...
If I were u I could something like that:
1. Create an array where elements are the rows table ("<tr>...</tr>");
2. Parse the array and create a bi dimensional array where the second dimension elements represent columns ("<td>..</td>"), of course u can strip the string by html tags ...
For now u should have something like this:
$tmp[0][1] = "5095WA";
$tmp[0][2] = "SUBJECT1";
......
$tmp[0][3] = "0.350";
And with this array u can do what ever u want...
Reg. exp. are not easy to use, I don't really like them because I don't know them very well, so when I had stuff like this to do I use string functions ....
