Radovan,
Searching for words that are not the same color as the background could be
interesting depending on a lot of things.
1. Does the page use CSS?
2. Are background/font colors defined as "red" or "#FF0000"?
3. Where are background colors defined? (i.e. <body> or <table> or <td> or
...) (you already answered this one...oops)
4. Are you loading this into a database or is it a script to search just a
single page?
This sounds rather complicated, but nothing a clever hack couldn't fix :)
You'll likely want to read the file line by line, storing the most current
background color in a variable, then comparing to see if any text is NOT
that color, then loading those words to an array (likely). Then, if a
background color changes, you'll update the variable (at that point).
Perhaps, if background colors are always defined as bgcolor, you should
split the string up by that so if a bgcolor setting is midway through the
line it won't miss text before that bgcolor setting. i.e.:
<hr><font color=#555555>blah grey text<table bgcolor=#555555>
<tr><td>moretext</td></tr></table>
etc.
Just thoughts off the top of my head. No guarantees.
