searching a html page for a font using PHP 1

chineerat · May 17, 2007

hello there
i would like to search a query generated page for a particular font colour/type for example:
the link:

http://www.google.tt/search?hl=en&q=green&btnG=Google+Search

what is the PHP function for extracting font of the colour green? or fonts: blue and underline.

The difficulty is that google uses classes. I just used google as an example. The site i am expected to use may not have classes embeded. I am expecting the site to use simple basic HTML.
for example:
"<html><body><font color="green">.........<font color="green"> </body> </html>
am i to use a String search?

can anyone help, THANKS alot in advance.

use preg_match_all()

the regex and function call would look something like this (this is an imperfect regex but it should give you a start).

Code:

$html = "<html><body><font color="green">first text to be captured</font>some other text that will not be captured<font color="green">text to be captured</body> </html>"
$pattern = '/<font color="green">(.*?)</font>/i';
preg_match_all($pattern, $html, $matches);

echo "<pre>".print_r($matches, true);

i am getting the error
Parse error: parse error, unexpected T_VARIABLE in c:\inetpub\

on line 1

does it have to do with the fact that
$html uses double quotes and <font colour "green"> has double quotes?
will this cause a conflict?

probably more to do with a lack of semicolon at the end of line 1.

but also, the enquoting was wrong, as you point out.

try this

Code:

$html = <<<HTML
<html><body><font color="green">first text to be captured</font>some other text that will not be captured<font color="green">text to be captured</body> </html>
HTML;

or put the html in a separate file and

Code:

$html = file_get_contents ("separatefile.txt");

i didn't get method one to work, but method 2 works.
thanks

the heredoc syntax is very sensitive to spaces on the first and last lines

Code:

echo <<<HTML[red]NO MORE SPACES HERE[/RED]
...
...
...
HTML;[red]the ending delimeter (HTML) must be hard against the left edge and there must be no characters after the delimiter apart from the semicolon[/red]

glad you got it sorted though.
