me again

I'm very new to progamming

your script looks very interresting

I'm playing with example5_google_results.php

but I would like to return for example only the links of the websites that google indexes... not the cached, not the related, nothing else than a list of link

something like
link 1 = http://www.link1.com
link 2 = http://www.link2.com

but I really don't undertstand how do to it

thanx you in advance for your help

Steffy

it's very simple ... instead of using "title","content","cache","similar", you should replace that with "dummy" in $obj->pattern. then, all the results are having this two variables, "dummy" and "link". you'll use the "link" variable as you need.
enjoy.

thank you for your time and tips, but I'm blonde !!

here is how I configure your class

=============================================================================
$obj=new MySpider();
$obj->url="http://www.google.com/search?q=kitesurf&start={range[0]}";
$obj->range=array(0=>array("start"=>0,"end"=>1,"step"=>1));
//$obj->pattern_definition=array("dummy","link","title","content","cache","similar"); //dummy is used for content that changes between pages and we are not interested in it
$obj->pattern_definition=array("dummy","link"); //dummy is used for content that changes between pages and we are not interested in it

$obj->start='<div>';
$obj->end=array("to_process"=>array('</body>'),"not_to_process"=>array());
//$obj->pattern='<div class=g{p[dummy]}><h2 class=r><a{p[dummy]}href="{p[link]}"{p[dummy]}class=l{p[dummy]}>{p[title]}</a></h2><table border=0 cellpadding=0 cellspacing=0><tr><td class=j><font size=-1>{p[content]}<br><span{p[dummy]}>{p[dummy]}</span><nobr><a class=fl href="{p[cache]}">{p[dummy]}</a> - <a class=fl href="{p[similar]}">{p[dummy]}</a></nobr></font></td></tr></table></div>';
$obj->pattern='<h2 class=r><a{p[dummy]}href="{p[link]}"{p[dummy]}class=l{p[dummy]}><br />';

$obj->fetchData();
================================================================

====================================================================

but what I want to achieve would be simply
[1] => http://.....
[2] => http://.....
[3] => http://.....
[4] => http://.....
[5] => http://.....

and so on

is that possible and if so how shall I process?

thanx you in advance

Steffy

use this pattern instead:
$obj->pattern='<div class=g{p[dummy]}><h2 class=r><a{p[dummy]}href="{p[link]}"{p[dummy]}class=l{p[dummy]}>{p[dummy]}</a></h2><table border=0 cellpadding=0 cellspacing=0><tr><td class=j><font size=-1>{p[dummy]}<br><span{p[dummy]}>{p[dummy]}</span><nobr><a class=fl href="{p[dummy]}">{p[dummy]}</a> - <a class=fl href="{p[dummy]}">{p[dummy]}</a></nobr></font></td></tr></table></div>';

you can then delete all the dummies with unset().
good luck.

in my google example you have already a good unset example :
function processData($pattern_matches) //you can do whatever you want here with the pattern matches, insert in a database etc.
{
foreach ($pattern_matches as $k=>$v)
{
if($v['dummy'])
{
unset($pattern_matches[$k]['dummy']);
}
}
print_r($pattern_matches);
}

you shouldn't modify the pattern !!
you can add <a href="" to each link after processing, in processData function.
have a nice day.
