Hi all,

I want to search within a string for patterns such as: <li> some text here… title=”word”
and retrieve a list of ‘word’s

Input: string with patterns such as the one shown above
Output: list of ‘word’ items

Comments welcome,
Ruben

@scragarJan 24.2008 — unless you give examples this is about as close as I can guess:

$string = '&lt;li&gt;stuff "copy" &lt;/li&gt;
&lt;li&gt;meap "another coppied word"&lt;/li&gt;';
preg_match("/&lt;li&gt;.+"([^"]+)".+&lt;/li&gt;/", $string, $matches);
var_dump($matches);// note every 0dd index is what your after.
code tags prevent forum messing up regexps. - tested and fixed.

Input

<li> stuff title="word1" </li>

<li> stuff title="word2" </li>

Output

array[0] = word1

array[1] = word2

Thanks,

Ruben

@scragarJan 24.2008 — [code=php]$x = '<li> stuff title="word1" </li>
<li> stuff title="word2" </li>';
preg_match_all("/[a-zA-Z]+="([^"]+)"/", $x, $matches);
print_r($matches[1]);[/code]how's that?

you could even use it in a function to make it easier to reuse:
[code=php]function find_val($input){
preg_match_all("/[a-zA-Z]+="([^"]+)"/", $input, $matches);
return ($matches[1]);
};

$x = '<li> stuff title="word1" </li>
<li> stuff title="word2" </li>';
$something = find_val($x);
print_r($something);[/code]

@rvazquezauthorJan 24.2008 — Ok, good solution; but, I didn't tell this...

Input

stuff title="I dont want this text because it is not between tags"

<li> stuff title="word1" </li>

<li> stuff title="word2" </li>

Output

array[0] = word1

array[1] = word2

[code=php]
<?php
$text="stuff title="I dont want this text because it is not between tags"n<li> stuff title="word0" </li>n<li> stuff title="word1" </li>";
preg_match_all("/<li>.+title="(.+)".*</li>/Uis",$text,$result);
print_r($result[1]);
?>
[/code]
it will output :

Array ( [0] => word0 [1] => word1 )
