Hi all, I need a little help about creating regex wit this piece of code. I need cut all the code except bolded text (without br tag) which should be output of PHP script. So, I need a text inside pre tag, but without br tag. Does anybody knows how to do that? <html> <head> <title>Title</title> <link href="/css/some.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="some.js"></script> </head> <body> <div class="some text"> <div class="title"> Some Title </div> <h3>Subtitle</h3> <p>Some text, another text, etc..</p> <p>Some another text.</p> I need only these numbers (in php array, if it is possible)---><pre>86,45,20,26,37,18,2,82,33,25,59,90,73,26,28,85,87,75,20,79,14,72,59,63,32,<br />72,62,12,46,29,39,36,61,45,7,72,54,14,86,47,33,90,23,72,78,43,98,77,99,32,<br />95,95,91,0,72,47,65,79,51,31,46,20,93,0,79,91,20,59,47,52,51,47,63,60,0,<br />68,28,22,67,62,63,43,10,77,13,29,31,27,8,52,84,57,81,85,78,27,80,16,51,52,<br />44,73,69,42,61,54,57,39,41,69,53,34,28,17,30,21,30,58,67,3,65,36,95,25,6,<br />34,83,19,80,47,32,22,95,13,81,43,30,34,95,3,39,68,89,53,83,6,76,51,44,76,<br />73,74,79,26,37,2,44,12,94,99,19,65,98,28,95,93,43,17,20,95,6,63,57,59,6,<br />90,14,88,28,19,70,1,12,48,73,84,74,37,42,36,32,93,42,67,13,7,19,19,72,79,<br />39,33,17,56,24,34,56,45,8,91,89,27,30,22,17,74,52,8,71,41,9,86,11,78,31,<br />48,79,68,56,31,27,76,54,92,91,58,36,89,31,12,16,5,79,77,55,75,2,48,72,3,<br />42,36,13,28,24,34,37,42,31,77,79,43,88,42,1,83,88,40,8,83,64,65,54,94,18,<br />82,35,54,61,92,84,5,46,56,64,71,49,69,65,36,86,30,57,60,41,99,97,35,66,96,<br />71,52,4,65,7,70,3,52,38,95,5,52,86,48,17,66,28,83,58,66,21,46,24,50,42,<br />72,34,67,83,41,33,9,4,12,34,77,19,26,8,65,29,42,11,44,82,8,51,30,12,18,<br />83,1,79,0,64,26,1,32,24,16,72,25,17,21,47,81,69,99,34,98,79,39,74,65,11,<br />26,59,42,77,63,45,49,15,39,5,77,64,86,54,30,26,48,93,28,38,66,96,29,10,87,<br />82,22,49,88,4,19,86,11,96,45,66,89,60,41,73,42,71,34,33,63,81,2,3,68,2,<br />23,93,59,80,50,47,52,3,56,33,74,98,54,45,99,14,89,47,40,35,17,36,12,32,60,<br />24,51,49,17,7,18,15,40,40,59,89,23,34,0,12,57,86,76,9,87,68,11,72,79,76,<br />6,87,38,3,36,71,34,82,84,90,14,27,30,29,83,16,71,51,31,49,59,95,32,84,84<br /></pre> <div id="show"><<a href="#" onMouseOver="toggleDiv('explain',1)" onMouseOut="toggleDiv('explain',0)">explain</a>></div> <div id="explain"><p>Explaination</p> <p>blablabla</p> <p>bla bla</p></div> </div> </body> </html> |

If there is only one place where it says <pre>text</pre> then you could try and use this:
<?
$html = "<html>
<head>
<title>Title</title>
<link href='/css/some.css' rel='stylesheet' type='text/css' />
<script type='text/javascript' src='some.js'></script>
</head>
<body>
<div class='some text'>
<div class='title'> Some Title </div>
<h3>Subtitle</h3>
<p>Some text, another text, etc..</p>
<p>Some another text.</p>
I need only these numbers (in php array, if it is possible)---><pre>86,45,20,26,37,18,2,82,33,25,59,90,73,26,28,85,87,75,20,79,14,72,59,63,32,<br />72,62,12,46,29,39,36,61,45,7,72,54,14,86,47,33,90,23,72,78,43,98,77,99,32,<br />95,95,91,0,72,47,65,79,51,31,46,20,93,0,79,91,20,59,47,52,51,47,63,60,0,<br />68,28,22,67,62,63,43,10,77,13,29,31,27,8,52,84,57,81,85,78,27,80,16,51,52,<br />44,73,69,42,61,54,57,39,41,69,53,34,28,17,30,21,30,58,67,3,65,36,95,25,6,<br />34,83,19,80,47,32,22,95,13,81,43,30,34,95,3,39,68,89,53,83,6,76,51,44,76,<br />73,74,79,26,37,2,44,12,94,99,19,65,98,28,95,93,43,17,20,95,6,63,57,59,6,<br />90,14,88,28,19,70,1,12,48,73,84,74,37,42,36,32,93,42,67,13,7,19,19,72,79,<br />39,33,17,56,24,34,56,45,8,91,89,27,30,22,17,74,52,8,71,41,9,86,11,78,31,<br />48,79,68,56,31,27,76,54,92,91,58,36,89,31,12,16,5,79,77,55,75,2,48,72,3,<br />42,36,13,28,24,34,37,42,31,77,79,43,88,42,1,83,88,40,8,83,64,65,54,94,18,<br />82,35,54,61,92,84,5,46,56,64,71,49,69,65,36,86,30,57,60,41,99,97,35,66,96,<br />71,52,4,65,7,70,3,52,38,95,5,52,86,48,17,66,28,83,58,66,21,46,24,50,42,<br />72,34,67,83,41,33,9,4,12,34,77,19,26,8,65,29,42,11,44,82,8,51,30,12,18,<br />83,1,79,0,64,26,1,32,24,16,72,25,17,21,47,81,69,99,34,98,79,39,74,65,11,<br />26,59,42,77,63,45,49,15,39,5,77,64,86,54,30,26,48,93,28,38,66,96,29,10,87,<br />82,22,49,88,4,19,86,11,96,45,66,89,60,41,73,42,71,34,33,63,81,2,3,68,2,<br />23,93,59,80,50,47,52,3,56,33,74,98,54,45,99,14,89,47,40,35,17,36,12,32,60,<br />24,51,49,17,7,18,15,40,40,59,89,23,34,0,12,57,86,76,9,87,68,11,72,79,76,<br />6,87,38,3,36,71,34,82,84,90,14,27,30,29,83,16,71,51,31,49,59,95,32,84,84<br /></pre>

<div id='explain'><p>Explaination</p>
<p>blablabla</p>
<p>bla bla</p></div>
</div>
</body>
</html>";
$text = split('<pre>', $html);
// $text[1] should have <pre> -> EOF
$numbers = split('</pre>', $text[1]);
// $numbers[0] should be now the numbers you want //
$numbers = str_replace("<br />", "", $numbers);
// final var is $numbers[0] //
echo $numbers[0];
?>
My PHP is a little rusty so i may have somethings a little mixed up or wrong way round, but it should be near enough correct  .Edit: Just tested it and it seems to be working fine, the only problem i had was it kept giving me an error because when i defining the $html var there was mixed " and ' in the html code. The script i posted above does work and displays the numbers as 1 string. |

i'm no php-wiz but (there is always a but) I believe it's something like this
ereg("<pre>(.*)</pre>",$input,$hits);
echo $hits[1];
but i strongly recommend you - test that - are aware that under some circumstances evaluating regular expressions, can lead to code execution  |

I suggest you this pseudo-code: 1. Take the text between the <pre> tags. 2. Replace the <br> tags with empty strings. (you could also eleminate _all_ html tags with a regex) 3. Replace the commas(,) with a space. 4. Loop over the text, scan one number at a time and store it in the array, loop until you reach the end of text. Step 4 can be done in many ways (especially in PHP), Here is an example that _might_ work. Didn't try it out and i didn't code php for some time. Also this is a bad solution, because it is very slow.  Quote from Scratch:$nums = array(); while ($text != "") { // as long as there is text left: $nums[] = (int) substr($text, 0, strpos($text, " "); // scan a number and append it to array. $text = substr($text, strpos($text, " "); // new text is the the text after first space. } |

this may help you
preg_match_all("/(\d+)\D+/",$input,$output);
var_dump($output);

Thanks again guys! @quangntenemy: "...302 challs solved, too 1337 to be ranked ..." Maybe it is an only reason...? btw, it is not spoiling, it is only pure regex question. Don't afraid, you're untouchable there... |
