preg_hell

Anon

I am trying to get blocks of text between 2 <hr> tags in a row, into an array item.

like this:
<hr><hr>text to grab 1<hr><hr>
<hr><hr>text to grab 2<hr><hr>
<hr><hr>text to grab 3<hr><hr>

I want to take each block of text and get it in an array. heres where I am...

$html = file("test.html");
$html[] into one variable named $string
$string = implode("", $html);
preg_match_all ("/<HR><HR>.*<HR><HR>/i", "$string", $matches);
$array=explode("<hr><hr>",$matches);
echo $array[4];

For some reason I am having issues. Any help is much appreciated.

Try this:

<?php

$string='
<hr><hr>text to grab 1<hr><hr>
<hr><hr>text to grab 2<hr><hr>
<hr><hr>text to grab 3<hr><hr>
';

preg_match_all ("/<hr><hr>(.*)<hr><hr>/i", "$string", $matches);
var_dump($matches[1]);

Thanx! That gives me something I can work with.

maybe you should also try "/<hr><hr>(.*?)<hr><hr>/i" if it still don't work.

an alternative would be to iterate through a file (the html page) finding as start code and endcode and extracting inbetween....

//start vars
$startcode=" ";
$endcode=" ";
$pos=0;
$url="http://www.somewhere.com";

//get remote html and put into readable file
$url=file($url);
$file=implode('', $url);

// find startcode position
$startcodelength=strlen($startcode);
$startpos=strpos($file, $startcode, $pos);

//find end position
$endpos=strpos($file, $endcode, $startpos);
$textlength=$endpos-$startpos-$startcodelength;

//get text in between tags
$text=substr($file, $startpos+$startcodelength, $textlength);
$pos=$endpos;

now you have your pointer set to the end of the last so you can call the [function] again and iterate through it till you find no more....

btw - code not checked for full syntax etc - just pulled it from some of a function I have
