Matching regular expression

Question

I am trying to get the data from all the div's with price in them in the following section of code:

<section data-v-7630ac7c="" view-more-component="">

The regular expression i am using is

<div (..................) price="" (.*)">(.*)<\/div>

But I keep getting NULL. Any help will be really appreciated.

Answer 1

Although parsing html with regex is strongly discouraged your posted html code only contains div tags without nesting so you can apply this simple regex and do your job of getting all prices from div tags:

<div.*?price.*?>(\d+\.\d+)<\/div>

But keep this as a temporary fix and if you have to use it in long run then go for an html parser.

I tried both they didnt work here is the whole code i am using

<?
$curl = curl_init();
$SearchString = "BTCCAD";
$url = "https://einstein.exchange/trade?mode=advanced&instrument=$SearchString";
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
$result = curl_exec($curl);
preg_match_all('<div[^>]+price=\"\"[^>]+>([\d.]+)<',$result,$matches);
var_dump($matches);
curl_close($curl);
?>
