I have used the following code to pull the racename and the time of the race

$url         = ""; 
$html        = file_get_contents($url);
$dom         = new DOMDocument();
@$dom->loadHTML($html);
$dom->preserveWhiteSpace = false;
$xpath                   = new DOMXPath($dom);
//pull the individual cards for the day
//li class="rac-cardsclass="ix ixc"
$getdropdown             = '//div[contains(@class, "tracks-list")]';
$getdropdown2            = $xpath->query($getdropdown);
//loop through each individual card
foreach ($getdropdown2 as $dropresults) {
echo $dropresults->textContent. "<br />";
}

What i would like to do is pull the meeting name if only the link (shown below) contains "GB" and "today" (this is within the class text) -

>  <a class="tag-i13n i13n-ltxt-meeting i13n-sec-GB i13n-tab-today"
> href="/exchange/plus/#/horse-racing/market/1.119408124">Lingfield</a>

so the outcome would be lingfield... if this is true i would like to then pull the time of the race and the market id from the following :

<a class="race-link  tag-i13n i13n-ltxt-race i13n-sec-GB i13n-tab-today"
        href="/exchange/plus/#/horse-racing/market/1.119408124"
        title="5f Nursery | 7 Runners">14:10</a>

so the outcome would be:

Lingfield 14:10 1.119408124 
Lingfield 14:40 1.119408144
 ............................. 
Wolverhampton 14:20 1.119408153
