<meta property="twitter:player:stream" content="https://v.cdn.vine.co/v/videos/8B474922-0D0E-49AD-B237-6ED46CE85E8A-118-000000FFCD48A9C5_1.0.6.mp4?versionId=ul2ljhBV28TB1dUvAWKgc6VH0fmv8QCP">
I want to take only the content of the these meta tags. if anyone can help really appreciate it. Thanks

Instead of using the lib you pointed out, I'm using native PHP DOM in this example, and it should work.
Here's a small class I created for something like that:
<?php
class DomFinder {
function __construct($page) {
$html = #file_get_contents($page);
$doc = new DOMDocument();
$this->xpath = null;
if ($html) {
$doc->preserveWhiteSpace = true;
$doc->resolveExternals = true;
#$doc->loadHTML($html);
$this->xpath = new DOMXPath($doc);
$this->xpath->registerNamespace("html", "http://www.w3.org/1999/xhtml");
}
}
function find($criteria = NULL, $getAttr = FALSE) {
if ($criteria && $this->xpath) {
$entries = $this->xpath->query($criteria);
$results = array();
foreach ($entries as $entry) {
if (!$getAttr) {
$results[] = $entry->nodeValue;
} else {
$results[] = $entry->getAttribute($getAttr);
}
}
return $results;
}
return NULL;
}
function count($criteria = NULL) {
$items = 0;
if ($criteria && $this->xpath) {
$entries = $this->xpath->query($criteria);
foreach ($entries as $entry) {
$items++;
}
}
return $items;
}
}
To use it you can try:
$url = "https://vine.co/v/bjHh0zHdgZT";
$dom = new DomFinder($url);
$content_cell = $dom->find("//meta[#property='twitter:player:stream']", 'content');
print $content_cell[0];
