Get data from URL based on the data inside span - php

Question

I am trying to get data from a URL and only retrieve the data from within the span that has title=""
Each "row" of data has a span with a different incremental value of the title for example
title="1", title="2"
so the data I want to get will be inside this span
DATA HERE
x will be an incremental number
I am able to get all data from the page using this code however I am stuck on how to achieve what i need
function file_get_contents_curl($url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$html = file_get_contents_curl("http://www.example.com");
//parsing all content:
$doc = new DOMDocument();
#$doc->loadHTML($html);
echo "$html";
The data is formatted like :
<span id="RANDOMINFO">
+
<span title="1">DATA I WANT HERE</span>
CLICK
RANDOM DATA
</span>
<span id="RANDOMINFO">
+
<span title="2">DATA I WANT HERE</span>
CLICK
RANDOM DATA
</span>

Solution:
Explanation is available as comments in the provided code
$doc = new DOMDocument();
#$doc->loadHTML($html);
foreach($doc->getElementsByTagName('span') as $element ) { //Loops through all available span elements
if (empty($element->attributes->getNamedItem('id')->value) || $element->attributes->getNamedItem('id')->value != 'RANDOMINFO') { // Discards irrelevant span elements based on their `ID`. A similar sorting is achieved with `empty()` as the target `span` doesn't have any associated `ID`.
echo get_inner_html($element).PHP_EOL;
}
}
function get_inner_html( $node ) {
$innerHTML= '';
$children = $node->childNodes;
foreach ($children as $child) {
$innerHTML .= $child->ownerDocument->saveHTML( $child ); //fetches the text inside child elements of the targeted element
}
return $innerHTML;
}
Output:
DATA I WANT HERE
DATA I WANT HERE
