Get h2 html using Simple HTML DOM Parser

Question

I have the HTML web page with this code:

<div class="col-sm-9 xs-box2">
    <h2 class="title-medium br-bottom">Your Name</h2>
</div>

Now I want to use Simple HTML DOM Parser to get the text value of h2 in this div. My code is:

$name = $html->find('h2[class="title-medium br-bottom"]');
echo $name;

But it always return an error: "

Notice: Array to string conversion in C:\xampp\htdocs\index.php on line 21
Array

How can I fix this error?

$name is not a string and you can't echo it. Try print_r maybe to check? — Eddie

Now with print_r($name), it's return "Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 65015808 bytes) in C:\xampp\htdocs\index.php on line 21" — ABCD

You need to use $name->plaintext. Check PHP Simple Html Dom get the plain text of div — Mohammad

One thing to be very careful about is when using class attributes to find data, they can be easily changed by the page developers and suddenly your code fails to load this data. — Nigel Ren

Can you try for Simple HTML DOM

 foreach($html->find('h2') as $element){
    $element->class;
 }

There are other methods to parse

Method 1.

You can get the H2 tags using the following code snippet, using DOMDocument and getElementsByTagName

$received_str = '<div class="col-sm-9 xs-box2">
  <h2 class="title-medium br-bottom">Your Name</h2>
</div>';
$dom = new DOMDocument;
@$dom->loadHTML($received_str);
$h2tags = $dom->getElementsByTagName('h2');
foreach ($h2tags as $_h2){
  echo $_h2->getAttribute('class');
  echo $_h2->nodeValue;
}

Method2

Using the Xpath you can parse it

$received_str = '<div class="col-sm-9 xs-box2">
    <h2 class="title-medium br-bottom">Your Name</h2>
</div>';
$dom = new DOMDocument;
$dom->loadHTML($received_str);
$xpath = new DomXPath($dom);
$nodes = $xpath->query("//h2[@class='title-medium br-bottom']");
header("Content-type: text/plain");
foreach ($nodes as $i => $node) {
    $node->nodeValue;
}
