Fetching First value from nodeValue using DOMDocument in PHP

Hi,
I have the following code that uses DOMDocument to get some data from a html string in PHP.

Code: Select all

// string with HTML content
$strhtml = '<div class="dv1">Nr. 123
<div>Website: <span> https://coursesweb.net/ </span></div>
<div>';

// create the DOMDocument object, and load HTML from string
$dom = new DOMDocument();
$dom->loadHTML($strhtml);

$data = '';
// get data from the Div with class 'dv1'
foreach($dom->getElementsByTagName('div') as $el) {
  if($el->getAttribute('class') == 'dv1') {
    $data = $el->nodeValue;
  }
}
echo $data;  // Nr. 123 Website: https://coursesweb.net/    
- I have to get the first part from that div, the value: "Nr. 123", but it is fetching the whole nodeValue of the Div class "dv1".
How can I get the first string from that Div, without the other texts in the whole nodeValue?
Thanks.

Hi,
The nodeValue attribute gives you the combined text of all the child nodes.
To get the text value of the first child text node only, use: firstChild->nodeValue.
Change your code to:

Code: Select all

$data = $el->firstChild->nodeValue;
