I am seeking a way to eliminate specific html code from the data I am scraping, however, I am unable to isolate it by its id or class. It is necessary to erase every occurrence of this particular code within the html.
<ul data-bfa="@l:Subbuzz-Share;">
<!-- MORE CODES -- >
</ul>
If you want to remove a specific element from an HTML tag, you can use either str_replace or regex (regular expression) methods
For this example, let's start with using str_replace:
// Define a variable containing the html tag
$html = '
<ul data-bfa="@l:Subbuzz-Share;">
<!-- MORE CODES -- >
</ul>
';
// Remove the specified element using str_replace
$html = str_replace('data-bfa="@l:Subbuzz-Share;"','',$html);
For more information on str_replace, visit: https://www.php.net/manual/tr/function.str-replace.php
Now, let's explore using regex, which is versatile for various cases:
// Define a variable containing the html tag
$html = '
<ul data-bfa="@l:Subbuzz-Share;">
<!-- MORE CODES -- >
</ul>
';
// Remove the element using preg_replace and regex
$html = preg_replace('data-bfa=".+"','',$html);
// Another way to remove the element using regex
$html = preg_replace('data-.+=".+"','',$html);
For more information on preg_replace with regex, visit: https://www.php.net/manual/tr/function.preg-replace.php
Additionally, you can practice and test your regex patterns on this useful site:
Edit: To be more specific in removing the html tag type:
// Using str_replace may not be ideal for this scenario
$html = str_replace('<ul data-bfa="@l:Subbuzz-Share;">','<ul>',$html);
// Using preg_replace to remove the specified element
$html = preg_replace('(<ul )data-.+=".+"','$1',$html);
// Another way of using preg_replace to remove the element
$html = preg_replace('(<ul .+) data-.+=".+"','$1',$html);
If you find regex confusing, take some time to study and understand how it works :)
