Simpe_html_dom：如何删除具有特定“class”属性的'div'标签？

Question

How can remove all the div tags with the class attribute equal to info in a PHP page, i.e. the <div class="info">...</div> tags need to be removed from an HTML string.

I have seen this question, but I want to remove elements with the class equal to info.

I will like to use Simple HTML DOM (compared to any other library) because I am already using it in the program.

Answer 1

There are multiple ways to select elements by class. Check out the manual.

$html->find('div[class=info]');
$html->find('div.info');
$html->find('.info'); // not just divs

Then using this answer, you can remove the elements by setting outertext to be blank. In a loop it might look like this:

foreach($html->find('div.info') as $node) {
    $node->outertext = '';
}

Edit: this is a good article which seems to cover most aspects of manipulation and common pitfalls (including deleting data).
