I have a html like below:
<table>
<thead>
<tr>
<th>Name</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<tr>
<td>ABC</td>
<td><a data-permission="allow"></a></td>
</tr>
<tr>
<td>B</td>
<td><a data-permission="allow"></a></td>
</tr>
<tr>
<td>C</td>
<td><a data-permission="allow"></a></td>
</tr>
<tr>
<td>D</td>
<td><a data-permission="allow"></a></td>
</tr>
<tr>
<td>E</td>
<td><button type="button" data-permission="allow"></button></td>
</tr>
</tbody>
</table>
Now i am finding the nodes who contains "data-permission" attributes like (a, button etc.) from above example.
TO do that i am using the below code. Now what i am trying do is remove that whole <a>..</a> or <button>...</button> or any other element if they contain "data-permission" attribute and after deletion only return remaining HTML. So how to achieve that?
$dom = new DOMDocument;
$dom->loadHTML($output);
$xpath = new DOMXPath($dom);
$nodes = $xpath->query('//@data-permission-id');
foreach ($nodes as $node) {
echo $node->nodeValue;
//$node->parentNode->removeChild($node); throws the error "Not Found Error"
}
Note- I have tried $node->parentNode->removeChild($node); inside loop, but it throws the error. Also after delete that tag, i want to get remaining HTML. I have read the How to delete element with DOMDocument? but it doesn't help.
Replace your node value to remove : $node->nodeValue = "";
$dom = new DOMDocument;
$dom->loadHTML($output);
echo "Previous : ".PHP_EOL.$dom->textContent.PHP_EOL;
$xpath = new DOMXPath($dom);
$nodes = $xpath->query("//*[@data-permission='allow']");
foreach ($nodes as $node) {
$node->nodeValue = "";
$dom->saveHTML();
}
