How can the issue of only one iteration occurring in the inner foreach loop be resolved to ensure all child nodes are successfully removed from elements with a "typ" attribute?

The issue of only one iteration occurring in the inner foreach loop can be resolved by using the reference symbol "&" before the $child variable in the loop declaration. This allows the loop to directly modify the elements in the original array, ensuring that all child nodes are successfully removed from elements with a "typ" attribute.

// Iterate over each element with a "typ" attribute
foreach ($xml->xpath('//*[@typ]') as $element) {
    // Iterate over each child node of the current element
    foreach ($element->children() as &$child) {
        // Remove the child node
        unset($child);
    }
}
