使用php Simple HTML DOM Parser

Question

how do I capture, just the names of the animals.

my zoo.xml

<?xml version="1.0" encoding="UTF-8"?>
<zoo>
<animal id="315" name="Lion"></animal>
<animal id="316" name="Cat"></animal>
</zoo>

I did the test like this, but it returns empty.

edit.

  $html = file_get_html('zoo.xml');
  foreach($html->find('animal') as $animal) {
            $item['name'] = $animal->find('name',0 )->plaintext;
            $animals[] = $item;
        }
        print_r($animals);

result

   Array
(
    [0] => Array
        (
            [name] => 
        )

    [1] => Array
        (
            [name] => 
        )

)

Am I doing the right way?

Answer 1

The animal names are in the attributes, you can use getAttribute:

$html = file_get_html('zoo.xml');
foreach($html->find('animal') as $animal) {
    $animals[] = ['name' => $animal->getAttribute('name')];
}
print_r($animals);

Result:

Array
(
    [0] => Array
        (
            [name] => Lion
        )

    [1] => Array
        (
            [name] => Cat
        )

)
