在php中获取xml名称空间属性

Question

is it possible to get the attribute: name="Total" and the value ? I know it's possible in an array, but the row is not always the same.

This is the XML:

<XML>
<resultaten>
<resultaat>
<id>3123709</id>
<antwoord name="Total">9,0</antwoord>
<antwoord name="Communicatie">9,0</antwoord>
<antwoord name="Advies">9,0</antwoord>
<antwoord name="Deskundigheid">9,0</antwoord>
<antwoord name="Betrokkenheid">9,0</antwoord>
<antwoord name="Gemiddelde">9,0</antwoord>
</resultaat>
</resultaten>
</XML>

And i tried this:

$xml = simplexml_load_file($url)

$date = $xml->resultaten->resultaat->attributes();
echo $date;

Answer 1

I do not use simplexml so cannot advise on it's methods but using the standard DOMDocument and it's associated methods it is fairly trivial to get the name attribute values from the XML you show in the question.

$xml='<XML>
    <resultaten>
        <resultaat>
            <id>3123709</id>
            <antwoord name="Total">9,0</antwoord>
            <antwoord name="Communicatie">9,0</antwoord>
            <antwoord name="Advies">9,0</antwoord>
            <antwoord name="Deskundigheid">9,0</antwoord>
            <antwoord name="Betrokkenheid">9,0</antwoord>
            <antwoord name="Gemiddelde">9,0</antwoord>
        </resultaat>
    </resultaten>
</XML>';


$dom=new DOMDocument;
$dom->loadXML( $xml );
$col=$dom->getElementsByTagName('antwoord');
foreach( $col as $node )echo $node->getAttribute('name') . '<br />';

outputs:

Total
Communicatie
Advies
Deskundigheid
Betrokkenheid
Gemiddelde

update

To use a url as opposed to a string simply use the load method as below.

    $url='https://klantenvertellen.nl/xml/van_essen_advocaten';
    $dom=new DOMDocument;
    $dom->load( $url );
    $col=$dom->getElementsByTagName('antwoord');
    foreach( $col as $node )echo $node->getAttribute('name') . '<br />';

outputs:

datum
referentie
Uw voornaam/bedrijf:
Aanbeveling:
Geholpen door:
Ervaring:
Totaal oordeel
Communicatie
Advies
Deskun....etc

Answer 2

To use SimpleXML as you originally wanted is well - simple. If you just want the Total value, then you can use XPath to say get the antwoord element with the name attribute which has a value of Total . The xpath() call returns a list of matching elements, so use [0] to get the first one. Also this returns a SimpleXMLElement, so to ensure the value is a string - cast it to (string) before using the value...

$xml = simplexml_load_file($url);

$total = $xml->xpath("//antwoord[@name='Total']")[0];
echo (string)$total;

gives...

9,0
