解析XML，使用SimpleXMLElement在PHP中获取节点

Question

I have to convert XML file from my supplyer to CSV version (for Magento Store).

I wrote simple php script to do that, but I cant figure it out why its not working (i have other supplyers, but their XML version is much simpler.

But to the point:

Im have this XML

<pasaz:Envelope xmlns:pasaz="http://schemas.xmlsoap.org/soap/envelope/">
    <pasaz:Body>
        <loadOffers xmlns="urn:ExportB2B">
            <offers>
                <offer>
                    <id>9</id>
                    <name>

            </offers>
        </loadOffers>
    </pasaz:Body>
</pasaz:Envelope>

And im using this script:

$plik=file_get_contents('kolba.xml');
$plik=utf8_encode($plik);
$movies = new SimpleXMLElement($plik);
$stala_czesc='"admin";"base";"Default";"simple";'; 
$stala_czesc2=';"Żaden";0.0000;';
$stala_czesc3='"Not Visible Individually";1;"Włączone"'."
";   
foreach ($movies->offer as $product) 
{
    //echo '<br>Przetwarzam';
    $wynik="";
    $wynik=$stala_czesc;
    $nazwa=$product->name;
    $nazwa=str_replace('"',"",$nazwa);
    $nazwa = preg_replace("/[^[:alnum:][:punct:] -]/","",$nazwa);
    $wynik.='"'.$product->id.'_kolba";"'.$nazwa.'";
    '.number_format(intval($product->price),4,'.','').';
    '.number_format(intval($product->price),4,'.','').';
    '.number_format(intval($product->price),4,'.','').$stala_czesc2.$product->availability.';'.$stala_czesc3;
    echo '<br>';
    echo $wynik;
}

But FOR iterator never starts, why?

Answer 1

The problem you are experiencing is because of the namespaced Envelope/Body, here's a dirty hack to get to your data atleast;

$movies = new SimpleXMLElement($plik);
$movies = $movies->children('http://schemas.xmlsoap.org/soap/envelope/');
$offers = $movies->children()->loadOffers->offers;

and to loop the offers

foreach ($offers->offer as $product) { .. }
