I´m trying to extract the RecordID = "1014276" from a tag
I tried with :
$result = curl_exec($ch);
curl_close($ch);
$xml2 = simplexml_load_string($result);
echo $latitude = (string) $xml2['RecordID'];
This is the XML response:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soap:Body>
<ns1:createDataResponse xmlns:ns1="http://3e.pl/ADInterface">
<StandardResponse RecordID="1014276" xmlns="http://3e.pl/ADInterface"/>
</ns1:createDataResponse>
</soap:Body>
</soap:Envelope>
You can apporach this as
$xml = '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soap:Body>
<ns1:createDataResponse xmlns:ns1="http://3e.pl/ADInterface">
<StandardResponse RecordID="1014276" xmlns="http://3e.pl/ADInterface"/>
</ns1:createDataResponse>
</soap:Body>
</soap:Envelope>';
$p = xml_parser_create();
xml_parse_into_struct($p, $xml, $values, $index);
xml_parser_free($p);
echo $values[3]['attributes']['RECORDID'];
This involves a bit more than just accessing the attribute, first you have to select the correct element. Using XPath is the most comment way in this sort of structure. As this has a default namespace defined for the data, you will need to register this with the SimpleXMLElement first (using $xml2->registerXPathNamespace("ns1","http://3e.pl/ADInterface");
.
You can then find the element using the XPAth expression //ns1:StandardResponse
. As the xpath()
method returns a list of found elements, use [0]
to just extract the first match. You should then be able to extract the attribute as in your code using the resultant element...
$xml2 = simplexml_load_string($result);
$xml2->registerXPathNamespace("ns1","http://3e.pl/ADInterface");
$response = $xml2->xpath("//ns1:StandardResponse")[0];
echo (string) $response['RecordID'];
