I have a WSDL that has an element that requires an attribute:
<xsd:complexType name="claim"> <xsd:annotation> <xsd:documentation>Claim Element</xsd:documentation> </xsd:annotation> <xsd:sequence> <!-- other elements removed --> </xsd:sequence> <xsd:attribute name="claimId" type="xsd:nonNegativeInteger" use="required" /> </xsd:complexType> In terms of generated xml, it should look like:
<claims> <claim claimId="1"> <!-- elements removed --> </claim> <!-- more claims --> </claims> Within a foreach loop I am putting together an array of elements and using the attribute as part of the key:
//$claim = array of key/value pairs $claim = [...]; $claim = new \SoapVar($claim, SOAP_ENC_OBJECT, null, null, 'claim claimId="' . ($key+1) . '"'); $claims['claim claimId="'.($key+1).'"'] = $claim; When it comes to passing this to the SoapClient, the elements get removed:
//$client = new \SoapClient($wsdl); $client->checkClaims($claims); But all I'm getting is:
<claims /> How do I get my soap client to parse the claim elements correctly in the soap call?

So there are few issues with your code. For this to work, you need to use the SoapClient in WSDL mode ($client = new \SoapClient($wsdl);, which you are doing). Next below is wrong
$claim = [...]; $claim = new \SoapVar($claim, SOAP_ENC_OBJECT, null, null, 'claim claimId="' . ($key+1) . '"'); $claims['claim claimId="'.($key+1).'"'] = $claim; You don't add attributes using 'claim claimId="' . ($key+1) . '"'.
Now what you need is to use a classmap. Below is a sample python flask app I created to show the WSDL
from flask import Flask app = Flask(__name__) @app.route("/ICalculator",methods=['get', 'post']) def reply(): return "<xmldata />" @app.route("/app.wsdl") def send(): return """<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:wsa10="http://www.w3.org/2005/08/addressing" xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" targetNamespace="http://localhost:5001" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"> <wsdl:types> <xsd:schema targetNamespace="http://localhost:5001" elementFormDefault="qualified" > <xsd:element name="Claim"> <xsd:complexType> <xsd:sequence> <xsd:element minOccurs="0" name="a" type="xsd:int" /> <xsd:element minOccurs="0" name="b" type="xsd:int" /> </xsd:sequence> <xsd:attribute name="claimId" type="xsd:nonNegativeInteger" use="required" /> </xsd:complexType> </xsd:element> <xsd:element name="AddResponse"> <xsd:complexType> <xsd:sequence> <xsd:element minOccurs="0" name="result" type="xsd:int" /> </xsd:sequence> </xsd:complexType> </xsd:element> </xsd:schema> </wsdl:types> <wsdl:message name="ICalculator_Add_InputMessage"> <wsdl:part name="parameters" element="tns:Add" /> </wsdl:message> <wsdl:message name="ICalculator_Add_OutputMessage"> <wsdl:part name="parameters" element="tns:AddResponse" /> </wsdl:message> <wsdl:portType name="ICalculator"> <wsdl:operation name="Add"> <wsdl:input wsaw:Action="http://localhost:5001/ICalculator/Add" message="tns:ICalculator_Add_InputMessage" /> <wsdl:output wsaw:Action="http://localhost:5001/ICalculator/AddResponse" message="tns:ICalculator_Add_OutputMessage" /> </wsdl:operation> </wsdl:portType> <wsdl:binding name="DefaultBinding_ICalculator" type="tns:ICalculator"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http" /> <wsdl:operation name="Add"> <soap:operation soapAction="http://localhost:5001/ICalculator/Add" style="document" /> <wsdl:input> <soap:body use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="CalculatorService"> <wsdl:port name="ICalculator" binding="tns:DefaultBinding_ICalculator"> <soap:address location="http://localhost:5001/ICalculator" /></wsdl:port> </wsdl:service> </wsdl:definitions> """.replace(r"\r", "").replace(r"\n", "") if __name__ == "__main__": app.run(debug=True, host='0.0.0.0', port=5000) Then ran the same using
python3 wsdl.py And ran another socat to view the traffic
socat -v TCP-LISTEN:5001,fork TCP:127.0.0.1:5000 Next I wrote a sample PHP code to show how classmap works
<?php class Claim { public function __construct(Array $properties=array()){ foreach($properties as $key => $value){ $this->{$key} = $value; } } } $test = new Claim(array('claimId'=>10, 'a'=> 22, 'b'=> 33)); $claim=new SoapVar($test, SOAP_ENC_OBJECT); $wsdl = "http://localhost:5001/app.wsdl"; $client = new SoapClient($wsdl, array( 'trace' => 1, 'encoding' => 'UTF-8', 'soap_version' => SOAP_1_1, 'classmap' => array('Claim' => 'Claim') )); $client->add($claim); And the resultant xml is
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://localhost:5001" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><SOAP-ENV:Body><parameters claimId="10" xsi:type="ns1:Claim"><ns1:a>22</ns1:a><ns1:b>33</ns1:b></parameters></SOAP-ENV:Body></SOAP-ENV:Envelope>

Knowing that \SoapClient can accept an xml string, I decided to convert my array of data into an xml string:
/** * Convert an array to an xml. Recursive function. * @param array $array * @param String $rootElement OPTIONAL name of root element. * @param \Simple XMLElement $xml OPTIONAL * @return String */ function arrayToXml($array, $rootElement = null, $xml = null) { $_xml = $xml; if ($_xml === null) { $_xml = new \SimpleXMLElement($rootElement !== null ? $rootElement : '<root/>'); } foreach ($array as $k => $v) { if (is_array($v)) { //nested array arrayToXml($v, $k, $_xml->addChild($k)); } else { $_xml->addChild($k, $v); } } //Remove xml doctype and root name spaces. return str_replace(["<?xml version=\"1.0\"?>\n", '<root>', "</root>\n"], '', $_xml->asXML()); } //my array of claims $claims = [ 'claim claimId="1"' => [ //... ], 'claim claimId="2"' => [ //... ], //... ]; $claims = arrayToXml($claims); This generates an xml string of:
<claim claimId="1"><!-- stuff --></claim claimId="1"><claim claimId="2"><!-- stuff --></claim claimId="2"> Next step is to remove the attribute from the closing tags:
$claims = preg_replace('#</claim claimId="\d+">#', '</claim>', $claims); Finally, I wrap my xml in the appropriate parameter name and convert it to a \SoapVar so the \SoapClient will parse it correctly:
$claims = '<ns1:claims>' . $claims . '</ns1:claims>'; $claims = new \SoapVar($claims, XSD_ANYXML, 'http://www.w3.org/2001/XMLSchema-instance'); Passing $claims into my \SoapClient and running var_dump($client->__getLastRequest()); shows my generated xml as:
<?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.w3.org/2001/XMLSchema-instance"><SOAP-ENV:Body><ns1:claims><claim claimId="1"><!--stuff--></claim><claim claimId="2"><!--stuff--></claim></ns1:claims></SOAP-ENV:Body></SOAP-ENV:Envelope> Just as it wanted.
