That is correct, when you override __doRequest() it will be executed whenever you make a SOAP method call. You can then modify the payload with DOM or your preferred method. You just have to remember to call parent::__doRequest at the end to make sure the request is actually sent over the wire.

I don't think I'd recommend removing the xsi:type attributes, as they may be

I reviewed the SOAP 1.1 documentation at:

http://www.w3.org/TR/2000/NOTE-SOAP-20000508/#_Toc478383512

The examples given in section 5.4.2 (encoded arrays) make no mention of supplying the xsi:type attribute even though it does say that the type is SOAP-ENC:Array - although I only skimmed the docs quickly so I might have missed something. In any case, .NET seems to accept xsi:type="SOAP-ENC:Array" quite happily, so I would tend to agree with you.

There is no need to take such a risk, it is very easy to find the right namespace prefix:

$dom = DOMDocument::loadXML($request); $soapencPrefix = $dom->lookupPrefix('http://schemas.xmlsoap.org/soap/encoding/');

Of course, the workaround I posted also relies on xsi and SOAP-ENV being defined, so if you are concerned that the namespace prefixes generated by PHP might change, create a lookup table and use that instead:

public function __doRequest($request, $location, $action, $version) { // Namespace URIs and prefixes $nsURI = array( 'env' => 'http://schemas.xmlsoap.org/soap/envelope/', 'enc' => 'http://schemas.xmlsoap.org/soap/encoding/', 'xsi' => 'http://www.w3.org/2001/XMLSchema-instance'); $nsPrefix = array();

// Load request $dom = DOMDocument::loadXML($request); $xpath = new DOMXPath($dom);

// Find namespace prefixes foreach ($nsURI as $identifier => $namespaceURI) $nsPrefix[$identifier] = $dom->lookupPrefix($namespaceURI);

// Array serialisation: remove the xsi:type attribute from all arrays encoded using SOAP-ENC:arrayType // as this causes an "no type associated with Xml key"-type SOAP server error in .NET $nodes = $xpath->query("/{$nsPrefix['env']}:Envelope/{$nsPrefix['env']}:Body/*" . "//*[@{$nsPrefix['enc']}:arrayType and @{$nsPrefix['xsi']}:type]");

foreach ($nodes as $node) $node->setAttributeNS($nsURI['xsi'], "{$nsPrefix['xsi']}:type", "{$nsPrefix['enc']}:Array");

$request = $dom->saveXML();

return parent::__doRequest($request, $location, $action, $version); }

This will break if you try it on a SOAP 1.2 payload, at least because the SOAP-ENV namespace is different, and probably for other reasons too :-)
