Using PHP and SoapClient.
I need to pass the following XML into a soap request - i.e. multiple \'s within .
I also ran into this issue calling soap with an parameter as an array. My array has to start with index 0 for it to work.
$client->__soapCall(my_function_name, [ 'body' => [ 'date' => '201930', 'ids' => [0 => '32001', 1 => '32002'], ], ]);
