I need to generate the following XML with SOAP:
<MetaDataConstraint class="topics">
<Value>FRX</Value>
</MetaDataConstraint>
I am not sure how to generate the attributes.
Based on: Using SOAP to generate XML attributes in PHP, I tried to do the following, but unfortunatelly it does not work.
$myFilter = array("MetaDataConstraint" => array("_" => array("Value" => "FRX")), "class" => "topics");
How can I solve it ?
