Sven, that use case was one reason to implement mustache. I use it to generate SOAP calls from templates. As Mustache can have nested objects in processing you could even have more complex SOAP calls. Although complex/nested SOAP calls are far from being a good idea. Norbert

We have no SOAP implementation in Pharo (yet). But that does not mean we cannot do simple SOAP calls. Here is a practical example: checking the validity of a EU VAT number.
This is a public service offered by the EU through a SOAP API. The WSDL can be found here: http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl
From this we know that the endpoint is http://ec.europa.eu/taxation_customs/vies/services/checkVatService
When you paste the WSDL URL in http://wsdlbrowser.com you can explore the API (this site parses the WSDL to reveal its contents). The call that we need is called 'checkVat'. We can copy the call template and POST it to the endpoint, manually. If we load the XML Parser, we can interpret the result.
Here is the complete code:
| xml result | xml := ZnEntity with: ( '<?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:ec.europa.eu:taxud:vies:services:checkVat:types"> <SOAP-ENV:Body> <ns1:checkVat> <ns1:countryCode>{1}</ns1:countryCode> <ns1:vatNumber>{2}</ns1:vatNumber> </ns1:checkVat> </SOAP-ENV:Body> </SOAP-ENV:Envelope>' format: #('LU' '20165772')) type: ZnMimeType applicationXml. result := ZnClient new url: 'http://ec.europa.eu/taxation_customs/vies/services/checkVatService'; entity: xml; contentReader: [ :entity | XMLDOMParser parse: entity contents ]; post. ((result allElementsNamed: 'checkVatResponse') first elementsCollect: [ :each | each name -> each contentString ]) asDictionary.
=>
a Dictionary( 'address'->'31, RUE STE ZITHE L-2763 LUXEMBOURG' 'countryCode'->'LU' 'name'->'ITUNES S.A R.L.' 'requestDate'->'2015-03-03+01:00' 'valid'->'true' 'vatNumber'->'20165772' )
Of course, this will only work with simple SOAP interfaces.
