osx - How can I make AppleScript SOAP work with existing SOAP webservices (e.g. W3Schools' CelsiusToFarenheit example)? -

i'm using applescript editor. run following code there:

tell application "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl"     call soap {method name:"celsiustofahrenheit", method namespace uri:"http://www.w3schools.com/webservices/", parameters:{celsius:50 string}, soapaction:"http://www.w3schools.com/webservices/celsiustofahrenheit"} end tell 

if execute above code, "error" string (which not expected). generated request follows:

<?xml version="1.0" encoding="utf-8"?>   <soap-env:envelope     xmlns:xsd="http://www.w3.org/1999/xmlschema"     xmlns:xsi="http://www.w3.org/1999/xmlschema-instance"     soap-env:encodingstyle="http://schemas.xmlsoap.org/soap/encoding/"     xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/"     xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/">       <soap-env:body>         <m:celsiustofahrenheit xmlns:m="http://www.w3schools.com/webservices/">           <celsius xsi:type="xsd:int">50</celsius>         </m:celsiustofahrenheit>       </soap-env:body>     </soap-env:envelope> 

if edit request (i used fiddler edit request):

<?xml version="1.0" encoding="utf-8"?>       <soap-env:envelope         xmlns:xsd="http://www.w3.org/1999/xmlschema"         xmlns:xsi="http://www.w3.org/1999/xmlschema-instance"         soap-env:encodingstyle="http://schemas.xmlsoap.org/soap/encoding/"         xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/"         xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/">           <soap-env:body>             <celsiustofahrenheit xmlns="http://www.w3schools.com/webservices/">               <celsius xsi:type="xsd:int">50</celsius>             </celsiustofahrenheit>           </soap-env:body>         </soap-env:envelope> 

1. change "m:celsiustofarenheit" "celsiustofarenheit"
2. change "xmlns:m" "xmlns"

i receive "122" correct response.

my questions are:

1. why happening? soap format used "call soap" function old format?
2. is there way fix (e.g. remove ":m" or "m:" in request or use different soap format through code setting parameter in "call soap" method [i don't know if possible])?

the skinny:

• a bug in call soap feature neglects namespace-tag parameters given call properly: method name element prefixed m:, parameter elements not.

• the workaround explicitly prefix parameter names m:; in above example, use |m:celsius| instead of celsius - note enclosing | signs needed can use name otherwise break parsing.

caveat: there chance workaround break should apple ever fix bug.

applying workaround above example gives us:

tell application "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl"   call soap {method name:"celsiustofahrenheit", ¬             method namespace uri:"http://www.w3schools.com/webservices/", ¬             parameters:{|m:celsius|:50 string}, ¬             soapaction:"http://www.w3schools.com/webservices/celsiustofahrenheit"} end tell

background:

1. (...) soap format used "call soap" function old format?

the short of it: applescript uses soap 1.1 schema, , while apis under hood support soap 1.2, cannot select applescript ((you can from c using carbon))

as described above, soap xml construction has bug, reason call didn't work. (the web service @ http://www.w3schools.com/webservices/tempconvert.asmx support 1.1, alongside 1.2).

here clues regarding importance , maintenance status of call soap , call xml-rpc features:

• the features described in documentation separate applescript language guide, though appear part of language (could not find them in external dictionaries)

• the documentation written in 2001 (as of osx 10.1; , has seen tiny revision in 2005; warning of potentially outdate web-service url added :)).

'2. there way fix (e.g. remove ":m" or "m:" in request or use different soap format through code setting parameter in "call soap" method?

(see workaround above.)

based on documentation-status clues, not hold breath updates or fixes apple - pity, because these features handy.
