About XPATH ARRAY expressions

Question

Invoking "capescience.GlobalWeather" I have to compose 2 services in two different port Type of the same partnerLink.
First One to retrieve the local CODE of an Airport, second one to use thise code to invoke Weather Report of the Weather Station of the airport...
The GlobalWeather.WSDL is without a SCHEMA, so ican't use the wizards.
Searching StationInfo By Name of the City Airport I recieve an ArrayOfStation, so in first invocation of WS my SOAP response is just like:
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"

</item>
<item>...</item>
<item>...</item>
</return>
</cc2:searchByNameResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Answer 1

Does not works with the folowing message:
Error in <assign> expression: <from> value is empty at line "57". The XPath expression : "/GlobalWeather:return/GlobalWeaher:Item[1]/GlobalWeather:wmo" returns zero node, when applied to document shown below:
