Small recent example from xTee:

Request:

<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xtee="http://x-tee.riik.ee/xsd/xtee.xsd" xmlns:ehis="http://producers.ehis.xtee.riik.ee/producer/ehis">
   <soapenv:Header>
      <xtee:id xsi:type="xsd:string">680e0c731a244e2c91210e1540458441</xtee:id>
      <xtee:nimi xsi:type="xsd:string">ehis.idpilet</xtee:nimi>
      <xtee:isikukood xsi:type="xsd:string">10101010101</xtee:isikukood>
      <xtee:andmekogu xsi:type="xsd:string">ehis</xtee:andmekogu>
      <xtee:asutus xsi:type="xsd:string">10747013</xtee:asutus>
   </soapenv:Header>
   <soapenv:Body>
      <ehis:idpilet soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

      </ehis:idpilet>
   </soapenv:Body>
</soapenv:Envelope>

Answer:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

      <ns1:idpiletResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="http://producers.ehis.xtee.riik.ee/producer/ehis">
         <paring xsi:type="ns1:EHIS_Isikukood">10101010101</paring>
         <keha xsi:type="ns1:EHIS_Boolean">ei</keha>
      </ns1:idpiletResponse>
   </soapenv:Body>
</soapenv:Envelope>

SOAP further explanations

Good explanatory stuff from simpler to more complex:

SOAP extra tech

NB! There will be no concrete questions about SOAP extra tech except basic understanding as to what do the words mean.

Stuff often used with SOAP: describing services (wsdl), service catalogue (uddi), additional interoperability standards (WS-I).

If worried, read "s stands for simple" first.

A detailed demo of SOAP and WSDL stuff with all the tiniest details can be found at the gsoap toolkit site. The demo WSDL used in the live examples is also quite readable.

WSDL

A detailed but partly almost readable w3c primer: http://www.w3.org/TR/wsdl20-primer/. You may also have a look at the old version primer.

A fairly good presentation explaining WSDL: Fail:WSDL.pdf

UDDI

WS-I stuff

Read the wikipedia overview and have a brief look at the ws-i official site.
