Demonstrates how to call PostXml to call a SOAP web service. PowerBuilder

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

//  --------------------------------------------------------------------------------
//  Also see Chilkat's Online WSDL Code Generator
//  to generate code and SOAP Request and Response XML for each operation in a WSDL.
//  --------------------------------------------------------------------------------

//  This example uses a live web service at:
//  http://www.webservicex.net/uklocation.asmx
//  It gets the UK town,Postcode and County by Postcode(First Section of Post Code)

//  The SOAP XML will look like this:
//  <?xml version="1.0" encoding="utf-8"?>
//  <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
//    <soap:Body>
//      <GetUKLocationByPostCode xmlns="http://www.webserviceX.NET">
//        <PostCode>string</PostCode>
//      </GetUKLocationByPostCode>
//    </soap:Body>
//  </soap:Envelope>

//  For this example's sake, we'll load the XML from a file.  We'll test using PostCode "E3".  
//  The SOAP XML for this example may be downloaded from:
//  http://www.chilkatsoft.com/testData/ukPostCodeSoap.xml
loo_Xml = create oleobject
li_rc = loo_Xml.ConnectToNewObject("Chilkat.Xml")
if li_rc < 0 then
    destroy loo_Xml
    MessageBox("Error","Connecting to COM object failed")
    return
end if
li_Success = loo_Xml.LoadXmlFile("ukPostCodeSoap.xml")
if li_Success = 0 then
    Write-Debug loo_Xml.LastErrorText
    destroy loo_Xml
    return
end if

ls_StrXml = loo_Xml.GetXml()

loo_Http = create oleobject
li_rc = loo_Http.ConnectToNewObject("Chilkat.Http")

//  We'll need to add this in the HTTP header:
//  SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
loo_Http.SetRequestHeader("SOAPAction","http://www.webserviceX.NET/GetUKLocationByPostCode")

//  The endpoint for this soap service is:
ls_EndPoint = "http://www.webservicex.net/uklocation.asmx"

//  Note: This particular web service was live and functioning at the time this example
//  was written.  It is possible that as time progresses, this web service will no longer
//  be availble...
loo_Resp = create oleobject
li_rc = loo_Resp.ConnectToNewObject("Chilkat.HttpResponse")

li_Success = loo_Http.HttpStr("POST",ls_EndPoint,ls_StrXml,"utf-8","text/xml",loo_Resp)
if li_Success = 0 then
    Write-Debug loo_Http.LastErrorText
    destroy loo_Xml
    destroy loo_Http
    destroy loo_Resp
    return
end if

li_ResponseStatusCode = loo_Resp.StatusCode
//  You may wish to verify that the responseStatusCode equals 200...
Write-Debug "Response Status Code: " + string(li_ResponseStatusCode)

//  You may examine the exact HTTP header sent with the POST like this:
Write-Debug "LastHeader:"
Write-Debug loo_Http.LastHeader

//  Examine the XML returned by the web service:
Write-Debug "XML Response:"
loo_XmlResp = create oleobject
li_rc = loo_XmlResp.ConnectToNewObject("Chilkat.Xml")

loo_XmlResp.LoadXml(loo_Resp.BodyStr)
Write-Debug loo_XmlResp.GetXml()
