XslConnector
for the Microsoft SOAP Toolkit
|
|
XslConnector is a COM component that
integrates with the Microsoft SOAP Toolkit. It implements the
SoapConnector interface, so it is a replacement for the HTTP transport
bindings that the Toolkit provides. XslConnector allows you to
specify a local XSL document to be used to transform the message into a
response. I got the idea for this object from Don Box's SOAP example
where he describes SOAP as "XSLT with a longer wire".
I built this object to use as a testing
tool. You can set up an XSL document to generate Faults, or to
simulate certain responses, without having to go to a lot of
trouble. It helps isolate payload processing errors from transport
binding errors. To see how you can build SOAP endpoints using XSL, check out
Kafka.
I have included a piece of sample code
below that uses the XslConnector object. For more information on the
Microsoft SOAP Toolkit, click here.
Dim Serializer As SoapSerializer
Dim Reader As SoapReader
Dim Connector As SoapConnector
Set Connector = New XslConnector
'Use a local XSL document to generate the response
Connector.Property("XSL") = "d:\projects\soapplus\fancy.xsl"
Connector.Connect Nothing
Connector.BeginMessage Nothing
Set Serializer = New SoapSerializer
Serializer.Init Connector.InputStream
Serializer.startEnvelope
Serializer.startBody
Serializer.startElement "TestMethod", "http://www.topxml.com", , "v"
Serializer.startElement "A"
Serializer.writeString "1"
Serializer.endElement
Serializer.startElement "B"
Serializer.writeString "2"
Serializer.endElement
Serializer.endElement
Serializer.endBody
Serializer.endEnvelope
Connector.EndMessage
Set Reader = New SoapReader
b = Reader.Load(Connector.OutputStream)
If Not Reader.Fault Is Nothing Then
MsgBox Reader.faultstring.Text, vbExclamation
Else
MsgBox Reader.RPCResult.Text
End If
End Sub

XslConnector
is free. There is currently no install program, just
download the SoapPlus DLL and register it on your machine. I am
working separately on some other extensions to the Toolkit that will
provide additional help with testing and other areas of development, and
these will probably be bundled with the SoapPlus DLL in the future.
If you do download XslConnector, please sign up for our discussion
group get
notified of more SOAP developments at TopXML. Also, if you come
up with any great XSL documents for testing, please share them with me and
the rest of the developers using the SOAP Toolkit.
