Failing to send xml in the REST driver

Hi,

I'm trying to set up a REST-driver that will send its data as xml instead of JSON and I can't get it to work. Does anyone have an example of how a proper document should look like? The only example in the documentation uses JSON.

My attempt so far looks like this. Replacing the content of the value node with some JSON text and changing the content type to application/json works fine.

A bit of a shot in the dark... have you tried removing spaces and new lines from your value xml?  Perhaps put quotes around it so it is treated as a string?

I'll have to ask: why don't you use the SOAP driver?

In the REST driver, you'd have to serialize your userRecords element into a text to put into the value element. But it's entirely possible that the REST shim expects a valid JSON object within the value element...

The receiving application expects a REST request, so I don't think a SOAP driver would work. I agree that it seems like it expects a JSON object to be present in the value element.

I think I'll open an SR about this, according to the docs it should be possible.

Have you thought about using Stefaan's driver for text protocols: http://vancauwenberge.info/#txtp

With that one you should be able to do what you want, as I suspect that the Rest driver will not be able to talk XML.

Good idea. I was building the XML document using the append xml element token. But unfortunately sending it all as a text string made no difference, with or without quotes.

I remember sending XML using the REST driver, I believe I had to serialize the XML document in the output transformation.
