Hi

I have imported a flow and one of the nodes is unknown - json2xml. I cannot find it on the web so I guess it has been superseded. Can any one suggest a suitable replacement?

Regards

Ian

If you look in the function node list you'll find a node called "JSON" and a node called "XML"  these convert to and from 
a javascript object.  

So assuming your JSON is in msg.payload, Try doing 

 - JSON - XML -

Should really update my flows on the floes site.

Suggestion: site checks flows and highlights if a flow uses deprecated nodes so people know to avoid or be prepared to update them.

Hi

yes the xml node is two way - so should just need that... if it sees json it tries to make it into xml and if it sees a string it assumes it's xml and tries to make it into json... - so you should only need the one node.

(If you then pass it through the json node - it'll then take the json and make it into a stringified version of the json... which is fine if you are then sending out over the network etc...  but not much use for manipulating, parsing etc)

re Suggestion - yes... in fact we did just add that for the very recently moved out nodes... - but indeed we should add the very old ones into that check...

I am trying to revive the flow http://flows.nodered.org/flow/637b5f6128a8d423503f which references the defunct json2xml node and trying to replace it with the xml node as recommended by @DaveCJ

while 

var messageObj = {"Response": { "Say":  "Welcome to Node-Red."}};    

results in valid TwiML

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><Response><Say>Welcome to Node-Red.</Say></Response>

something more complicated adds extraneous characters for array elements like <0> <0/> etc that twilio barfs on

In the end I just removed the xml node altogether and just formatted the TwiML as a literal string to send back as the response
Hope this helps someone else who needs to mess with TwilioIVR

If anyone has a nicer TwiML flow, please publish your flow
