Hello,

A request has json payload. In the json there is a field which has xml data encoded with base64. What is the good way to validate the xml data with the xml schema after base64 decoding in Multiple Protocol Gateway .

example payload:

{

"Mainpaylod": {

"field1": "field1-value",

"field2" : "field2-value",

"SecPayload": {

"xmlbase64": "base64xmlmessage"

}

}

}

Thanks

Hi,

maybe a trivial answer but I would use the schema validate action. Perhaps extract and decode the XML with GatewayScript and then validate action.

Alternatively call XSLT with transform.XSLT() and in stylesheet use "dp:schema-validate()":

Hello,

Thanks for your reply. I will try with GatewayScript.

Here is a non-trivial example showing how to execute dynamic XSLT from GatewayScript. Replace dp:xquery-transform() with dp:schema-validate():
