In my previous blog post I talked about how to read from an XML Webervice and use xpath to query the XML on the expressions side of things. You can read the XML article here (https://the.agilesql.club/2021/02/adf-xml-objects-and-xpath-in-the-expression-language/). Now, what if we don't have XML but have JSON? Well well indeed, what if there was a way to query JSON documents using a query, imagine if you will a JSONQuery where you can pass a similar query to an xpath query to retrieve specific values from the JSON document.
