Come on! You have a solution to get the fields on screen, and one to extract the field names without using a!keys(). Please combine the two!

Hi Stefan,

In the first post we had to use a!keys() but with our Appian version it is not allowed. We use 21.1

Sure. Check my first post!

Hi Stefan,

We do not get the key-value pair with the above code. We only get the keys as output.

I had to add backslashes to escape the quotes in field 2. But this is working.

a!localVariables(
  local!jsonString: "{
""Field1"":""Test"",
""Field2"":""value is \""not editable\"" test it."",
""Field3"":""314146282515"",
""Timestamp"":""2019-06-19T11:05:23.678+0000"",
""Field4"":""XYZ"",
""Reason"":""XYZ"",
""Time"":""2022-02-19T05:09:26.046+0000"",
""Field5"":""ABC"",
""Field6"":""yui"",
""Value"":""OK"",
""Action"":"""",
""Field7"":""[abcged]"",
""Field8"":"""",
""Field9"":{
""Value1"":""test"",
""Value2"":""Test"",
""Value3"":""Test"",
""Value4"":""Test"",
""Value5"":null,
""Value6"":[
{
""value"":""C:"",
""name"":""instance""
},
{
""value"":""ty"",
""name"":""object""
},
{
""value"":""er46"",

}
],
""Field9"":300,
""Periods"":1,
""Operator"":""LessThanOrEqualTo"",
""Field10"":25.0,

}
}",
  local!appianType: a!fromJson(local!jsonString),
  a!flatten(apply(xpathsnippet(_, "name(*)"), xpathsnippet(toxml(local!appianType), "/*/*")))
)

Hi Stefan,

When we do toxml(<OUR_DATA>) it comes in below format,

<a:Variant xmlns:a="http://www.appian.com/ae/types/2009" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xsd:string">{"Field1":"Test","Field2":"value is "not editable" test it.","Field3":"314146282515","Timestamp":"2019-06-19T11:05:23.678+0000","Field4":"XYZ","Reason":"XYZ","Time":"2022-02-19T05:09:26.046+0000","Field5":"ABC","Field6":"yui","Value":"OK","Action":"","Field7":"[abcged]","Field8":"","Field9":{"Value1":"test","Value2":"Test","Value3":"Test","Value4":"Test","Value5":null,"Value6":[{"value":"C:","name":"instance"},{"value":"ty","name":"object"},{"value":"er46","name":"test"}],"Field9":300,"Periods":1,"Operator":"LessThanOrEqualTo","Field10":25.0,"Feild11":"ignore","Field12":""}}</a:Variant>

And when we apply the code that you have given replacing the ri!cdt with our value it gives us {}

The snippet returns a list of the field names, just like a!keys() does. I highlighted the spot which you have to modify to refer to your data structure.

apply(xpathsnippet(_, "name(*)"), xpathsnippet(toxml(<YOUR_DATA_STRUCTURE>), "/*/*"))

RE: Show a JSON text in an interface

sravanthik0001 — Tue, 29 Mar 2022 08:09:44 GMT

Can you please let us know what values should be kept in place of name(*) and what is ri!cdt? And should we call this code inside a rich text editor or paragraph ( as our data comes in bulk we cannot use text editor only)

Hi Harshit,

We can parse the data but how can we show it in interface? We use Appian 21.1 version

apply(xpathsnippet(_, "name(*)"), xpathsnippet(toxml(ri!cdt), "/*/*")),

sravanthik0001 — Tue, 29 Mar 2022 07:19:19 GMT

We use Appian version 21.1 where a!keys() is not supported. Any suggestion for our query posted above?

Not a full proof idea tho but you can check if the string starts and ends with a curly brace then it is a JSON else it is a text.
If that is a JSON, then you can use the fromJson() function to convert JSON to a dictionary.

Thank you. One more question will it work for a normal text field also?
is there any way how we can do a check whether the data is in text format or json?

You might have to add recursion to also display nested structures.
