Searching a specific attribute value in an array

[NB2909]

Hi!

This is my first question here so please bear with me!
I only have a very basic understanding of JSLT and also not looking to very deep dive into it. I did not find anything that I could try myself in the basic tutorial nor the functions.

I am trying to determine the value of my attribute based on if a specific value is present in one of the array values.

Example: I am looking if the "test1234" attribute has the specific value xyz. If one of them has this value, the outcome should show a true. If not, it will be a false
{
"attribute1": "This is a test",
"array": [
{
"test1234": "xyz"
},
{
"test1234": "abc"
},
{
"test1234": "cde"
}
]
}

Expected outcome:

{
"attribute1": "This is a test",
"attribute2": true // or false if no xyz is found. Or could also be a string based on the transformation, I do not mind about that
}

Example 2 with xyz not being present:
{
"attribute1": "This is a test",
"array": [
{
"test1234": "abc"
},
{
"test1234": "cde"
}
]
}

{
"attribute1": "This is a test",
"attribute2": false
}

Very much appreciate your help!

Thanks,
Nico

Here's a solution.

Input

{ "attribute1": "This is a test", "array": [ { "test1234": "abc" }, { "test1234": "cde" }, { "test1234": "xyz" } ] }

With this transformation:

{ "attribute1": .attribute1, "attribute2": contains ("xyz", [ for (.array) .test1234 ]) } 

The result is:

{ "attribute1" : "This is a test", "attribute2" : true }

Awesome! Thanks a lot for the quick reply! I did not think about switching the contain and for function in my tries.
