Converting XML data issues

[Anonymous]

I have a flow set up that receives XML data from an API. If it returns only one item, it comes as an object, if more than one item, it's an array. My mind is going blank for the right expression. How would I add a condition that says 'if it's an object do something' otherwise 'if it's an array, loop through them'.

Hi @Anonymous,

There is no action or function that could determine an item is an array or object.

As a workaround, you could use the length() function to determine it, if the item is an object, it will fail, and you can make a branch to make the Flow could run when the length() function failed; if the item is an array, it will return a number, then Flow will go to the right side of array.

Thank you. I thought I had tried that but I realized I hadn't added it into its own variable if it failed.

Hi @Anonymous,

Yes, the short of workaround is every time the flow will report an error no matter it is an object or array.

I just thought of another way is convert the data into a string, then use contains() function to check it whether contains "[" and "]", because an array must contain "[" and "]", for example:

contains(string(outputs('Compose')),'[')
