Hi,
I'm trying to parse an XML string value from the "text" field under "post" entity in Dynamics 365.
Here's is the sample value of the field:
"<?xml version="1.0" encoding="utf-16"?><pi id="Account.Create.Post" icon="0" ya="1"><ps><p type="1" otc="8" id="ff87e0f2-813f-eb11-bf68-000d3a3abbc3">David So</p></ps></pi>"
I'm assigning that value to a Compose step then uses another Compose (Compose 2) step to parse it using xpath

I am trying to get the string value, David So, of the p node but I'm getting this error:

is there anything wrong with the syntax of the expression I'm using?
I'd appreciate any feedback on this. thank you.
