I am trying to use the json inspectors for the first time and I am having some issues with the path inspector. The example on developer.bigfix.com provides a link to the spec for JSONPath, which is a port of xpath for xml.
That page has several examples that all work as expected when I test them at an online tester like jsonquerytool.com. For example, executing $.store.book[*].author against the test data returns
[
"Nigel Rees",
"Evelyn Waugh",
"Herman Melville",
"J. R. R. Tolkien"
]
However, things are not going so well in QnA. Not sure if I am doing something wrong, or if the path inspector is broken. The main path query using the dollar sign works, but nothing else does.
I can use various workarounds to get the data, but I just wanted to post this to see if anyone else can verify my results.
q: path "$" of json of file "C:\Temp\BigFix\REST\Testing\store.json"
