@JSONHASXPATH[["filename",]xpath]] : Returns 1 if the specified xpath exists in the JSON file, or 0 if it doesn't.
The xpath always begins with /json.
If you do not specify a filename, @JSONHASXPATH will use the file previously opened by @JSONOPEN.
Example:
For example, with this JSON file:
{
"firstlevel": {
"one": "value",
"two": ["first", "second"],
"three": "value three"
}
}
echo %@jsonnasxpath["test.json",/json/firstlevel/one/]
