text.XPATH_JSON(xpathex) 

Operate on a JSON file and return a node-set 
or a string. Node-sets are converted to 
corresponding strings by using the standard 
XPath string conversion routine. 

For example, consider the following JSON 
file:

{ "Book":{ "creator":{ "person":{ 
"name":'<name>' } }, "title":'<title>' } }

The following expression selects all the nodes 
that are enclosed by “/Book" (a node-set) in 
the first 1000 bytes of the body of the JSON 
file and returns the corresponding string 
value, which is "<name><title>":

HTTP.REQ.BODY(1000).XPATH_
JSON(xp%/Book%) 

Parameters: 

xpathex - XPath expression

For example, consider the following JSON 
file:

{"Book":{ "creator":{ "person":{ 
"name":'<name>' } }, "title":'<title>' } } 

The following expression operates on the 
JSON file and selects all the nodes that are 
enclosed by “/Book/creator" in the first 1000 
bytes of the body, which is “creator:{ person:{ 
name:'<name>' } }.”
