jsonsel(%args) -> [status, msg, payload, meta]
Select JSON elements using CSel (CSS-selector-like) syntax.
This function is not exported.
Arguments ('*' denotes required arguments):
expr => str
file => str (default: "-")
node_actions => array[str] (default: ["print_as_string"])
Specify action(s) to perform on matching nodes.
Each action can be one of the following:
countwill print the number of matching nodes.
print_methodwill call on or more of the node object's methods and print the result. Example:
dumpwill show a indented text representation of the node and its descendants. Each line will print information about a single node: its class, followed by the value of one or more attributes. You can specify which attributes to use in a dot-separated syntax, e.g.:
which will result in a node printed like this:
HTML::Element tag=p id=undef class=undef
By default, if no attributes are specified,
idis used. If the node class does not support the attribute, or if the value of the attribute is undef, then
select_action => str (default: "csel")
Specify how we should select nodes.
The default is
csel, which will select nodes from the tree using the CSel expression. Note that the root node itself is not included. For more details on CSel expression, refer to Data::CSel.
rootwill return a single node which is the root node.
Returns an enveloped result (an array).
First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
Return value: (any)
