NAME App::CSelUtils - Utilities related to Data::CSel VERSION This document describes version 0.083 of App::CSelUtils (from Perl distribution App-CSelUtils), released on 2019-07-30. DESCRIPTION This distribution contains the following utilities: * ddsel * parse-csel FUNCTIONS ddsel Usage: ddsel(%args) -> [status, msg, payload, meta] Select Perl data structure elements using CSel (CSS-selector-like) syntax. Note that this operates against Perl data structure, not Perl source code elements (see ppisel for that). File is Perl source code that defines data structure, e.g.: { summary => 'This is a hash', # this is an array inside a hash array => [ 1, 2, 3, ], }; 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: * "count" will print the number of matching nodes. * "print_method" will call on or more of the node object's methods and print the result. Example: print_method:as_string * "dump" will 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.: dump:tag.id.class which will result in a node printed like this: HTML::Element tag=p id=undef class=undef By default, if no attributes are specified, "id" is used. If the node class does not support the attribute, or if the value of the attribute is undef, then "undef" is shown. * 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. "root" will 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) parse_csel Usage: parse_csel(%args) -> [status, msg, payload, meta] Parse CSel expression. This function is not exported. Arguments ('*' denotes required arguments): * expr* => *str* 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) HOMEPAGE Please visit the project's homepage at .
