get_values: Get values from an imported SVG file

In m-jahn/fluctuator: An Interface to Import and Modify SVG (XML) Graphic Files

Get values from an imported SVG file

Description

SVG files and the imported representation of class 'XMLsvg' are hierarchically organized in node sets and nodes. Each node is a graphical object such as a path, rectangle, or text. The values of these nodes can be queried using this function. A typical application for this function is to query the content of a text field. If you want to retrieve the (style) _attributes_ of a text field, use get_attributes() instead.

Usage

get_values(xml, node = NULL, node_attr = "label")

Arguments

xml	(XMLsvg) XMLsvg object obtained from read_svg()
node	(character) node(s) to be modified. Node names are searched using the 'node_attr' field
node_attr	(character) name of the attribute by which target nodes are filtered (default: "label")

Value

Returns a named list with values for the queried nodes (or NULL if no value exists)
