This function destroys a XML node from the XML node tree.

Syntax

bool dgsSVGDestroyNode ( xmlnode theXMLNode )

Required Arguments

  • theXMLNode: The xml node you want to destroy.

Returns

Returns true if the xml node was successfully destroyed, false otherwise.

Example

Click to collapse [-]
Client
loadstring(exports.dgs:dgsImportFunction())() -- load dgs functions using loadstring.

local svg = dgsCreateSVG(500,500) -- Create the SVG . 
local svgDoc = dgsSVGGetDocument(svg) -- Get the SVG Document so you can modify it .
local rect = dgsSVGCreateNode(svgDoc,"rect",50,50) -- Create SVG node with rect shape. 
dgsSVGNodeSetAttributes(rect,{ -- Change the rect shape attributes value .
 	["stroke"] = {255,255,0},
	["stroke-width"] = "5px",
 	["fill"] = "rgb(255,0,0)",
})
local theImage = dgsCreateImage(200,200,500,500,svg,false) -- Render the SVG by dgsCreateImage

dgsSVGDestroyNode(rect) -- Destroy rect node
local circle = dgsSVGCreateNode(svgDoc,"circle",50,50) -- add circle node. 
dgsSVGNodeSetAttributes(circle,{ -- Change the node attributes value .
        ['r'] = "40",
 	["stroke"] = {255,255,0},
	["stroke-width"] = "5px",
 	["fill"] = "rgb(255,0,0)",
})
