- node: The node of which you wish to edit an attribute.
- name: The name of the attribute.

Example
Click to collapse [-]
ServerIn a gamemode, we want a command to change the marker color in the configuration file and remove a deprecated attribute.
config.xml:
<config>
<markers color="255,100,0" foo="deprecated" />
</config>
Lua code:
function changeConfigMarkerColor(thePlayer, command, r, g, b)
local config = xmlLoadFile("config.xml")
local markernode = xmlFindChild(config, "markers", 0)
xmlNodeSetAttribute(markernode, "color", r .. "," .. g .. "," .. b)
xmlNodeSetAttribute(markernode, "foo", nil) -- remove 'foo' attribute
xmlSaveFile(config)
xmlUnloadFile(config)
end
addCommandHandler("markercolor", changeConfigMarkerColor)
