This function is used to edit an attribute of a node in a configuration file.
Syntax
bool xmlNodeSetAttribute ( xmlnode node, string name, var value )
Required Arguments
- node: The node of which you wish to edit an attribute.
- name: The name of the attribute.
- value: The value which you wish to change the attribute to.
Returns
Returns true if the attribute was set successfully, false if the node and/or attribute do not exist, or if they're faulty.
Example
In a gamemode, we want a command to change the marker color in the configuration file.
config.xml:
<config> <markers color="255,100,0" /> </config>
Lua code:
config = xmlLoadFile("config.xml") function changeConfigMarkerColor(player, command, r, g, b) local markernode = xmlFindSubNode(config, "markers", 0) xmlNodeSetAttribute(markernode, "color", r .. "," .. g .. "," .. b) end addCommandHandler("markercolor", changeConfigMarkerColor)
Note that this example only changes the in-memory XML document. If you want to save the changed document back to the hard drive, use xmlSaveFile.
