This function is used to edit an attribute of a node in a configuration file.
Syntax
bool xmlNodeSetAttribute ( xmlnode node, string name, string/float value )
OOP Syntax Help! I don't understand this!
- Method: xmlnode:setAttribute(...)
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
Click to collapse [-]
ServerIn 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(thePlayer, command, r, g, b)
local markernode = xmlFindChild(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.
