XML

[Drakath]

Is it possible to xmlDestroyNode if I know the tagName and its value but no index?

[JR10]

How about xmlFindChild?

That requires to define index.

[Vector]

  
  
-- iterate over all the xml nodes and find those whose value and  tag name matches...  
local children = xmlNodeGetChildren(root); 
  
for _, child in ipairs(children) do  
     if (xmlNodeGetName(child) == tagName) and (xmlNodeGetValue(child) == someValue) then  
        xmlDestroyNode(child); 
     end;   
end;

That requires to define index.

index: This is the 0-based index of the node you wish to find. For example, to find the 5th subnode with a particular name, you would use 4 as the index value. To find the first occurence, use 0.

This is a different index than what you mean.

Well it only returns the first line. While for the Vector's code, I tried this:

local xmlFile = xmlLoadFile("blocks.xml") 
local children = xmlNodeGetChildren(xmlFile) 
outputChatBox(playername) 
for _, child in ipairs(children) do 
outputChatBox(xmlNodeGetValue(child)) 
if (xmlNodeGetValue(child) == playername) then 
xmlDestroyNode(child) 
outputChatBox("deleted") 

playername outputted correctly but xmlNodeGetValue(child) outputted nil. Why?

Post the xml file.

<blocked> 
    <blocked blocked="Drakath"></blocked> 
    <blocked blocked="player"></blocked> 
    <blocked blocked="lol"></blocked> 
    <blocked blocked="user"></blocked> 
</blocked>

xmlNodeGetValue will return 'Drakath' if:

<blocked>Drakath</blocked> 

Use xmlNodeGetAttribute(child, 'blocked')

[Drakath]

It worked but seems like xmlDestroyNode(child) doesn't do anything. It didn't delete anything from blocks.xml

[JR10]

You need xmlSaveFile and xmlUnloadFile at the end of the script.

Oh, I forgot. Thanks
