Script du jour : TinyXmlReader

class TinyXmlReader
{
 
private var xmlString = "";
private var idx = 0;
 
function TinyXmlReader(aXmlString : String)
{
xmlString = aXmlString;
}
 
var tagName = "";
var isOpeningTag = false;
var content = "";
 
function Read() : boolean
{
idx = xmlString.IndexOf("<", idx);
if (idx == -1)
{
return false;
}
++idx;
 
var endOfTag = xmlString.IndexOf(">", idx);
if (endOfTag == -1)
{
return false;
}
 
tagName = xmlString.Substring(idx, endOfTag-idx);
 
idx = endOfTag;
 
// check if a closing tag
if (tagName.StartsWith("/"))
{
isOpeningTag = false;
tagName = tagName.Remove(0, 1); // remove the slash
}
else
{
isOpeningTag = true;
}
 
// if an opening tag, get the content
if (isOpeningTag)
{
var startOfCloseTag = xmlString.IndexOf("<", idx);
content = xmlString.Substring(idx+1, startOfCloseTag-idx-1);
content = content.Trim();
}
 
return true;
}
 
// returns false when the endingTag is encountered
function Read(endingTag : String) : boolean
{
var retVal = Read();
if (tagName == endingTag && !isOpeningTag)
{
retVal = false;
}
return retVal;
}
 
}
</javascript>
 
==Usage==
Here I provide example code on how to use the TinyXmlReader.
<javascript>
private var text : String;
var skin : GUISkin;
 
function OnGUI()
{
GUILayout.Label(text, skin.label);
}
 
function Start()
{
var xmlText = System.IO.File.ReadAllText(Application.dataPath + "/Rifleman.xml");
var reader = TinyXmlReader(xmlText);
while (reader.Read())
{
if (reader.isOpeningTag)
{
text += (reader.tagName + " \"" + reader.content + "\"\n");
}
if (reader.tagName == "Skills" && reader.isOpeningTag)
{
while(reader.Read("Skills")) // read as long as not encountering the closing tag for Skills
{
 
if (reader.isOpeningTag)
{
text += ("Skill: " + reader.tagName + " \"" + reader.content + "\"\n");
}
}
}
}
}
