New To XML

[simreality]

I've been looking through TinyXML for a few days but can't figure it out. I have already created a small XML file but cannot figure out the correct way to use it. Here's my XML:
<level number="1" width="50" height="20">
    <block x="0" y="3" z="0" w="50" h="1"/>
    <block x="7" y="2" z="0" w="4" h="1"/>
    <block x="10" y="3" z="0" w="4" h="1"/>
    <block x="29" y="3" z="0" w="50" h="1"/>
    <block x="33" y="7" z="0" w="50" h="1"/>
    <block x="31" y="0" z="0" w="50" h="1"/>
    <block x="22" y="0" z="0" w="50" h="1"/>
    <block x="42" y="0" z="0" w="50" h="1"/>
    <block x="50" y="0" z="0" w="50" h="20"/>
    <block x="0" y="0" z="0" w="50" h="20"/>
    <player x="2" y="2" z="0" w="1" h="2"/>
</level>

Quite simple enough. How can I easily access those numbers? All I need to do is assaign those values to a bunch of variables in the code? I also need to have a function that counts the number of <block> lines so as to allocate the proper number of blocks in my program.
Any help is appreciated.

Here's a code that read the file, count the <block> elements and allocate the width and height
There's no error checking though

   TiXmlDocument simpledoc;
   TiXmlElement * level, * block;
   int height, nb_block, width;

   simpledoc . LoadFile ("simple.xml");
   level = simpledoc . RootElement ();
   level -> Attribute ("width", & width);
   level -> Attribute ("height", & height);
   nb_block = 0;
   block = level -> FirstChildElement ("block");
   while (block)
   {
      nb_block++;
      block = block -> NextSiblingElement ("block");
   }

How do I assign those values to variables? Is that what's happening on the level->Attribute("width",&width) line?

Yes, indeed,

Take a look at the TiXmlElement documentation :

http://www.grinninglizard.com/tinyxmldocs/classTiXmlElement.html

It explains the 3 different forms you can use to retrieve the attribute values.
You can also use TiXmlElement::QueryIntAttribute
