PHP - Theory 3 - Demo XML

<recipe version="1.0" encoding="ISO-8859-1">
    Here's the root element. It's not called html, it's called
      recipe, since this is the XML for a recipe. Notice it has some extra
        attributes in it, which you've never seen on an html element in HTML.
      <name>Head First Lounge Iced Tea</name>
        Wow, look at these tags. The h1 and p  are all gone, and instead we've got
        recipe, name, description, ingredients,
        preparation, and so on.
        Just by looking at the element names you can tell this is a recipe.
      <description>A brisk iced tea with a bit of a kick. We
           serve this all day long.
      </description>
      <ingredients>
        <ingredient measurement="6 cups">water</ingredient>
        <ingredient measurement="2 bags">black tea</ingredient>
        <ingredient measurement="2 bags">earl grey tea</ingredient>
        <ingredient measurement="6 cups">ice</ingredient>
      </ingredients>
      <preparation>
        <time duration="10 minutes" /> This empty element
 looks a little strange. We'll come back to that in a bit.
        <step>Boil one cup of water in a pan, remove pan, and
            add tea. Let steep for five minutes.</step>
        <step>Add ice to a pitcher, then add tea,
then 5 cups cold water.</step>
        <step>Mix well and serve. Give tea a
                  quick shake in a shaker for an
                  extra touch.</step> Other
than the element names, the way the elements look and are used is just like HTML (opening
 tags, closing tags, and so on).
