Re: getAttribute()

[Alain DESEINE <alain@xxxxxxxxxxx>]

Here is a complete stylesheet i wrote as an example of XML/XSL
technologies for my web site (http://www.cabinfo.com  i'm sorry, but the
web site is in french, i haven't time to translate it now !)

In this stylesheet i extract many attribut from the elements
<INGREDIENT> and <RECETTE> there is also 
a script which can be interessant as it iterate through all the
childrens elements of the RECETTE element.

<xsl>

<define-script><![CDATA[
	function GetCalorie(thisRecette)
	{
		// Cette fonction renvoie le nombre de calorie par parts
		// This function return the total amount of "calories" for one portion 
		// Notice that the script is not optimized, cause it's just an example
		// It **need** to be optimized !!!
		var CalorieParPart, aCal, ingredients, numIngredients, Ingredient;
		var TotalCalorie;

		TotalCalorie = 0;

		ingredients = thisRecette.children.item("INGREDIENTS", 0);
		numIngredients = ingredients.children.item("INGREDIENT").length;
		for (i = 0; i < numIngredients; i++)
		{
			Ingredient = ingredients.children.item("INGREDIENT", i);
			aCal = Ingredient.getAttribute("CALORIE");
			TotalCalorie = TotalCalorie + parseInt(aCal, 10);
		}

		CalorieParPart = TotalCalorie /
parseInt(thisRecette.getAttribute("NOMBREPARTS"), 10);

		return CalorieParPart;

	}
	]]></define-script>
