XML by Example

var i;

for(i = 0;i < products.length;i++)

if(products[i] != null)

xmlCode += products[i].toXML();

return element(“products”,””,xmlCode);

}

Notice that this approach is recursive. Product implements its toXML()

method partly by serializing the list of Price and wrapping it in a product

element.

function product_toXML()

{

var result = element(“name”,””,escapeXML(this.name)),

i;

for(i = 0;i < this.prices.length;i++)

result += this.prices[i].toXML();

return element(“product”,””,result);

}

function price_toXML()

{

return element(“price”,

“currency=\”” + this.currency + “\””,

escapeXML(this.amount));

}

XML is a convenient format because elements can nest in a way that ...
