Parsing XML Documents: An Example

• We first get the number of items:

  int itemCount = Integer.parseInt(path.evaluate(
        "count(/items/item)", doc));

• For each item element, we gather the product data and construct a Product object:

  String description = path.evaluate(
        "/items/item[" + i + "]/product/description", doc);
  double price = Double.parseDouble(path.evaluate(
        "/items/item[" + i + "]/product/price", doc));
  Product pr = new Product(description, price);

• Then we construct a LineItem object, and add it to the items array list
