bookstore.xml:
<?xml version="1.0" encoding="utf-8" ?><bookstore> <book category="cooking"> <title>everyday italian</title> <author>giada de laurentiis</author> <year>2005</year> <price>30.00</price> </book> <book category="children"> <title>harry potter</title> <author>j k. rowling</author> <year>2005</year> <price>29.99</price> </book> <book category="web"> <title>learning xml</title> <author>erik t. ray</author> <year>2003</year> <price>39.95</price> </book></bookstore>
