<bookstore><book category="cooking"><title lang="en">Everyday Italian</title><author>Giada De Laurentiis</author><year>2005</year><price>30.00</price></book><book category="children"><title lang="en">Harry Potter</title><author>J.K.

Ray</author><year>2003</year><price>39.95</price></book>
</bookstore>?doc.Load("books.xml");
?XmlNodeList nodes = doc.SelectNodes("//book[contains(title, 'Harry')]");
nodes就是模糊查找結果
