jsoup教程：URL解析HTML获取书籍信息

列如
public static List<Book> getFirstBookInfo(String url) {
List<Book> list =null;
Book book = new Book();
try {
Document doc = Jsoup.connect(url).get();//http://www1.17k.com/book/182745.html
Elements select = doc.select("html>head>meta");
Iterator<Element> iterator = select.iterator();
Elements select2 = doc.select("div.bookTit>h1>a[href]");
for (Element link : select2) {
String href = "http://www1.17k.com"+link.attr("href");
book.setSrc_url(href);
System.out.println("href:"+href);
}
int i = 0;
while (iterator.hasNext()) {
Element next = iterator.next();
String string = next.toString();
String[] split = string.split("=");
StringBuilder sBuilder = new StringBuilder(split[split.length-1]);
sBuilder.delete(0, 1);
if (i==6) {//获取名字
String b_name = ""+sBuilder.delete(sBuilder.indexOf("\""), sBuilder.length());
book.setName(b_name);
}else if(i==8) {//获取图片链接
String image = ""+sBuilder.delete(sBuilder.indexOf("\""), sBuilder.length());
book.setCover_url(image);
}else if(i==9){//获取内容 介绍
String summary = ""+sBuilder.delete(sBuilder.indexOf("\""), sBuilder.length());
book.setSummary(summary);
