jsoup解析html主题,使用jsoup解析html页面内容案例

public String getFaGuiKuTitles(String type, intpage) {

String href= "http://info.qd-n-tax.gov.cn/NewFaGuiKu/"+type+"/";

String baseUrl= href + "index";int no = 0;

String msg= "";if(page>0){

baseUrl= baseUrl + "_"+page;

}

baseUrl+= ".htm";int totalPage = 0;

List list = new ArrayList();try{

URL url= newURL(baseUrl);

org.jsoup.nodes.Document doc= Jsoup.parse(url, 10000);

org.jsoup.nodes.Element table= doc.select("table").get(0);

org.jsoup.nodes.Element tbody= table.select("tbody").get(0);

org.jsoup.select.Elements rows= tbody.select("tr");int len =rows.size();for (int i = 0; i < len; i++) {

org.jsoup.select.Elements cols= rows.get(i).select("td");

FaGui fg= newFaGui();

fg.setTitle(cols.get(0).text());

fg.setDate(cols.get(1).text());if(cols.size()>2){

fg.setFwzh(cols.get(2).text());

}

org.jsoup.nodes.Element a= cols.get(0).select("a").get(0);

fg.setHref(a.attr("href").replaceFirst("./", href));

list.add(fg);

}//翻页信息

String pager = doc.getElementsByClass("pager").get(0).html();int start = pager.indexOf("(")+1;int end = pager.indexOf(",");

pager= pager.substring(start, end);//截取页面中的总页数

if(pager.matches("\\d+")){

totalPage=Integer.parseInt(pager);

}

no= 1;

msg= "SUCCESS";
