jsoup之解析doc

1、生成document的方法

        Document course = Jsoup.connect("http://202.114.224.81:7777/pls/wwwbks/bkscjcx.curscopre").cookies(cookies)
                .timeout(3000).post();

或者

subString是html代码

        Document course = Jsoup.parse(subString);

2、

如果html有如下代码

<td width="112" height="20" class=td_biaogexian><p align="center">形势与政策（3）</p></td>

得到关键字

        Document course = Jsoup.connect("http://202.114.224.81:7777/pls/wwwbks/bkscjcx.curscopre").cookies(cookies)
                .timeout(3000).post();
        Iterator<Element> elements = course.getElementsByAttributeValue("class", "td_biaogexian").iterator();
         for (Iterator iter = elements; iter.hasNext();) {
            Element element = (Element)iter.next();
            System.out.println( element.attributes());
            System.out.println(element.text());
         }

输出attributes和text

width="112" height="20" class="td_biaogexian"
B1380030
width="112" height="20" class="td_biaogexian"
环境科学与公民环境素质
