（1）从字符串解析
String html = "
Parse HTML into a doc.
";Document doc = Jsoup.parse(html);
?
（2）从URL获取解析
Document doc = Jsoup.connect("http://example.com/").get();
String title = doc.title();
Document doc = Jsoup.connect("http://example.com") .data("query", "Java").userAgent("Mozilla").cookie("auth", "token").timeout(3000).post();
?
?
（3）从文件解析
File input = new File("/tmp/input.html");
Document doc = Jsoup.parse(input, "UTF-8", "http://example.com/");
2.DOM方式遍历元素
（1）搜索元素
getElementById(String id)
getElementByTag(String tag)
getElementByClass(String className)
getElementByAttribute(String key)
siblingElements(), firstElementSibling(), lastElementSibling(), nextElementSibling(), previousElementSibling()
parent(), children(), child(int index)
（2）获取元素数据
attr(String key) ? 获取key属性
attributes() ? 获取属性
id(), className(), classNames()
text() ? 获取文本内容
html() ? 获取元素内部HTML内容
outerHtml() ? 获取包括此元素的HTML内容
data() ? 获取
