//读取文本内容
String txt = IOUtil.readDirOrFile("cssquerytest", "UTF-8");
//System.out.println(txt);
//利用Jsoup解析成document
Document doc = Jsoup.parse(txt);
//如果查找所有的超链接元素,cssQuery代码如下:<非常简洁>
Elements elements = doc.select("a");
for(Element ele:elements){
System.out.println(ele.toString());
}
System.out.println("-------------------");
//例如,我要找到超链接<a>元素..并且他的href属性的值为www.baidu.com,cssQuery代码如下:
elements = doc.select("a[href=www.baidu.com]");
for(Element ele:elements){
System.out.println(ele.toString());
}
System.out.println("-------------------");
//根据样式的名称,class中有空格时，写多个select或者将空格替换为.
//选择器选择的class有多个属性的写法
elements = doc.select("p.test.link");
for(Element ele:elements){
System.out.println(ele.toString());
}
System.out.println("-------------------");
//获得div下的<p>标签
elements = doc.select("div p");
for(Element ele:elements){
System.out.println(ele.toString());
}
System.out.println();
