//HtmlPage extends visitor,Apply the given visitor to the current
//page.
parser.visitAllNodesWith(page);
}catch (ParserException e1) {
e1= null;
}
//所有的节点
NodeListnodelist = page.getBody();
//建立一个节点filter用于过滤节点
NodeFilterfilter = new TagNameFilter("A");
//得到所有过滤后，想要的节点
nodelist= nodelist.extractAllNodesThatMatch(filter, true);
for(int i = 0; i < nodelist.size(); i++) {
LinkTaglink = (LinkTag) nodelist.elementAt(i);
//链接地址
System.out.println(link.getAttribute("href")+ "\n");
//链接名称
System.out.println(link.getStringText());
}
}
}
结果如下：
