HtmlCleanner结合xpath用法

        HtmlCleaner cleaner = new HtmlCleaner();   

        TagNode node = cleaner.clean(new URL("http://finance.sina.com.cn/money/nmetal/20091209/10157077895.shtml"));   
        //按tag取.   
        Object[] ns = node.getElementsByName("title", true);    //标题   

        if(ns.length > 0) {   
            System.out.println("title="+((TagNode)ns[0]).getText());   
        }   
        // /html/body/div[2]/div[4]/div/div/div/div[2]/p
        ns = node.evaluateXPath("//div[@class=\"blkContainerSblkCon\"]/p"); //选取class为指定blkContainerSblkCon的div下面的所有p标签
        for (int i = 0; i < ns.length; i++) {
        	 String in = cleaner.getInnerHtml((TagNode)ns[i]);
             System.out.println("
"+in + "
");
		}
        String in = cleaner.getInnerHtml((TagNode)ns[0]);
        System.out.println(in);

        System.out.println(((TagNode)ns[0]).getText()); 

        HtmlCleaner cleaner = new HtmlCleaner();   
        String url = "http://finance.sina.com.cn/nmetal/hjfx.html";
        URL _url = new URL(url);

            System.out.println("title="+((TagNode)ns[0]).getText());   
        }  


        ns = node.evaluateXPath("//*[@class='Frame-Row3-01-C']/table[2]/tbody/tr/td/a"); //选取class为指定blkContainerSblkCon的div下面的所有p
        for (int i = 0; i < ns.length; i++) {

//        System.out.println(((TagNode)ns[0]).getText());

//        System.out.println("ul/li:");   
//        //按xpath取   
//        ns = node.evaluateXPath("//div[@class='d_1']//li");   
//        for(Object on : ns) {
