Question

我已经可以在网站中导航并获得我想要的所有链接。但我的主要目标是获得酒店的评论。我正在使用的网站是http://www.booking.com/hotel/pt/park-italia-flat.pt-pt.html?label=gen173nr-17CAEoggJCAlhYSDNiBW5vcmVmaLsBiAEBmAEvuAEEyAEE2AEB6AEB-AEL;sid=637e7af0c3009aa9ea132a960e2d2d40;dcid=4;ucfs=1;room1=A,A;srfid=b8260a1c264a3873291a9061733a43536a4d35c2X979#tab-reviews 我可以在哪里使用jsoup没问题，但现在我不知道如何获取文本。我已经尝试了getElementsByTag和getText以及其他解决方案。这可以用jsoup完成，或者我需要另一个库。我正在尝试这种方式来获取文本。但出现的文字不是我想要的。

        Document doc ;
        try {
            doc = Jsoup.connect(pair.getValue().toString() + "#tab-reviews").get();
            Elements scriptElements = doc.getElementsMatchingText("span");
            for (Element link : scriptElements ) {
                System.out.printf(" Text: <%s> \n", link.text());
            }

        } catch (IOException ex) {
            Logger.getLogger(GetComentsThread.class.getName()).log(Level.SEVERE, null, ex);
        }

为了获取我使用类似内容的网址。

Pattern pattern = Pattern.compile("src=destinationfinder");
            Document doc = Jsoup.connect(url).get();
            Elements links = doc.select("a[href]");
            for (Element link : links) {
                Matcher matcher = pattern.matcher(link.attr("abs:href"));
                if (matcher.find()) {
                    dest = link.attr("abs:href");
                    break;
                }
            }

现在我可以得到一些评论，但只有积极的不知道为什么

doc = Jsoup.connect(pair.getValue().toString() + "#tab-reviews").get();
                    //doc = Jsoup.connect("http://www.booking.com/hotel/pt/pestanaportohotel.pt-pt.html?label=gen173nr-17CAEoggJCAlhYSDNiBW5vcmVmaLsBiAEBmAEvuAEEyAEE2AEB6AEB-AEL;sid=cff2dddd95e71c0768847a554584c888;dcid=4;dist=0;group_adults=2;room1=A%2CA;sb_price_type=total;srfid=798bd6b01ea1dba53ee6b6b945dda1f623859730X2;type=total;ucfs=1&#tab-reviews").get();
                    String teste="p.trackit";


                    Elements scriptElements = doc.select(teste);
                    for (Element link : scriptElements) {

                        //System.out.printf(" Text: <%s> ...%s\n", link.text(),link.attr("class=\"review_pos\""));
                        System.out.printf(" Text: <> ...%s\n",link.text());

                    }

使用对another url的AJAX请求加载评论。

在那里，您可以获得所需的所有信息。

看起来你只需要使用jsoup来获取内容类=＆＃34; review_pos＆＃34;和class =＆＃34; review_neg＆＃34;
