Question

鉴于此HTML：

＆＃13;

<div id="cat-product-list" alt1="356623" class="product-list list_all_items_price price_new"><span id="wholesale_11_member_price" class="index-price special_price final_price" price="US$5.25"><strong class="final_price_strong">US$5.25</strong><b class="show_vip">(vip)</b></span><span id="wholesale_12_member_price" class="index-price special_price final_price" price="US$4.90" style="display: none"><strong class="final_price_strong">US$4.90</strong><b class="show_vip">(vip)</b></span><span id="wholesale_13_member_price" class="index-price special_price final_price" price="US$4.55" style="display: none"><strong class="final_price_strong">US$4.55</strong><b class="show_vip">(vip)</b></span><span id="wholesale_14_member_price" class="index-price special_price final_price" price="US$4.20" style="display: none"><strong class="final_price_strong">US$4.20</strong><b class="show_vip">(vip)</b></span><span id="shop_price_member_price_on" class="index-price shop_price" price="US$7.00"><strike>US$7.00</strike></span></div>

＆＃13;

我正在尝试选择div中的第一个span，然后获得强大的值。到目前为止，我成功地抓住了其他东西，但是为此，我无法完成它：

Document d = Jsoup.connect("http://www.emmacloth.com/Clothing-vc-7061.html?icn=clothing&ici=ec_navbar05").timeout(6000).get();
    Elements elements =  d.select("div#productsContent1_goods.products_category");
    for (Element element: elements.select("div.box-product-list.list_all_items")){
        System.out.println("start");
        String productImage = element.select("div.goods_aImg a img").attr("src");
        String productname = element.select("div.goods_mz a").attr("title");
        String productUrl = "http://www.emmacloth.com" + element.select("div.goods_mz a").attr("href");
 //         String productPrice = element.select("div.product-
list.list_all_items_price.price_new >span.index-price.special_price.final_price").toString();
        Elements priceElements = element.select(
                "div.product-list.list_all_items_price.price_new > span.index-price.special_price.final_price"
        );

        for (Element priceElement : priceElements) {
            System.out.println(priceElement.attr("price"));
        }
//          System.out.println(productPrice);



    }
}

在这个div中，您正在寻找具有以下类别的span：index-price special_price final_price并且从那里（我想想）您要提取price。

鉴于您的问题中提供的html，以下代码......

String html = "<div id=\"cat-product-list\" alt1=\"356623\" class=\"product-list list_all_items_price price_new\">" +
    "<span id=\"wholesale_11_member_price\" class=\"index-price special_price final_price\" price=\"US$5.25\">" +
    "<strong class=\"final_price_strong\">US$5.25</strong>" +
    "<b class=\"show_vip\">(vip)</b>" +
    "</span>" +
    "<span id=\"wholesale_12_member_price\" class=\"index-price special_price final_price\" price=\"US$4.90\" style=\"display: none\">" +
    "<strong class=\"final_price_strong\">US$4.90</strong>" +
    "<b class=\"show_vip\">(vip)</b>" +
    "</span>" +
    "<span id=\"wholesale_13_member_price\" class=\"index-price special_price final_price\" price=\"US$4.55\" style=\"display: none\">" +
    "<strong class=\"final_price_strong\">US$4.55</strong>" +
    "<b class=\"show_vip\">(vip)</b>" +
    "</span>" +
    "<span id=\"wholesale_14_member_price\" class=\"index-price special_price final_price\" price=\"US$4.20\" style=\"display: none\">" +
    "<strong class=\"final_price_strong\">US$4.20</strong>" +
    "<b class=\"show_vip\">(vip)</b>" +
    "</span>" +
    "<span id=\"shop_price_member_price_on\" class=\"index-price shop_price\" price=\"US$7.00\"><strike>US$7.00</strike></span>" +
    "</div>";

Document doc = Jsoup.parse(html);

// this selector selects the div(s) having classes: "product-list list_all_items_price price_new"
// and within that div, it selects the span(s) having the classes: "index-price special_price final_price"
Elements priceElements = doc.select(
        "div.product-list.list_all_items_price.price_new > span.index-price.special_price.final_price"
);

for (Element priceElement : priceElements) {
    System.out.println(priceElement.attr("price"));
}

...将打印出产品价格：

US$5.25
US$4.90
US$4.55
US$4.20

或某些原因，它不适用于整个网站，你能查看我修改过的问题

以下代码......

Document d = Jsoup.connect("http://www.emmacloth.com/Clothing-vc-7061.html?icn=clothing&ici=ec_navbar05").timeout(6000).get(); for (Element element : d.select("div#productsContent1_goods.products_category > div.box-product-list.list_all_items")) { System.out.println("start"); String productImage = element.select("div.goods_aImg > a > img").attr("src"); String productname = element.select("div.goods_mz > a").attr("title"); String productUrl = "http://www.emmacloth.com" + element.select("div.goods_mz > a").attr("href"); System.out.println(productImage); System.out.println(productname); System.out.println(productUrl); }

..将打印：

到目前为止，这么好。但是price呢？如果您查看此网页的来源，您会看到price元素是由该页面上的category_price JS函数提供的动态内容。因此，该元素不存在静态，因此JSoup无法读取。要阅读动态内容，您必须使用Selenium等网络驱动程序。

使用Jsoup解析div内的span
