如何使用Jsoup获取html数据的特定子元素

Question

所以我正在尝试使用 Jsoup 从 Html 文件中获取所有价格。简化的 Html 结构如下：

//some html

<div class="price-point-wrap use-roundtrippricing">
    <div class="price-point-wrap-top use-roundtrippricing">


    <div class="pp-from-total use-roundtrippricing">Roundtrip</div>
    </div>
    <div class="price-point price-point-revised use-roundtrippricing">
        9
    </div>

    <div class="fare-select-button-div">
        <input type="button" aria-describedby="sr_product_ECONOMY_123-745|1975-UA" value="Select" class="fare-select-button">
        <span class="visuallyhidden">fare for Economy  (lowest)</span>
    </div>

</div>

//some html

 <div class="price-point-wrap use-roundtrippricing">
    <div class="price-point-wrap-top use-roundtrippricing">


    <div class="pp-from-total use-roundtrippricing">Roundtrip</div>
    </div>
    <div class="price-point price-point-revised use-roundtrippricing">
        ,046
    </div>

    <div class="fare-select-button-div">
        <input type="button" aria-describedby="sr_product_MIN-BUSINESS-OR-FIRST_123-745|1975-UA" value="Select" class="fare-select-button">
        <span class="visuallyhidden">fare for First  (2-cabin, lowest)</span>
    </div>

    <div class="pp-remaining-seats">5 tickets left at this price</div>
</div>

//some html

这是我目前尝试过的方法：

File input = new File("Flights.html");
Document document = Jsoup.parse(input, "UTF-8", "");
Elements prices = document.getElementsByClass("price-point");
for(Element e: prices){
    System.out.println(e.toString());
}

这给了我以下结果：

<div class="price-point price-point-revised use-roundtrippricing">
    9
</div>
<div class="price-point price-point-revised use-roundtrippricing">
    ,046
</div>
.....

但现在我只想要这样的价格：

509
1046

我通过在打印时仅保留数字 e.toString().replaceAll("\D+","") 来尝试正则表达式，这似乎可行，但这不是我想要实现的方式。如何使用 Jsoup 只获取数字？

Answer 1

感谢@Eritrean 的评论，我需要使用 e.text() 而不是 e.toString() 这给了我

9 
,046

我仍然需要使用像 e.replaceAll("[$,]", "") 这样的正则表达式来去掉美元符号。
