java - 如何使用Jsoup获取html数据的特定子元素

Question

所以我尝试使用 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">
        $509
    </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">
        $1,046
    </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

这是我迄今为止尝试过的:

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">
    $509
</div>
<div class="price-point price-point-revised use-roundtrippricing">
    $1,046
</div>
.....

但现在我只想要这样的价格:

509
1046

我尝试使用正则表达式，在打印时仅保留数字 e.toString().replaceAll("\\D+","") ，这似乎有效，但这不是我想要的来实现它。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

$509 
$1,046

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。
