有沒有辦法檢查一個表是否有使用jsoup的某一行?檢查表數據 - Jsoup
我得到了java.lang.IndexOutOfBoundsException: Invalid location 1, size is 1
例外,我對獲得信息出表的代碼是:
docTide = Jsoup.connect("http://www.mhpa.co.uk/search-tide-times/").timeout(600000).get();
Elements tideTimeOdd = docTide.select("div.tide_row.odd div:eq(0)");
Elements tideTimeEven = docTide.select("div.tide_row.even div:eq(0)");
Elements tideHightOdd = docTide.select("div.tide_row.odd div:eq(2)");
Elements tideHightEven = docTide.select("div.tide_row.even div:eq(2)");
Element firstTideTime = tideTimeOdd.first();
Element secondTideTime = tideTimeEven.first();
Element thirdTideTime = tideTimeOdd.get(1);
Element fourthTideTime = tideTimeEven.get(1);
異常情況的原因是某個表中只有3行,而不是4個,在這個秩序; 奇 甚至 奇 甚至
這是最後的「甚至」行導致該問題。
<div class="tide_row odd">
<div class="time">00:57</div>
<div class="height_m">4.9</div>
<div class="height_f">16,1</div>
<div class="range_m">1.9</div>
<div class="range_f">6,3</div>
</div>
<div class="tide_row even">
<div class="time">07:23</div>
<div class="height_m">2.9</div>
<div class="height_f">9,6</div>
<div class="range_m">2</div>
<div class="range_f">6,7</div>
</div>
<div class="tide_row odd">
<div class="time">13:46</div>
<div class="height_m">5.1</div>
<div class="height_f">16,9</div>
<div class="range_m">2.2</div>
<div class="range_f">7,3</div>
</div>
<div class="tide_row even">
<div class="time">20:23</div>
<div class="height_m">2.8</div>
<div class="height_f">9,2</div>
<div class="range_m">2.3</div>
<div class="range_f">7,7</div>
</div>
定義 「一定行」。如果你發佈了一個你正試圖解析的HTML樣本,它可能會有所幫助。 – Josh
由某一行我指的是表中的最後一行,即「偶數」行。將發佈樣本 –
