有没有办法使用 jsoup 检查表是否有特定行?
我遇到了一个java.lang.IndexOutOfBoundsException: Invalid location 1, size is 1
例外,我从表格中获取信息的代码是:
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);
发生异常是因为有时该表按此顺序只有 3 行而不是 4 行;奇偶 奇偶
这是导致问题的最后一个“偶数”行。
<div class="tide_row odd">
