我有以下html表，我试图使用JSoup解析。
我正在解析它如下;
Elements table = document.select("table[class=MsoNormalTable]");
Elements tbody = table.select("tbody");
Elements tr = tbody.select("tr");
Elements td = tr.select("td");
Elements tableHeaders = td.select("p[class=MsoNormal]");
我怎样才能找出每个表体有多少表行？

只需使用尺寸方法。 document.select("table[class=MsoNormalTable] tbody")语句给出了所有tbody和形式，如果你选择tr并检查大小，你就会得到这个数字。
迭代每个tbody并获得像
这样的大小Elements tables = document.select("table[class=MsoNormalTable] tbody");
int index = 0;
for(Element table : tables){
System.out.println("Table : " + (++index) + " has " + table.select("tr").size() + " rows.");
}

根据JavaDoc，此元素列表中的select()＆＃34; Find [s]匹配元素＆＃34;，表示返回仅限于您所在元素下的DOM元素搜索（如限制），size()返回接口Collection＆＃34;中的＆＃34;大小。这似乎表明在给定的DOM元素上使用select()后跟返回size()上的Elements将为您提供由Elements返回的所有tbody的大小/计数选择。您正在选择具有＆＃39; MsoNormal＆＃39;类的所有表，我在您的示例中看到的是3个表。然后，您获得tr，然后是td，然后是tbody。您基本上是获取所有表（至少是您显示的表），然后是所有tr，然后是所有tr等，等等。如果您想将计数限制为仅table位于单个表中，然后您需要将正在搜索的内容（即List<Element> s）限制为您要计算的单个表。
如果无法做到这一点，请从table选择中获取Elements，循环浏览每一个，然后使用Element选择将搜索限制为仅限于元件。这只是阅读API并弄清楚你需要做什么的问题。是否要单独搜索您返回的Element或{{1}}？
