我需要帮助解析使用JSoup的这个html。我试图从表中的每一列获取数据值。我一直在查看JSoup文档，试图找出我究竟需要做什么，但仍然不确定。看起来该网站使用CSS和内联格式的组合;其中大部分可以转换为CSS并减少页面大小。
这是html文件的一小部分（实际上它的大小几乎是5 MB）。

这是我的Parse类
public static class Parse {
public static ArrayList<Player> playerList(Document doc) {
ArrayList<Player> players = new ArrayList();
try {
Elements trs = doc.select("tbody tr");
for (Element tr : trs) {
Elements tds = tr.getElementsByTag("td");
Element td = tds.first();
System.out.println("Blog: " + td.text());
}
} catch (Exception e) {
e.printStackTrace();
}
return players;
}
}
更新：我已更新源代码，以更准确地显示html的结构。我曾假设 tbody 会出现在表元素中。我想我错了，对不起。

所以我在解析你提供的代码片段时遇到了一些困难，因为缺少了表元素标记，但是一旦我添加了我就能够使用以下逻辑获取每列中的文本：
public static void main(String args[]) {
String html = "<html> <head></head> <body> <table>\n" +
"<tbody>\n" +
"<tr bgColor=\"white\" class=\"ESP\">\n" +
" <td width=20 height=30> 1 </td>\n" +
" <td width=20><b class=\"smalltxt\"> </b><b class=\"chigh\"> CH </b><b class=\"smalltxt\"> </b></td> <td><div class=\"spr esp\"></div></td> \n" +
" <td width=150>Rafael Nadal</td> \n" +
" <td width=50>31<span style=\"font-size:66%\">.6</span></td> \n" +
" <td width=80>ESP<span style=\"font-size:66%\">1</span></td> \n" +
" <td width=50>9580</td> <td align=\"center\">-</td> \n" +
" <td align=\"center\"><b class=\"smallred\">-1020</b></td> \n" +
" <td class=\"hdcol\" align=\"center\" width=320>Australian Open R16<br> (R32 <a href=\"\" onclick=\"playVideo('6i9o76bE4vM' );return false;\" > <img width=20 src=\"/youtube-logo-play-icon.png\" style=\"vertical-align:middle;margin-top:-2px\";></a>)</td> \n" +
" <td class=\"hdcol\" align=\"center\" width=320>-</td> <td class=\"shcol\" align=\"center\" width=320>Australian Open R16<br> (R32 <a href=\"\" onclick=\"playVideo('6i9o76bE4vM' );return false;\" > <img width=20 src=\"/youtube-logo-play-icon.png\" style=\"vertical-align:middle;margin-top:-2px\";></a>)</td> \n" +
" <td width=50>9760</td> <td width=50>11400</td> \n" +
"</tr>\n" +
"</tbody>\n" +
"</table>\n" +
"</body>\n" +
"</html>";
Document document = Jsoup.parse(html);
Elements data = document.select("body > table > tbody > tr > td");
for (Element value : data) {
System.out.println(value.text());
}
}
答案 1 :(得分：0)
此代码将成功读取您问题中提供的HTML中的表格内容：
String html = "your html";
Document doc = Jsoup.parse(html);
try {
// select the table
Elements table = doc.select("table");
// select all rows in the table
Elements trs = table.select("tr");
for (Element tr : trs) {
// select all cells in this row
Elements tds = tr.getElementsByTag("td");
for (Element td : tds) {
// print out the cell content
System.out.println(td.text());
}
}
} catch (Exception e) {
e.printStackTrace();
}
鉴于您的问题中提供的HTML，此代码将打印出来：
