我的学校为我提供了以下时间table（如上所示），但是当我想使用简单htmldom 解析table 时。从此 table 我想收集数据以便我可以在我的应用程序中使用它。

我可以使用简单htmldom 中的什么查询来仅select 前table 行？像这样：Table->(所有行)

当我尝试此查询时：echo($html->find('table tr',0)); 并且我将零更改为 2（例如），它不会 return 主行的下 table 行 table。但相反，它 return 是第一 table 行中子 table 的第一 table 行。

并不是说我不能改变 table 的显示方式，这是我必须使用的 table。

我现在执行时得到的结果：echo($html->find('table tr',2)); -> "Maandag"

我想得到什么：<tr><td rowspan="2" align="center" nowrap="1"><table><tbody><tr><td align="center" nowrap="1"><font size="2" face="Arial"> <b>2</b> </font> </td> </tr></tbody></table></td> <td colspan="12" rowspan="2" align="center" nowrap="1"><table><tbody><tr><td></td></tr></tbody></table></td> <td colspan="12" rowspan="2" align="center" nowrap="1"><table><tbody><tr><td width="33%" nowrap="1"><font size="2" face="Arial"> *in_3. </font> </td> <td width="33%" nowrap="1"><font size="2" face="Arial"> O114 </font> </td> <td width="33%" nowrap="1"><font size="2" face="Arial"> V4B </font> </td> </tr><tr><td colspan="3" width="33%" nowrap="1"><font size="2" face="Arial"> V4C </font> </td> </tr></tbody></table></td> <td colspan="12" rowspan="2" align="center" nowrap="1"><table><tbody><tr><td width="33%" nowrap="1"><font size="2" face="Arial"> *in_7. </font> </td> <td width="33%" nowrap="1"><font size="2" face="Arial"> O112 </font> </td> <td width="33%" nowrap="1"><font size="2" face="Arial"> V4B </font> </td> </tr><tr><td colspan="3" width="33%" nowrap="1"><font size="2" face="Arial"> V4A </font> </td> </tr></tbody></table></td> <td colspan="12" rowspan="2" align="center" nowrap="1"><table><tbody><tr><td></td></tr></tbody></table></td></tr> （第一个（主要）的下 table 行 table）

我在html中加载的方式 table:

$html = file_get_html($timetableURL);
$timeTable = $html->find('table',0); //I need to do this because the page with the timetable has more html tables, I tested this and it always fetches the timetable as seen above.

相关问题：PHP Simple HTML DOM Parser how to get TR only from first table 只有我想select第一个table的第二行或第三行。

echo($timeTable->find('tr',2));

Answer 1

您可以使用 jQuery 选择器 :first 从 DOM

中获取第一个元素

你可以这样做：

$(function() {
 var table = $('table:first');
 var table_rows = table.find('tr');
 alert(" There are " + table_rows.length + " rows in Table");
});

Answer 2

有点绕口简单-html-dom:

// find the first table
$table = $html->find('table', 0);

// iterate all tr's
foreach($table->find('tr') as $tr){

  // skip the tr's that are not top level
  if($tr->parent->parent != $table) continue;

  do_something_with($tr);
}

Answer 3

遍历你的 DOM 结构，我发现你想要的 tr 是第 4 个子 tr，它直接在 table 下的 tbody 元素下.

所以，您需要的查询可能是这样的

// assume table is the root/parent DOM
$tr = $table->find('tbody > tr:nth-child(4)');
var_dump($tr->html());

Answer 4

我使用了 while 循环和简单的-html-dom nextSibling() 函数。

$tableCell = $row->find('td', 0);
while($tableCell){
   $tableCell = $tableCell->next_sibling(); //Go to the next tableCell
}

仅获取第一个 table 中的 table 行 - 简单 HTML Dom (PHP)

Get only the table rows from the first table - Simple HTML Dom (PHP)
