我的学校提供我用下面的时间表（如上所示），但是当我想用simplehtmldom解析表。从这张表中我想收集数据，以便我可以在我的应用程序中使用它。

simplehtmldom中的哪个查询可以用来仅选择第一个表格行？像这样：表-1>（所有行）

当我尝试此查询：echo($html->find('table tr',0));我改变了零到2（例如），它没有返回主表的表格下一行。但是，它会返回第一个表格行中的第一个子表格行。

不是说我不能改变表格的显示方式，这是我必须使用的表格。

现在我能得到什么，当我执行：echo($html->find('table tr',2)); - > “Maandag”

我想获得：<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1（主）表的下一tablerow的）

的这样，我在加载HTML表：

$html = file_get_html($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.

一个相关的问题：PHP Simple HTML DOM Parser how to get TR only from first table 只有我要选择例如第一个表的第二行或第三行。

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

你能展示更多吗？比如你如何初始化DOM文档并加载所需的结果。那么，对我来说会更容易。 –

增加了它，我还添加了一个相关的问题，其中有人有同样的问题。 – sloeberGJ

我使用了一个while循环和simple-html-dom nextSibling（）函数。

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

您可以使用jQuery选择:first的第一个元素从DOM

取你可以这样说：

$(function() { 
 
\t var table = $('table:first'); 
 
\t var table_rows = table.find('tr'); 
 
\t alert(" There are " + table_rows.length + " rows in Table"); 
 
});

这不起作用，因为它也选择嵌套表格行（tr）。另外，我不能使用jquery。 – sloeberGJ

这是一个与简单的HTML DOM曲一点点：

// 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); 
}

遍历你的DOM结构，并且我发现你想要的tr是第4个孩子TR，其直属下一个tbody元素table。

所以，你需要查询可能是这样的

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

很抱歉，如果php的语法不正确。这实际上是针对phpquery库进行测试的。
