not able to retrieve direct child elements using Simple HTML DOM

Question

I have an html table like this

<table>
<tbody>
    <tr>
      <td><table>
          <tbody>
            <tr class="prdLi">
              <td rowspan="2" class="prdNo"><span>310.</span></td>
              <td colspan="2" class="prdDe" rowspan="2"><span>Pepsi</span></td>
            </tr>
            <tr class="prdLi">
              <td class="prdAc"><span> 1.5L</span></td>
              <td><span>&nbsp;</span></td>
            </tr>
          </tbody>
        </table></td>
    </tr>
  </tbody>
</table>

the table is saved as $html

I want to select the child elements of the class .prdLi

I tried like this:

foreach($html->find('tr.prdLi') as $foo){
   echo $foo;

}

the output that i get is like this

<span>310.</span>
<span>Pepsi</span
.
.
.

but what i actually want to get is the code with the parent element td.like this:

<td rowspan="2" class="prdNo"><span>310.</span></td>
<td colspan="2" class="prdDe" rowspan="2"><span>Pepsi</span></td>
.
.
.

please help me

What parser are you using, i.e. what is the type of `$html`? — andy, Oct 13 '14 at 11:36
so you want an echo with that literal tags? inside of the node values? — Kevin, Oct 13 '14 at 11:40
can you explain what is the purpose this? you just want to echo it? — Kevin, Oct 13 '14 at 12:11
@andy it was obtained using the `find()` in Simple HTML Parser, from higher elements in the DOM — Ali Dru, Oct 13 '14 at 12:12
@Ghost no. i wanted to make the selection of the child elements inside the class `prdLi` and then use those elements to further obtain the data inside the `td`tags with the class names. I need the class names of `td` to select the data. but what im getting instead is the child elements of `td` as `....` — Ali Dru, Oct 13 '14 at 12:21

Since Simple HTML DOM Parser supports CSS like selectors, you can use 'tr.prdLi td' to specify all td elements which are children of tr with class prdLi. The following should provide what you are looking for:

$htmlstr = <<<EOD
<table>
<tbody>
    <tr>
      <td><table>
          <tbody>
            <tr class="prdLi">
              <td rowspan="2" class="prdNo"><span>310.</span></td>
              <td colspan="2" class="prdDe" rowspan="2"><span>Pepsi</span></td>
            </tr>
            <tr class="prdLi">
              <td class="prdAc"><span> 1.5L</span></td>
              <td><span>&nbsp;</span></td>
            </tr>
          </tbody>
        </table></td>
    </tr>
  </tbody>
</table>
EOD;

$html = str_get_html($htmlstr);
foreach ($html->find('tr.prdLi td') as $foo) {
    echo $foo . "\n";
}

Note that find() is called on the main simple_html_dom-element. In your example, the result was already limited by a previous find().

but the output is as before, like this: `310. Pepsi310. Pepsi` — Ali Dru, Oct 13 '14 at 12:28
I tested the above code with version 1.5 ($Rev: 210 $) of the parser and get exactly what you are looking for. Which code exactly are you using? What version or the parser? — andy, Oct 13 '14 at 12:31
im using the same version as yours `version 1.5 ($Rev: 210 $)` — Ali Dru, Oct 13 '14 at 12:38

What andy says is correct, but the css for direct child is > *, therefore:

foreach($html->find('tr.prdLi > *') as $foo){
   echo $foo . "\n";
}

Simple HTML DOM does not support child selectors. – Leo Oct 25 '16 at 16:03
