Php 如何使用简单的HTMLDOM刮取这两个表？

我一直在试图找出如何使用php simple HTMLDOM来刮取

td class=“job”

及其相应的工资。我可以按id或类查找和删除div，这没问题，但我不知道如何攻击这样的表。任何帮助都将不胜感激

<table cellpadding="0" cellspacing="0" border="0" class="table01">
<tr>
    <td class="head">Test</td>
    <td class="job">
    <a href="/Illustrator" id="UniqueID1">Illustrator</a><br/>
    $23,729 - $95,429
    </td>
</tr>
<tr>
    <td class="head">Test</td>
    <td class="job">
    <a href="/Small_Business_Owner_%2f_Operator" id="UniqueID2">Small Business Owner / Operator</a><br/>
    $24,369 - $174,991
    </td>
</tr>
<tr>
    <td class="head">Test</td>
    <td class="job">
    <a href="/Waiter%2fWaitress" id="UniqueID3">Waiter/Waitress</a><br/>
    $7,483 - $34,188
    </td>
</tr>
</table>

<table cellpadding="0" cellspacing="0" border="0" class="table02">
<tr>
    <td class="head">Test</td>
    <td class="job" style="padding-right: 20px">
    <a href="/Graphic_Artist_%2f_Designer" id="UniqueID1">Graphic Artist / Designer</a><br/>
    $23,789 - $55,409
    </td>
</tr>
<tr>
    <td class="head">Test</td>
    <td class="job" style="padding-right: 20px">
    <a href="/Illustrator" id="UniqueID2">Illustrator</a><br/>
    $23,729 - $95,429
    </td>
</tr>    
<tr>
    <td class="head">Test</td>
    <td class="job" style="padding-right: 20px">
    <a href="/Art_Director" id="UniqueID3">Art Director</a><br/>
    $34,160 - $85,943
    </td>
</tr>
</table>

    // load html
    $dom->loadHTML($html);
    $xpath = new DOMXPath($dom);

    //this will gives you all td with class name is jobs.
    $my_xpath_query = "//table//td[contains(@class, 'job')]";
    $result_rows = $xpath->query($my_xpath_query);

    //iterate all td
    foreach ($result_rows as $result_object){
