尝试输出最终的DOM结果

I have search the entire internet, what I have found is getting values of tags with attributes. But I have a tag to extract contents, the tag has no attributes. The tag is cite.

Here is my tag:

<div>
    <cite>My name is Jimmy</cite>
    <cite>My name is Paul</cite>
    <cite>I am Sarah</cite>
</div>

And here is my DOM call:

$dom = new domDocument; 

/*** load the html into the object ***/ 
@$dom->loadHTML($html);

/*** discard white space ***/ 
$dom->preserveWhiteSpace = false; 

/*** the table by its tag name ***/ 
$tables = $dom->getElementsByTagName('cite'); 

/*** loop over the table rows ***/ 
foreach ($tables as $row) {
    /*** get each column by tag name ***/ 
    $cols = $row->getElementsByTagName('cite'); 

    /*** echo the values ***/ 
    echo $cols->textContent.'<br />'; 
}

I get this error:

Notice: Undefined property: DOMNodeList::$textContent

What I would like to get is this:

My name is Jimmy
My name is Paul
I am Sarah

Please guys I need help. Thanks in advance!

$html = "<div>
<cite>My name is Jimmy</cite>
<cite>My name is Paul</cite>
<cite>I am Sarah</cite>
</div>";

$dom = new domDocument; 
$dom->loadHTML($html);
$cities = $dom->getElementsByTagName('cite');
foreach ($cities as $city) {
    echo $city->nodeValue, PHP_EOL;
}

You currently trying to get the tag cite inside each tag cite. Simply remove the second getElementsByTagName in your loop.

foreach ($tables as $row) {
    echo $row->textContent.'<br />'; 
}
