query html table using xpath - remove td from the result

I have a HTML table with class name list.

I'm using the following query to get the data. 

$elements = $xpath->query("//table[@class='list']/tr/td");
$result = $dom_object->saveHTML($elements->item(0));
var_dump($result);

It works fine. Except that it adds the td in the result.

I mean the result look like this

<td>
result data
</td>

Can someone tell me how to remove the td tag from the result data?

If there is only one text node per cell (ie. no other markup), you can go for

//table[@class='list']/tr/td/text()

which selects all text nodes inside the <td/>. If there is markup but still only a single text node like in <td><em>foo</em></td>, you could use

//table[@class='list']/tr/td//text()

If it contains more than one text node, you will receive multiple result nodes which are not grouped by table cell any more.

Maybe you're looking for something like

<?php
$doc = new DOMDocument;
$doc->loadhtml( data() );
$xpath = new DOMXPath($doc);
$elements = $xpath->query("//table[@class='list']/tr/td");


// 1)
$result = (string)$elements->item(0)->nodeValue;
var_dump($result);

// 2)
$frag = $doc->createDocumentFragment();
$node = $elements->item(0)->firstChild;
while( $node ) {
    $frag->appendChild( $node->cloneNode(true) );
    $node = $node->nextSibling;
}
$result = $doc->saveXML($frag);
var_dump($result);


function data() {
    return <<< eoh
<html>
    <head><title>...</title></head>
    <body>
        <table class="list">
            <tr><td>result data<br />foo</td></tr>
            <tr><td>...</td></tr>
        </table>
    </body>
</html>
eoh;
}

prints

string(14) "result datafoo"
string(19) "result data<br/>foo"
