how to get the element id of href

Question

I'm working on my php to get the id of href tags using with DOMDocument.

I'm trying to parse the element with id called <a id="test. When I tried to parse the id, I will get the empty return.

I'm using this:

$domdoc = new DOMDocument();
$domdoc->strictErrorChecking = false;
$domdoc->recover=true;
//@$domdoc->loadHTMLFile($baseUrl);
@$domdoc->loadHTML($baseUrl);

$links = $domdoc->getElementsByTagName('test');
$data = array();
foreach($links as $link)
{
  echo $link;;
}

Here is the output:

echo '<a id="test" href="http://www.mysite.com/script.php?=' . $row["channels"] . "&id=" . $row["id"] . '">http://www.mysite.com/script.php?channels=' . $row["channels"] . "&id=" . $row["id"] . '</a>

Does anyone know how I can get the element with id called <a id="test?

Edit: Here is the update code:

<?php
ini_set('max_execution_time', 300);
$errmsg_arr = array();
$errflag = false;

$xml .= '<?xml version="1.0" encoding="UTF-8" ?>';
$xml .= '
<tv generator-info-name="www.mysite.com/xmltv">';

$baseUrl = file_get_contents('http://www.mysite.com/get-listing.php');

$domdoc = new DOMDocument();
$domdoc->strictErrorChecking = false;
$domdoc->recover=true;
//@$domdoc->loadHTMLFile($baseUrl);
@$domdoc->loadHTML($baseUrl);

//$links = $domdoc->getElementsByTagName('test');
//$links = $domdoc->getElementById('test');
$links = $domdoc->getElementsByTagName('a');

$data = array();
foreach($links as $link)
{

  echo $domdoc->saveXML($link);
}

I think you're using the getElementsByTagName() the wrong way. This method is used to get HTML tags, not their attributes or value of attributes.

Please check the following example:

<?php
$html = '<a id="test" href="#">Some link text here</a>';
$html .= '<a id="test2" href="#">Some link text here</a>';
$DOM = new DOMDocument();
$DOM->loadHTML($html);

$links = $DOM->getElementsByTagName('a');
foreach($links as $link) {
    if( $link->getAttribute('id') == "test" ) {
        echo "<h4>Element with id test Found!</h4>";
        // Or do something else here when you find the element by id="test"
            // As an example for what you're trying from my understanding
            echo $DOM->saveHTML($link);
            // This will echo the node as html back to the browser
    }
}
?>

I used two <a> tags as my HTML input, and searched for the one that has an attribute of id with the value "test".

Update your code.. Work for my :)

<?php
$html = file_get_contents('http://www.serbalucu.com');
$dom = new DOMDocument;
@$dom->loadHTML($html);
$links = $dom->getElementsByTagName('a');

foreach($links as $link) {

    if( $link->getAttribute('class') == "with-ul" ) {
        echo "<h1>RESULT FOUND</h1>";

            echo $dom->saveHTML($link);
    }

}
?>
