Get data between comments html dom parser

Question

I am trying to scrape the plain text between 2 comments. I have seen a couple other posts here using next sibling or get child but those seem to rely on finding another HTML tag. This data is just plain text. Parse between comments in Simple HTML Dom

Is it possible with HTML Dom Parser?

<!-- Data starts here -->

<!-- Data ends here -->
</p>

You can read the HTML as a long string then search the string for the start/end JS comment tags and only get the string value in between — Peter

Keep it simple, man. It will be faster and simpler just to process this as text. You can slice the text by finding the positions of the two comments using the strpos function.

if php then so easy

$sample_data="<!-- Data starts here -->asdasdasdasd<!-- Data starts here -->";
$ayrac="<!-- Data starts here -->" //or '--' whatever
$array_for_dta=explode($ayrac,$sample_data);
foreach($array_for_dta as $val){
    if(empty($val)){continue;}
    $data_val=$data_val.$val;
}
echo $data_val;//asdasdasdasd

Really ugly but this works for me. Thanks to Gedrox for the push in the right direction.

Going to test Hakan Kuru answer which looks like it will work as well.

<?php 
$url = 'http://www.aviationweather.gov/metar/data?ids=ksna&format=raw&hours=0&taf=off&layout=off&date=0';
$content = file_get_contents($url);
$start   = '<!-- Data starts here -->';
$end = '<br /><hr width="65%"/>';
$pos = strpos($content, $start);
if ($pos === false) {
    echo "The string '$start' was not found in the string ";
} else {
    echo "The string '$start' was found in the string ";
    echo " and exists at position $pos";
}
$pos2 = strpos($content, $end);
if ($pos2 === false) {
    echo "The string '$end' was not found in the string ";
} else {
    echo "The string '$end' was found in the string ";
    echo " and exists at position $pos2";
}
$count1 = $pos2-$pos;
echo "count: ";
echo $count1;
$posnew = $pos + 25;
$count1new = $count1 - 25;
$metartext = substr($content, $posnew, $count1new);
echo $metartext;
?>

ı think need jquery; try this

  $('p').each(function(a,aa){
    if($(this).attr('clear')){
        var dt=$(this).text();
        alert(dt);
      }
       });

It's a PHP question. No, you don't need jQuery.

You can use jQuery for this as :

<script>
    jQuery(document).ready(function(){
        var text = jQuery("p").html();
        alert(text);
        jQuery(".test").html(text);
    });
</script>
