xml substitution into http meta refresh - Webmaster Forums - Webmaster forum for HTML, PHP, ASP, CSS and more

I have an XML document

yourboyvic.com/albumart/now_playing.xml

in this XML doc there is an element

<time>

the objective

use this <time> element

in http meta refresh code

<meta http-equiv="refresh" content="30">

so that <time>+1 injected into content

so that instead of content="30"

content="whatever number is <time>+1 on yourboyvic.com/albumart/now_playing.xml"

in short, a code substitution

the end goal, instead of my page refreshing every thirty seconds,

my page refresh countdown will be equivalent to when the current song ends plus one second

so that the albumart showing is always the current song playing

preferably in php+html

kind of like this…

<?php>

$file = file_get_contents("albumart/now_playing.xml");

$time = "";

preg_match("/<time><!\[CDATA\[([^\]]+)\]\]><\/time>/sim", $file,
$time_matches);

if (isset($time_matches[1])) {
$title = $time_matches[1];
}

<html>

<meta http-equiv="refresh" content="" . $time . "">

</html>

?>
