Question

How can I do this in javascript?

$name = $xml->name;
$file_name = strtolower($name);
$file_name = str_replace(array('-','  ',' ','å','ä','ö'), array('',' ','-','a','a','o'), $file_name);
$file_name = preg_replace("/[^a-z0-9-]+/i", "", $file_name);

Mozilla has an amazing reference readily available to you. I’ve included some link in my response below.

Have a look at toLocaleLowerCase for lower casing your string. Then move on to replace which is really in many ways very similar to preg_replace in that it is primarily based on regular expressions.

Lots of reading, but it shouldn’t be too hard! Good luck!
