Id like to be able to convert the following XML
<itunes:duration>00:09:54</itunes:duration>
To a total of minutes, I currently just output the complete value but I would like to just display: 0hr 9min 54sec
Or possibly round up to the nearest minute?
If you're using an XPath 2.0 supporting processor, there are built in functions you can use. Here's a list, scroll down to the date/time functions.
You probably want something like: minutes-from-time(time)
Watch out for namespace prefixes etc. A prefix isn't required for the functions if your processor dows support XPath 2.0
If you just want to round up you can substring minutes and seconds, and if seconds > 30 -> minutes += 1
