    parse itunes extension xml tags

    what is the standard way to get information from an itunes extension tag in a rss feed?

    For example I have a feed that includes <itunes:duration>5:04</itunes:duration>

    I get an error if I try to parse with:

    duration = items[i].getElementsByTagName("itunes:duration")[0].firstChild.nodeValue;

    This code generates:
    items[i].getElementsByTagName("itunes:duration")[0] has no properties.

    Re: parse itunes extension xml tags

    Hi hp3,

    is the iTunes namespace correctly specified? You should have something like this:
    Code:
    <rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" version="2.0">
    Also is your XML correctly parsed (apart from your problem with iTunes tag)?

    Re: parse itunes extension xml tags

    the rss feed has the following:

    <rss xmlns:npr="http://www.npr.org/rss/" xmlns:nprml="http://api.npr.org/nprml" xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" xmlns:content="http://purl.org/rss/1.0/modules/content/" version="2.0">

    I am testing in Firefox and have no problem with other tags in the xml file. Just the itunes tags.

    Uhm... I've done some tests but could not reproduce your issue. Maybe you could post your XML+JS code to directly test it?

    You should use getElementsByTagNameNS instead, e.g.:

    getElementsByTagNameNS("http://www.itunes.com/dtds/podcast-1.0.dtd", "duration")

    For more information, see:
