Help needed with XML parser

Added by Michael Hansen over 8 years ago

Hi,

I am trying to parse the following xml file to get the video infos and urls:
http://www.3sat.de/mediathek/rss/mediathek.xml

I tried it the way the wiki is describing it:

var doc = showtime.httpReq(BASE_URL+'mediathek.xml').toString();
            doc = doc.replace(/media:/g,"media_");
        var chan = XML.parse(doc);
        showtime.trace("channel: " + chan.channel);

for (var i in chan.item) {
            var video_url = chan.item[i].enclosure["@url"];
         page.appendItem(video_url, 'video', {
        station:     chan.item[i].title,
        title:       chan.item[i].title,
        description: chan.item[i].description,
        icon:        chan.item[i].media_group.media_thumbnail["@url"],
        album_art:   chan.item[i].media_group.media_thumbnail["@url"],
        album:       '',
        duration:    1234,
                genre:       chan.item[i].media_group.media_category,
        });
    };

But the result is always 'undefined'

Can someone please help me to parse this xml?
Maybe it is too big?

Thank you,
druelie

You need to do it with filterNodes.

yes, I have tried that already, but with the same result.
Can you give an example for that xml please?

Thx druelie

Sure:

        var doc = showtime.httpReq(unescape(url) + '/web/getservices?sRef=' + serviceReference);
        page.loading = false;
        doc = XML.parse(doc);
        var e2services = doc.e2servicelist.filterNodes('e2service');
        for (var i = 0; i < e2services.length; i++) {
             page.appendItem(plugin.getDescriptor().id + ":zapTo:" + url + ':' + escape(e2services[i].e2servicename) + ':' + encodeURIComponent(e2services[i].e2servicereference), "video", {
                 title: e2services[i].e2servicename
             });
        }

thx, from which of your plugins is this, so I can see the full code?

It's from enigma2 but looks like I can just fix your code. Do:

var doc = showtime.httpReq(BASE_URL+'mediathek.xml').toString();
            doc = doc.replace(/media:/g,"media_");
        var doc = XML.parse(doc);
        showtime.trace("channel: " + doc.channel);

var items = doc.channel.filterNodes('item');
for (var i = 0; i < items.length; i++) {
            var video_url = items[i].enclosure["@url"];
         page.appendItem(video_url, 'video', {
        station:     items[i].title,
        title:       items[i].title,
        description: items[i].description,
        icon:        items[i].media_group.media_thumbnail["@url"],
        album_art:   items[i].media_group.media_thumbnail["@url"],
        album:       '',
        duration:    1234,
                genre:       items[i].media_group.media_category,
        });
    };

Enjoy

        page.loading = false;
