A possible issue with Multi-geometries and Name and Description inside KML Plugin?

[ismail44]

(Using KML Plugin version from Master)

We have an internal service that creates a KML which we try to display on our map. This KML has a name and description element inside of a Placemark that is defined as a Multigeometry. It seems that inside the parsePlacemark it recurses back into the parsePlacemark function with the "Multi-type" elements. These elements, subsequently don't have the Name and/or Description fields.

Is this non-standardized KML which I just have to account for, or is this an issue with the KML plugin?

I do not have a KML sample which I can post here as it's on a closed system. I could, however, try to fashion a sample, but basically it's just a <Placemark> element with <Name> and <Description> and <Multigeometry> and children (at the same level).

Thanks.

You should have a look at KML specs and provide a jsfiddle reproducing the bug ;)

I looked at the KML specs and while the words appear to be in English, I
don't think they are. I'll see if I can find a few minutes to throw up a
fiddle. I was more curious than anything. And, like I said... the KML we
have is on a closed network that I CANNOT make public, so it's going to be
very difficult for me to do this. But, I'll see what I can do.

Also, is there a reason the description is not shown if there's no name for
the Placemark?

Mainly historical reason, see :

https://github.com/shramov/leaflet-plugins/blob/master/layer/vector/KML.js#L289

Maybe we can change this, feel free to provide a pull request for that.

Thanks!

I am trying to create a fiddle for the original issue... how do I add your KML plugin? Is there a CDN link?

[brunob]

No CDN for now, there is a PR for that on cdnjs/cdnjs#6137 but it's done yet, so you have to use direct link to raw file from here.

[ismail44]

Here is the fiddle for the initial question:

http://fiddle.jshell.net/kybp2dcd/32/

The KML with name and description OUTSIDE of the multigeometry is at:

https://gist.githubusercontent.com/ismail44/880dfedaed05186f14ff/raw/58a6c986cc50bb21a9eaea5d5f2d534fe0fed234/gistfile1.txt

When you try to click on the marker (or the polygon) you don't see the name or description.

Thanks.

Hmm strange but your fiddle doesn't show any map... am i missing something ?

[ismail44]

For some reason there's an SSL error on the site for the leaflet code. Let
me see what I can do.

I removed the "https" bits... try this link:

Still no map...

[ismail44]

HMMM

Then I don't really know what to do. Is there a fiddle you use when demoing
(with leaflet v.0.7.7) that I can clone?

Can you verify that when you go to the fiddle you are connecting to fiddle.net over the standard http port and not the https port? (Meaning, make sure it's http and not https). I just realized I copied the wrong address... try this one:

I have the same problem. I'm using the url: http://gis.hamweather.net/kml/hwadv_all.kml fi you want to reproduce the problem. So I hacked the parsePlacemark function to remove the recursion (after line 247):

        var layers = [];

        var multi = ['MultiGeometry', 'MultiTrack', 'gx:MultiTrack'];
        for (h in multi) {
            el = place.getElementsByTagName(multi[h]);
            for (i = 0; i < el.length; i++) {
//              return this.parsePlacemark(el[i], xml, style, opts);
                var parse = ['LineString', 'Polygon', 'Point', 'Track', 'gx:Track'];
                for (j in parse) {
                    var tag = parse[j];
                    el = place.getElementsByTagName(tag);
                    for (i = 0; i < el.length; i++) {
                        var l = this['parse' + tag.replace(/gx:/, '')](el[i], xml, opts);
                        if (l) { layers.push(l); }
                    }
                }
            }
        }

I'm not sure if this conforms to the KML spec...
