How update KMLStyle?

[Nejia Ben Nasr]

Hi,

I load feature using KML :

kml= '<?xml version="1.0" encoding="utf-8"?><kml xmlns="http://www.opengis.net/kml/2.2"><Document><Style id="Style1"> <LineStyle> <color>#ffff55ff</color> <width>3</width> </LineStyle> <PolyStyle> <color>#ffffaaaa</color> <fill>1</fill> <outline>1</outline> </PolyStyle></Style><Placemark id="0"> <styleUrl>#Style1</styleUrl> <Polygon> <extrude>0</extrude> <tessellate>0</tessellate> <altitudeMode>clampToGround</altitudeMode> <outerBoundaryIs> <LinearRing><coordinates> 10.17412778,36.84672090 10.17424823,36.84674061 10.17427628,36.84663085 10.17415582,36.84661114 10.17412778,36.84672090</coordinates></LinearRing> </outerBoundaryIs> </Polygon> </Placemark> </Document></kml>'

var oKmlObject = ge.parseKml( Kml ) ;

if( oKmlObject ) {

ge.getFeatures().appendChild( this.oKmlObject ) ;

}

I want to repalce the KMLStyle by this :

kml= '<Style id="Style1"> <LineStyle> <color>#ff00ffff</color> <width>1</width> </LineStyle> <PolyStyle> <color>#ffffaaaa</color> <fill>0</fill> <outline>1</outline> </PolyStyle></Style>'

the code below does not work :(

var oOldStyle = this.oKmlObject.getElementById( sID ) ;

var oNewStyle = ge.parseKml( Kml ) ;

ge.getFeatures().replaceChild( oNewStyle, oOldStyle );

please any one can help me!

Hi.

One problem is your using '#' prefix to the color values in your style as typically used for HTML pages.

Color in KML does not have the '#' prefix. Remove the '#'.

      <Style id="Style1">

            <LineStyle>

                <color>ff00ffff</color>

                <width>1</width>

            </LineStyle>

            ...

        </Style>

Hi Jason,

I modify color (without # prefix), but this doesn't resolve my problem.

the line below it generate an exception (Error: Error calling method on NPObject!)

ge.getFeatures().replaceChild( oNewStyle, oOldStyle );

[Jason M]

kml= '<Style id="Style1"> <LineStyle> <color>#ff00ffff</color> <width>1</width> </LineStyle> <PolyStyle> <color>#ffffaaaa</color> <fill>0</fill> <outline>1</outline> </PolyStyle></Style>'

var oNewStyle = ge.parseKml( Kml ) ....

oNewStyle is probably not a Style object since a KML style must be contained within a Document container.

Instead of trying to parse a Style from KML string suggest you just create Style object directly using API:

https://developers.google.com/earth/documentation/reference/interface_kml_style

var oNewStyle = ge.createStyle('');

var lineStyle = oNewStyle.getLineStyle();

lineStyle.setWidth(1);

lineStyle.getColor().set('ff00ffff');

var polyStyle = oNewStyle.getPolyStyle();

polyStyle.getColor().set('ffffaaaa');

etc.

Thank you Jason :), your last post solve my problem.
