[ka-Map-users] XMLOverlay Multiple Items at Same Point

[Ghulam Muqtada]

 Wayne, I am not constructing  XML document that has tags like
 
<overlay><point x="7435386.24" y="6172463.1" id="p1"><label>just a label</label><symbol shape="bullet" size="10" opacity="1" color="#FF0000" /></point></overlay>
but  I am  creating kaXmlPoints manualy and adding it to XmlOVerlay like
var my_poin = myXmlOverlay.addNewPoint('p1',349,786);var my_label= new kaXmlLabel();var my_icon= new kaXmlIcon();my_label.text='Title One';my_label.boxcolor='#ff0000';my_label. h='10';my_label. w='50';my_label.font='Aria';my_label.color='#000000';
my_icon.icon_w='20';my_icon.icon_h='41';my_icon.icon_src='images/bullet.gif';my_icon.draw(my_point);my_label.draw(my_point);
above code works fine on index_overlay.html when i call it on some event, but i want to have this thing in setInterVal , above code is written in  some seperate PHP file that generates it.
What I guess is loadXml requires xml URL  and my PHP file is not generating XML tags rather it creates kaXmlPoint directly.
 
 
Regards
Ghulam Muqtada
