Set XML-Attributes for multiply objects

Hi everybody,

this is my situation. I have a document with several pages and several objects on each page.

now I want to get the coordinates and the dimensions of a object and write down the datas as a XML-attribute.

The script should do this for every object in my document.

That's what i got so far:

function creatAtt(){

 

    for (var i = 0; i < app.selection.length; i++){

 

    var myObject     = app.selection[i];

    var myXMLobject = myObject.associatedXMLElement;

 

    var ycoords     = myObject.geometricBounds[0];

    var xcoords     = myObject.geometricBounds[1];

    var width         = myObject.geometricBounds[3] - myObject.geometricBounds[1];

    var height         = myObject.geometricBounds[2] - myObject.geometricBounds[0];

 

    myXMLobject.xmlAttributes.add ("Y-Koordinate", ycoords.toString() + " px");

    myXMLobject.xmlAttributes.add ("X-Koordinate", xcoords.toString() + " px");

    myXMLobject.xmlAttributes.add ("Width", width.toString() + " px");

    myXMLobject.xmlAttributes.add ("Height", height.toString() + " px");

 

    }

}

 

creatAtt();

When I select a object and run the script it only writes the data for the selected object, not for all objects. Somebody a tip how to fix it???
