Set XML-Attributes for multiply objects

Question

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???

Answer 1

Hi,
I have tried the script. And it only writes down the attributes for one object. Directly in the root. I have attached a screenshot. But i want to write the attributes in the hotspot Tags of the selected object.
I hope you know what I mean .
I dont know where he gets the datas bot that are not the datas of one of my three objects.
I changed the scrip a little bit:
var myDoc     = app.activeDocument; 
var myPages = myDoc.pages;
for (var i = 0; i < myPages.length; i++){
    var myActualPage = myPages[i].pageItems;
    for (var j = 0; j < myActualPage.length; j++){
        var myObject     = myActualPage[j];
        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");
But then I get a error message:
Errornumber: 21
null is not an object.
Row 60 --> He means this part of the script: myXMLobject.xmlAttributes.add ("Y-Koordinate", ycoords.toString() + " px");
