Re: [Exist-open] Still trying to validate an XML Schema

[Ted H. <meg...@gm...>]

Good afternoon.  I finally took a better look at my code and noticed that
my file had been saved as an Xquery instead of a Javascript file.  So I
copied and pasted my text to a new file.  I destroyed the old file and
renamed the new file.  That took care of the previous error.  Now I have a
different error.  It's called an assignment in a conditional error.  Here
is the code again if you need to see it.

var SVG_Data;
var Retrieved_Data;
var Attribute_List;
var Coordinate_List;
var Counter;
function Setup() {
     SVG_Data = new XMLHttpRequest();
     SVG_Data.open("GET","
http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Ellipse.xq",
true);
     SVG_Data.onreadystatechange = function () {
         if (SVG_Data.readyState = 4) {
            Retrieved_Data = SVG_Data.responseText;
            Retrieved_Data = Retrieved_Data.split("*");
            Attribute_List = "";
            Coordinate_List = "";
            for (Counter = 0; Counter < 8; Counter++) {
      Attribute_List = Attribute_List + Retrieved_Data[Counter] + "*";
  Counter = Counter + 1;
  Coordinate_List = Coordinate_List + Retrieved_Data[Counter] + "*";}
  Attribute_List = Attribute_List.split("*");
      Coordinate_List = Coordinate_List.split("*");
      Coordinate = "<ellipse id = 'My_Ellipse'";
    for (Counter = 0; Counter < 4; Counter++) {
         Coordinate = Coordinate + " " + Attribute_List[Counter] + " = '" +
Coordinate_List[Counter] + "'";}
    Coordinate = Coordinate + ">";
     document.getElementById("Image_Box").innerHTML = Coordinate;
         }
     };
}
   SVG_Data.send();
