Thank you for the information. I found one error. I'm looking into the other.My main error was that I didn't send it to the correct location. I should have sent it to: http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Data.xq I have a new error.XMLHttpRequest cannot load http://localhost:8080/exist/rest/db/apps/HTML_Student/Database_Example.xq. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.I have no idea what this error is. Can you assist me?
