What is the best practice for placing code in HTML for immediate execution after page creation, such as reading XML content for a list?

To execute code immediately after page creation in HTML, such as reading XML content for a list, the best practice is to use JavaScript. By placing the JavaScript code within a `<script>` tag at the end of the HTML body, the code will be executed after the page has loaded, ensuring that all elements are available for manipulation. ```html <!DOCTYPE html> <html> <head> <title>Page Title</title> </head> <body> <!-- HTML content goes here --> <script> // JavaScript code to read XML content and create a list var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { // XML parsing and list creation logic here } }; xhttp.open("GET", "your-xml-file.xml", true); xhttp.send(); </script> </body> </html> ```
