JavaScript: Add Nodes to Current Use Element

To add a node to the current 'useElement', you can use the 'appendChild' method. Here's an example of how you can do it:

for (let i = 0; i < useElements.length; i++) {
    const useElement = useElements[i];
    const xlinkHref = useElement.getAttribute('xlink:href');
    const newxlinkHref = xlinkHref.replace('#', '');

    // Create a new node
    const newNode = document.createElement('circle');
    newNode.setAttribute('cx', '50');
    newNode.setAttribute('cy', '50');
    newNode.setAttribute('r', '20');
    newNode.setAttribute('fill', 'red');

    // Append the new node to the useElement
    useElement.appendChild(newNode);
}

In this example, a new <circle> element is created and appended to each 'useElement'. You can customize the attributes of the new node according to your needs.
