js 给当前的 useElement 添加节点 const svgString = svg xmlns=httpwwww3org2000svg width=11893ex height=2072ex role=img focusable=false viewBox=0 -8339 52567 9159 xmlnsxlink=httpwwww3org1999xlink aria-hidden=

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.
