使用javascript replace方法，我想找到以下字符串：

<span class="memberX"><span class="member19">text</span></span>    <---X is any number

最终输出应为：

<span class="member19">text</span>

本质上，我想删除可以具有memberX类的外部范围，其中X是任何数字。

最佳答案

如果在DOM中，则不需要正则表达式。您应该只操作DOM本身。

var spans = document.querySelectorAll('span[class^=member] > span[class^=member]');

for (var i = 0; i < spans.length; i++) {
    spans[i].parentNode.parentNode.insertBefore(spans[i], spans[i].parentNode);
    spans[i].parentNode.removeChild(spans[i].nextSibling);
}
