动态类的Google跟踪代码管理器选择器

Question

我正在尝试将href值存储为GTM DOM变量这是源代码。

    <div class="top-menu-bar">
            <div class="container">
                <div class="top-menu">
                                            <div class="menu-ar-secondary-menu-container"><ul id="menu-ar-secondary-menu" class="menu"><li id="menu-item-818" class="mobile_menu top-menu-btn orange menu-item menu-item-type-custom menu-item-object-custom menu-item-818"><a href="https://apply-gm.sample.com/?lang=AR">افتح حساب حقيقي</a></li>

</ul>
</li>
</ul></div>                                 </div>
            </div>
        </div>  

我面临的问题是类中的数字确实发生了变化，我只想使用“ lang-item-ur”，这是上述html中唯一的静态元素。

我正在使用的选择器是

#menu-item-821 > ul > li.lang-item.lang-item-32.lang-item-ur.menu-item.menu-item-type-custom.menu-item-object-custom.menu-item-821-ur > a 

这将不起作用，因为数字保持不变。

我该如何解决。
