我希望你们聪明的小伙子能够回答这个谜语。

有一个很棒的小部件，我正在尝试集成到我的网站中。它从文档中的<H1>, <H2>等标签创建菜单。这非常有用，因为我可以通过设置标题样式为每个页面创建子菜单导航。

但是，我使用的是wordpress主题，该主题已将扩展添加到编辑器中，以样式设置页面的各个部分，包括例如标题。

因此，它如何在 HTML 输出中设置标题样式的输出如下所示：

<h1 class="grve-element grve-align-left grve-title-striped" style="">Visit</h1>

我将在下面加载的 PHP 脚本，它似乎抓取标签的相关部分是：

    $tags_to_parse = "<h1>";

有没有办法告诉这个PHP脚本来获取这个特定的H1类？

干杯
