将内容片段导出到XML
可以使用headerMenu扩展点将自定义按钮添加到内容片段编辑器标题菜单。 此示例说明如何向标题菜单添加按钮，以及如何处理单击事件以将活动内容片段导出为XML或CSV。
标题按钮可以作为一个按钮存在，也可以作为具有子项目的按钮存在。 此示例说明如何使用子项实施按钮，但包含用于实施单个按钮的注释掉的代码。
扩展点
此示例扩展到扩展点headerBar以将自定义按钮添加到内容片段编辑器。
扩展示例
以下示例创建了一个标头菜单按钮，该按钮具有两个子项，一个用于将活动内容片段导出为XML（已实施），另一个用于将活动内容片段导出为CSV（未实施）。
此代码显示了如何在扩展的注册文件中获取内容片段的内容，以及如何导出内容片段的JSON内容。
延期注册
ExtensionRegistration.js映射到index.html路由，是AEM扩展的入口点，并定义：
- 扩展按钮的位置(
headerMenu)显示在AEM创作体验中 - getButton()函数中扩展按钮的定义
- 按钮的点击处理程序(在onClick()函数中)或子项列表及其点击处理程序。

内容片段数据
可以使用guestConnection.host.contentFragment对象上的getContentFragment()方法检索活动内容片段。
const contentFragment = await guestConnection.host.contentFragment.getContentFragment();
contentFragment对象包含有关内容片段的所有信息，包括路径、模型、元数据、主内容和任何变体。
