问题描述
我有一个 .docx 文档，其中 XWPFRun 运行元素之一包含 mc:AlternateContent 和 mc:Fallback 元素。有没有办法让poi 5解析mc:Fallback元素的内容？
如果我理解 .docx 格式正确，那么解析器应该读取 mc:Fallback 的内容并使用该内容而不是 mc:AlternateContent 的内容，但就我所见，poi 并没有这样做。它只是忽略整个
所以我的问题是“有没有办法让 poi 解析 mc:Fallback 中的 xml”？
如果这是不可能的，我想我将不得不自己为这种特殊情况解析xml。但后来我遇到了问题：我该怎么做？ XWPFRun类没有获取所有childern的方法，所以好像没有遍历树或者直接解析xml的方法？。
运行的xml是：
