The answer is simple.答案很简单。 You must not insert HTML content into the MainDocumentPart because it is expected to contain a valid Open XML w:document element, eg, as the following simplified one:不得将 HTML 内容插入MainDocumentPart因为它应该包含有效的 Open XML w:document元素，例如，如下简化：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<w:document xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">
<w:body>
<w:p>
<w:r>
<w:t>Hello, world!</w:t>
</w:r>
</w:p>
</w:body>
</w:document>
The error message probably is a little misleading.错误消息可能有点误导。 HTML is simply invalid in this case.在这种情况下，HTML 就是无效的。
Depending on whether or not you changed the HTML after creating it (with the Open XML PowerTools) from the original Word document, you will have to either transform it back into valid Open XML markup (if you changed it) or simply use the Open XML markup from the original Word document.根据您在从原始 Word 文档（使用 Open XML PowerTools）创建 HTML 后是否更改了 HTML，您必须将其转换回有效的 Open XML 标记（如果您更改了它）或仅使用 Open XML原始 Word 文档中的标记。
