LibreOffice writer 允许用户在文本中插入注释（注释/评论）。

我的问题是我找不到访问特定行注释内容的方法。
以下 python 代码查找选定/突出显示的文本，然后删除除格式化时间代码（例如 01:10:23 或 11:10）之外的所有内容，并将其转换为秒。
如果没有选择文本，它将选择整个当前行并尝试查找时间码。但是，时间码可以在注释中。

我设法获得了文档中所有注释的列表，在代码开头注释掉了，但这对我没有用。

我一直找不到占卜的方法

a) 当前行是否有注释或
b) 如何访问其内容。

如果有人设法实现了这一目标，我将不胜感激。

枚举注解并使用getAnchor()找出每个注解的位置。此答案基于https://wiki.openoffice.org/wiki/Documentation/DevGuide/Text/Editing_Text#Text_Contents_Other_Than_Strings。

您的代码即将开始工作。

while oEnum.hasMoreElements():
    oField = oEnum.nextElement()
    if oField.supportsService('com.sun.star.text.TextField.Annotation'):
        xTextRange = oField.getAnchor()
        cursor.gotoRange(xTextRange, False)

print (dir(x))XrayTool 或 MRI 等自省工具将提供更好的信息，而不是。它使 API 文档更容易理解。
