我正在为 LibreOffice Writer 创建一个 Basic 宏来检查损坏的内部链接。简而言之:
- 生成所有锚点的列表
- 遍历文档,查找内部超链接
- 如果内部超链接不在锚列表中,打开它进行编辑(并停止)
我的代码有一些未解决的问题:
- (内
fnBuildAnchorList
)我们如何获得每个标题的编号?例如,如果第一个级别 1 标题文本是“介绍”,那么正确的锚点是#1.Introduction|outline
并且我们正在录制Introduction|outline
- (内
subInspectLink
)我们如何正确测试标题的超链接?我注意到,当我手动点击指向标题的链接时,编号相同时它会成功,而且文本相同时也会成功。
例如,如果有内部链接#1.My first heading|outline
,可以通过超链接访问,#1.Previous header name|outline
也可以通过超链接访问#2.3.5.My first heading|outline
- (内
subInspectLink
)我们如何打开特定的超链接进行编辑?我们是否将参数传递给.uno:EditHyperlink
? 我们移动光标吗?(我发现的所有动作都是相对的,例如.uno:GoRight
)我们使用文本部分的.Start
和.End
属性吗?

您可以使用任何带有标题的文档来检查第一个问题——一个带有所有锚点的 MsgBox 会弹出,您会看到缺少的大纲编号。
第二个问题需要一个内部链接错误的文档。
