gitignore 忽略二级目录中除 config.xml 文件以外的所有文件？

Question

我用谷歌搜索但很难找到合适的解决方案。如果我有以下文件，如何忽略除这三个文件之外的所有文件？

package-01/config.xml
package-02/config.xml
package-03/config.xml

./
|-- .git/
|-- .gitignore
|-- README.md
|-- config.xml
|-- configuration
|-- package-01/
|   |-- settings/
|   |   |-- id
|   |   `-- links
|   |-- config.xml
|   `-- other_files
|-- package-02/
|   |-- settings/
|   |   |-- id
|   |   `-- links
|   |-- config.xml
|   `-- other_files
|-- package-03/
|   |-- settings/
|   |   |-- id
|   |   `-- links
|   |-- external_packages/
|   |   |-- 1/
|   |   |   |-- settings.xml
|   |   |   |-- config.xml
|   |   |   `-- id
|   |   |-- 2/
|   |   |   |-- settings.xml
|   |   |   |-- config.xml
|   |   |   `-- id
|   |-- config.xml
|   `-- other_files

我试过了但是失败了。

*
!.gitignore
!README.md
!/**/*.xml
!**/*.xml
!**.xml
!/*/*.xml
!*/*.xml

排除包含 config.xml 的目录被忽略，然后忽略它们的所有内容但排除每个 config.xml.

/*
!.gitignore
!README.md
!/package-01
/package-01/**
!/package-01/config.xml
!/package-02
/package-02/**
!/package-02/config.xml
!/package-03
/package-03/**
!/package-03/config.xml

正如 ElpieKay 在评论中提到的那样，您的方法确实存在问题：

It is not possible to re-include a file if a parent directory of that file is excluded.
