Regex to match character if not between digits（2个答案）
7天前关闭。
假设我有一个文本如下

Lorem Ipsum-is simply dummy- text of the printing and -typesetting industry. 
Lorem Ipsum - has been the industry's standard dummy text ever since the 1500s
a-z

如果-字符不在两个字符（[a-zA-Z]）之间，我想删除它。因此，所需的输出为：

Lorem Ipsum-is simply dummy text of the printing and typesetting industry. 
Lorem Ipsum  has been the industry's standard dummy text ever since the 1500s
a-z

如何编写正则表达式来匹配这种情况？
