如果您只需要替换文本中间的连字符，那么可以像这样做：
([A-Za-z0-9].*?)-([0-9])
它会捕获两个组，然后将未捕获的连字符“-”替换为“.”，通过将其替换为“$1.$2”。
这通过获取正则表达式的第一部分，然后将其设置回去，然后在“-”的位置放置一个“.”，最后放置第二个捕获组。
这将匹配“HA045141-1”并将连字符替换为点以生成“HA045141.1”。
英文:
If you just need to replace the hyphen in the middle of the text, then you can do something like this
([A-Za-z0-9].*?)-([0-9])
It takes the two capture groups and then replace the not captured - with ., by replacing it with $1.$2.
This works by taking the first part of the regex and then setting it back, and then putting in a . where the - is placed, and lastly placing the second capture group.
This will provide a match for HA045141-1 and replace the hyphen with a dot to make HA045141.1
