正则表达式：匹配特定单词的表达式
[英]Regex : expression to match specific word
问题描述
I have a regex replace function:
我有一个正则表达式替换 function：
reg_replace(Input_Column,'\b(?:(?!https|www|http)\w)+\b', 'x')
With www.google.com input, the result is www.xx where as it should be www.xxxxxx.xxx .使用www.google.com输入，结果是www.xx应该是www.xxxxxx.xxx 。
Please help me to write a regex which works by letters and not by words.请帮我写一个通过字母而不是单词工作的正则表达式。
