正则表达式匹配字符串中的非常出现

Question

I have a string "Format: Multiple videos Length:20 mins ....Format: Video with Length: 50 mins" and want to enclose "Format ...mins" part in a tag eg

"<p>Format: Multiple videos Length:20 mins</p> ....<p>Format: Video with Length: 50 mins</p>"

The regex I have in Coldfusion is

<cfset str= reReplace(str, "Format:(.*?)Video(.*?)mins", "<p>Format:\1Video\2mins</p>", "ALL")>

but I get output as

"<p>Format: Multiple videos Length:20 mins ....Format: Video with Length: 50 mins</p>"

What is the proper regex to match every occurrence in the string?

Answer 1

You can use

REReplaceNoCase(str, "Format:((?:(?!Format:|Video|mins).)*)Video((?:(?!Format:|mins).)*)mins", "<p>Format:\1Video\2mins</p>", "ALL")

See the regex demo .

Details :

• REReplaceNoCase - case insensitive regex replace function
• Format: - a fixed string
• ((?:(?!Format:|Video|mins).)*) - Group 1: any text up to the first Video that has no Format: , Video and mins substrings
• Video - a fixed string
• ((?:(?!Format:|mins).)*) - Group 2: any text up to the first mins that has no Format: and mins substrings
• mins - a fixed string
