Regular expressions that can filter multiple lines of code in dedecms collection_PHP tutorial

In the past, when I used dede to collect code, I couldn't filter out more than one line of code, and could only filter it line by line. On the Internet, I found that there are many novices like me. With the continuous use of dede collection, I have a better understanding of regular expressions. Now I can even use a regular expression to match multiple lines of code.

For example: In the following code, filter out hyperlinks with two lines of code.


XXX
XXX


Use the following filter to achieve multi-line matching
{dede:trim} ([^n<]*) {/dede:trim}

Symbols like n can be used as line breaks, and an n represents a line break.
Hope it will be useful to those who are new to dede
