In the past with Dede collection, always filter not off more than one line of code, only a row of filtering, on the Internet, found there are many and I like the rookie. With the constant use of Dede acquisition, there is a further understanding of the regular, and now I use a regular expression, the same can match multiple lines of code.
For example, in the following code, filter out a hyperlink with two lines of code.
Xxx
Xxx
Multi-line matching can be achieved with the following filter
{Dede:trim} ([^\n<]*) {/dede:trim}
A sign like this can be used as a newline character, and a \ n represents a newline.
Hope to be useful to beginners Dede.
