regular expressions matching multiline expression

I should match this text using the regex-find tool of the texStudio editor

\begin{displaymath}
\DIFdel{

The problem is that I don't manage to specify the new line (both using the option "dotall" or not). I tried with the pretty generic reference pattern:

\\begin\{displaymath\}(\s\S\n\t\r\v)*\\DIFdel\{

but is nnot working (of course the pattens "\begin{displaymath}" and "\DIFdel{" match the single parts on the two lines)

Your regex must be,

\\begin\{displaymath\}[\s\S]*\\DIFdel\{

or

\\begin\{displaymath\}\s*\\DIFdel\{

\s\S\n\t\r\v expects all the mentioned chars to be present. SO there must be a space char,non-space char,newline.... BUt there actually a newline char only.
