Multi-line match according to specific rules

How do I match any line containing #Test and also all next lines from it as long they start with:

• any amount of space followed by a ;

Example:

 1.        ; #Test
 2.        ; bbbb
 3.    
 4.        ; #Test
 5.
 6.        ; aaa

Line 1 and 2 are one match, line 4 another match

This is what i got atm:
\s*(#Test).*(\s*;.*)*

My current doubt is how to stop matching when an empty line is found.

Example2:

 1.        ; #Test
 2.        ; bbbb
 3. 
 4. xxxx
 5. ; #Test
 6. yyyy
 7.
 8.    ; #Test
 9.
 10.   ; bbb

Line 1 and 2 are one match

Line 5 another match

Line 8 is another match.

>Solution :

The problem with your RE is that \s also matches newlines.

You need to use a regular expression that is explicit about newlines, since you have specific requirements about them.

So I would use [ \t]* to match spaces and tabs, instead of \s*:

[ \t]*(#Test).*(\n[ \t]*;.*)*

PS: Make sure you don’t use the s option (single line) because then . will start matching the newline character too.
