I have some files of this type:

/*  78 */     Lorem ipsum dolor sit amet   
/*  79 */     Lorem ipsum dolor sit amet   
/*  eb */     Lorem ipsum dolor sit amet   
/*  HG */     Lorem ipsum dolor sit amet   
/*     */     Lorem ipsum dolor sit amet  
/*  83 */     Lorem ipsum dolor sit amet   
/*  84 */     Lorem ipsum dolor sit amet  
/*     */ 
/*     */     Lorem ipsum dolor sit amet  
/*  ZX */     Lorem ipsum dolor sit amet  
/*     */     Lorem ipsum dolor sit amet  
/*     */     Lorem ipsum dolor sit amet  
/*  90 */     Lorem ipsum dolor sit amet  
/*  91 */     Lorem ipsum dolor sit amet  
/*  92 */     Lorem ipsum dolor sit amet

And I want to eliminate the 

/*    */ 
/* 10 */

parts of text with regex, my regex looks like: 

[/*(0-9)*/]

but it’s not working properly, it deletes some texts containing numbers

    Everything inside [ and ] is called a character class, which will always match just a single character.

    Inside a character class, the normal regex-meta-chars, like *, ( and ), loose their special powers. So [*] matches just the literal '*'.

    In your case, [/*(0-9)*/] will match one of the following chars: '/', '*', '(', ')', '/' or any (ASCII) digit.

    What you’re looking for is the regex:

    (?m)^/\*[\s0-9]*\*/

    which matches a "/*" followed by zero or more space-chars (\s) or digits (0-9), ending with "*/". The ^ matches the start of the input, and adding a (?m) in front of it makes it match the start of a line.

    So it matches all multi-line comments from your example, except these:

    /*  eb */
/*  HG */
/*  ZX */
