Re^2: Counting the start and end elements in a line

When I call the function

counttags(+);

When the script is compiled, I get a error,

Syntax error at vtag.pl at line 275, near "+)"
Execution of vtag.pl aborted due to compilation errors.

On the otherhand, if I have the code as counttags("+");, the $stag and $etag values remain 0.

For you to understand better, the content in the file goes like:
Die Errichtung <I>einer</I> Zweigniederlassung ist durch die Geschäftsführer anzumelden. Der Anmeldung ist eine öffentlich beglaubigte Abschrift des Gesellschaftsvertrages und der Liste der Gesellschafter beizufügen.<+>2</+>

In my function, I am trying to find the number of <I> and </I>, <+> and </+> and check whether the opening and the closing tag count matches.

That's what I expected. You can't just drop an operator in the middle of some source code at random and expect the compiler to know what to do. On the otherhand, if I have the code as `counttags("+");`, the $stag and $etag values remain 0. This is probably because of one of the other errors that have been pointed out to you in this thread. Developing with `use strict` and `use warnings` will almost certainly help you track down problems like this. -- <http://dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply]
