You have a dot (concatenation operator) after the pattern, rather than a comma.

PS: note that split takes a pattern rather than a string as the regex; if you supply it with a string, that string undergoes normal double-quoted string processing, before belated being passed to the regex engine, which can cause things like \b to be misinterpreted. So get into the habit of using pattern delimiters:

@splitted=split(/\<\/Text\>/, $text);

PPS: my @splitted=[]; doesn't do what you think it does. It is setting @splitted to contain one element, which is a reference to an array. You probably meant my @splitted= (). But that is doubly redundant; firstly the my declaration already creates an empty array, and secondly you immediately assign a new value to the array anyway - the returned list from split - so it doesn't matter if the array wasn't empty before.
