[Perl] split on : but with extra challenge
Hi,

I am looking for a little bit more advanced split.

Code:

Code:
#!/usr/bin/perl -w #-d
use strict;

my $Line = "value1:{value2a:value2b}:value3:{}:value5:{value6a:value6b}";

my @LineAttributes = split (/:/, $Line);

my $TotalLineAttributes = scalar @LineAttributes;

print "Line: $Line\n\n";
print "Total attributes: $TotalLineAttributes\n\n";

foreach my $Attribute (@LineAttributes) {
  print "Attribute: $Attribute\n";
}

Result:

Code:
Line: value1:{value2a:value2b}:value3:{}:value5:{value6a:value6b}

Total attributes: 8

Attribute: value1
Attribute: {value2a
Attribute: value2b}
Attribute: value3
Attribute: {}
Attribute: value5
Attribute: {value6a
Attribute: value6b}

I would like to see 6 as result.
The length of the line and the number of values my vary.

Any ideas?

Greetings,

Erik

ppi::token::attribute

PPI::Token::Attribute(3)				User Contributed Perl Documentation				  PPI::Token::Attribute(3)

NAME

       PPI::Token::Attribute - A token for a subroutine attribute

INHERITANCE

	 PPI::Token::Attribute
	 isa PPI::Token
	     isa PPI::Element

DESCRIPTION

       In Perl, attributes are a relatively recent addition to the language.

       Given the code " sub foo : bar(something) {} ", the "bar(something)" part is the attribute.

       A "PPI::Token::Attribute" token represents the entire of the attribute, as the braces and its contents are not parsed into the tree, and
       are treated by Perl (and thus by us) as a single string.

METHODS

       This class provides some additional methods beyond those provided by its PPI::Token and PPI::Element parent classes.

       Got any ideas for methods? Submit a report to rt.cpan.org!

   identifier
       The "identifier" attribute returns the identifier part of the attribute.

       That is, for the attribute "foo(bar)", the "identifier" method would return "foo".

   parameters
       The "parameters" method returns the parameter strong for the attribute.

       That is, for the attribute "foo(bar)", the "parameters" method would return "bar".

       Returns the parameters as a string (including the null string '' for the case of an attribute such as "foo()".

       Returns "undef" if the attribute does not have parameters.

SUPPORT

       See the support section in the main module.
