use Gedcom::Grammar; my $st = $grammar->structure("GEDCOM"); my @sgr = $grammar->item("DATE"); my @items = $grammar->valid_items; my $min = $grammar->min; my $max = $grammar->max; my @items = $grammar->items; DESCRIPTION
A selection of subroutines to handle the grammar of a gedcom file. Derived from Gedcom::Item. HASH MEMBERS
Some of the more important hash members are: $grammar->{top} The top of the grammar tree. $grammar->{top}{structures} A reference to a hash mapping the names of all structures to the grammar objects. METHODS
structures my $st = $grammar->structure("GEDCOM"); Return the grammar item of the specified structure, if it exists, or undef. item my @sgr = $grammar->item("DATE"); Return a list of the possible grammar items of the specified sub-item, if it exists. min my $min = $grammar->min; Return the minimum permissible number of $grammar items max my $max = $grammar->max; Return the maximum permissible number of $grammar items items my @items = $grammar->items; Return a list of tags of the grammar's sub-items valid_items my @items = $grammar->valid_items; Return a hash detailing all the valid sub-items of the grammar item. The key is the tag of the sub-item and the value is an array of hashes with three members: grammar => the sub-item grammar min => the minimum permissible number of these sub-items max => the maximum permissible number of these sub-items perl v5.14.2 2012-04-12 Gedcom::Grammar(3pm)
