DESCRIPTION

       A selection of subroutines to handle records in a gedcom file.

       Derived from Gedcom::Item.

HASH MEMBERS

       Some of the more important hash members are:

   $record->{new_xref}
       Used by renumber().

   $record->{recursed}
       Used by renumber().

METHODS

   tag_record
	 my $record  = tag_record("CHIL", 2);
	 my @records = tag_record("CHIL");

       Get specific sub-records from the record.  This function is identical to Gedcom::Item::get_item().

       The arguments are the name of the tag, and optionally the count.

       In scalar context, returns the sub-record, or undef if it doesn't exist.  In array context, returns all sub-records matching the specified
       tag.

   record
	 my @recs = $record->record("birth");
	 my @recs = $record->record("birth", "date");
	 my $rec  = $record->record("birth date");
	 my $rec  = $record->record(["birth", 2], "date");
	 my @recs = $record->get_record("birth");

       Retrieve a record.

       The get_record() function is identical to the record() function.

       In scalar context, record() returns the specified record, or undef if there is none.  In list context, record() returns all the specified
       records.

       Records may be specified by a list of strings.  Each string is either a Gedcom tag or a description.  Starting from the first string in the
       list, specified records are retrieved.  Then from those records, records specified by the next string in the list are retrieved.  This
       continues until all strings from the list have been used.

       In list context, all specified records are retrieved.  In scalar context, only the first record is retrieved.  If a record other than the
       first is wanted, then instead of passing a string, a reference to an array containing the string and a count may be passed.

       Instead of specifying a list of strings, it is possible to specify a single space separated string.  This can make the interface nicer.

   get_value
	 my $val  = $record->get_value;
	 my @vals = $record->get_value("date");
	 my @vals = $record->get_value("birth", "date");
	 my $val  = $record->get_value("birth date");
	 my $val  = $record->get_value(["birth", 2], "date");

       Retrieve a record's value.

       If arguments are specified, record() is first called with those arguments, and the values of those records are returned.

   add
	 my $rec  = $record->add("birth date", "1 Jan 2000");

       Add a new record.

       Add a new record ($rec) as a sub-item of $record.  Set its value to the last argument given.  The first arguments may be specified as for
       record().  A new record will always be created for the last argument, and for any arguments for which the count is explicitly set to zero.

       If the new record does not take a value then do not supply one.	This does mean that you cannot use the function with many arguments if the
       last one is a scalar, but not a value.  In this case either specify the last argument as ["arg", 0], or add undef as the last argument.

   set
	 my $rec  = $record->set("birth date", "2 Jan 2000");

       Set the value of a record.

       This is the same as add(), with the exception that a new record is not created for the last argument.

   parse
	 $self->parse($record, $grammar);

       Parse a Gedcom record.

       Match a Gedcom::Record against a Gedcom::Grammar.  Warn of any mismatches, and associate the Gedcom::Grammar with the Gedcom::Record as
       $record->{grammar}.  Do this recursively.

   collect_xrefs
	 $record->collect_xrefs($callback);

       Recursively collect all the xrefs.  Called by Gedcom::collect_xrefs.  $callback is not used yet.

   resolve_xref
	 my $xref = $record->resolve_xref($value);

       See Gedcom::resolve_xrefs()

   resolve
	 my @famc = $record->resolve $record->tag_value("FAMC");

       For each argument, either return it or, if it an xref, return the referenced record.

   resolve_xrefs
	 $record->resolve_xrefs($callback);

       See Gedcom::resolve_xrefs()

   unresolve_xrefs
	 $record->unresolve_xrefs($callback);

       See Gedcom::unresolve_xrefs()

   validate_semantics
	 return 0 unless $record->validate_semantics;

       Validate the semantics of the Gedcom::Record.  This performs a number of consistency checks, but could do even more.

       Returns true iff the Record is valid.

   normalise_dates
	 $record->normalise_dates($format);

       Change the format of all dates in the record.

       See the documentation for Gedcom::normalise_dates

   renumber
	 $record->renumber($args);

       Renumber the record.

       See Gedcom::renumber().

   child_value
       NOTE - This function is deprecated - use tag_value instead.

	 my $child = $record->child_value("NAME");

   child_values
       NOTE - This function is deprecated - use tag_value instead.

	 my @children = $record->child_values("CHIL");

   summary
	 print $record->summary, "
";

       Return a line of text summarising the record.

   delete_record
	 $record->delete_record($sub_record);

       Delete the specified sub-record from the record.

   Access functions
       All the Gedcom tag names can be used as function names.	Depending on the context in which they are called, the functions return either an
       array of the specified sub-items, or the first specified sub-item.

       The descriptions of the tags, with spaces replaced by underscores, can also be used as function names.  The function names can be of
       either, or mixed case.  Unless you use the tag name, in either case, or the description in lower case, the function will not be pre-
       declared and you will need to qualify it or "use subs".
