NAME
NET::LDAP::DSML -- A DSML Writer for Net::LDAP
SYNOPSIS
For a directory entry;
use Net::LDAP;
use Net::LDAP::DSML;
use IO::File;
my $server = "localhost";
my $file = "testdsml.xml";
my $ldap = Net::LDAP->new($server);
$ldap->bind();
#
# For file i/o
#
my $file = "testdsml.xml";
my $io = IO::File->new($file,"w") or die ("failed to open $file as filehandle.$!\n");
my $dsml = Net::LDAP::DSML->new(output => $io, pretty_print => 1 )
or die ("DSML object creation problem using an output file.\n");
# OR
#
# For file i/o
#
open (IO,">$file") or die("failed to open $file.$!");
my $dsml = Net::LDAP::DSML->new(output => *IO, pretty_print => 1)
or die ("DSML object creation problem using an output file.\n");
# OR
#
# For array usage.
# Pass a reference to an array.
#
my @data = ();
$dsml = Net::LDAP::DSML->new(output => \@data, pretty_print => 1)
or die ("DSML object cration problem using an output array.\n");
my $mesg = $ldap->search(
base => 'o=airius.com',
scope => 'sub',
filter => 'ou=accounting',
callback => sub {
my ($mesg,$entry) =@_;
$dsml->write_entry($entry)
if (ref $entry eq 'Net::LDAP::Entry');
}
);
die ("search failed with ",$mesg->code(),"\n") if $mesg->code();
For directory schema;
A file or array can be used for output, in the following example
only an array will be used.
my $schema = $ldap->schema();
my @data = ();
my $dsml = Net::LDAP::DSML->new(output => \@data, pretty_print => 1 )
or die ("DSML object creation problem using an output array.\n");
$dsml->write_schema($schema);
print "Finished printing DSML\n";
DESCRIPTION
Directory Service Markup Language (DSML) is the XML standard for
representing directory service information in XML.
At the moment this module only writes DSML entry and schema entities.
Reading DSML entities is a future project.
Eventually this module will be a full level 2 consumer and producer
enabling you to give you full DSML conformance. Currently this module
has the ability to be a level 2 producer. The user must understand the
his/her directory server will determine the consumer and producer level
they can achieve.
To determine conformance, it is useful to divide DSML documents into
four types:
1.Documents containing no directory schema nor any references to
an external schema.
2.Documents containing no directory schema but containing at
least one reference to an external schema.
3.Documents containing only a directory schema.
4.Documents containing both a directory schema and entries.
A producer of DSML must be able to produce documents of type 1. A
producer of DSML may, in addition, be able to produce documents of
types 2 thru 4.
A producer that can produce documents of type 1 is said to be a level 1
producer. A producer than can produce documents of all four types is
said to be a level 2 producer.
CALLBACKS
The module uses callbacks to improve performance (at least the
appearance of improving performance ;) and to reduce the amount of
memory required to parse large DSML files. Every time a single entry or
schema is processed we pass the Net::LDAP object (either an Entry or
Schema object) to the callback routine.
CONSTRUCTOR
new ()
Creates a new Net::LDAP::DSML object. There are 2 options to this
method.
"output" is a reference to either a file handle that has already
been opened or to an array.
"pretty_print" is an option to print a new line at the end of each
element sequence. It makes the reading of the XML output easier
for a human.
Example
my $dsml = Net::LDAP::DSML->new();
Prints xml data to standard out.
my $dsml = Net::LDAP::DSML->new(output => \@array);
my $dsml = Net::LDAP::DSML->new(output => *FILE);
Prints xml data to a file or array.
my $dsml = Net::LDAP::DSML->new(output => \@array, pretty_print => 1);
my $dsml = Net::LDAP::DSML->new(output => *FILE, pretty_print => 1);
Prints xml data to a file or array in pretty print style.
METHODS
start_dsml ()
Start a DSML file.
end_dsml ()
End a DSML file.
write_entry ( ENTRY )
Entry is a Net::LDAP::Entry object. The write method will parse the
LDAP data in the Entry object and put it into DSML XML format.
Example
my $entry = $mesg->entry();
$dsml->write_entry($entry);
write_schema ( SCHEMA )
Schema is a Net::LDAP::Schema object. The write_schema method will
parse the LDAP data in the Schema object and put it into DSML XML
format.
Example
my $schema = $ldap->schema();
$dsml->write_schema($schema);
