Net::DNS::RR::TXT(3)					User Contributed Perl Documentation				      Net::DNS::RR::TXT(3)

NAME
Net::DNS::RR::TXT - DNS TXT resource record SYNOPSIS
use Net::DNS; $rr = new Net::DNS::RR( 'name TXT txtdata ...' ); $rr = new Net::DNS::RR( name => 'name', type => 'TXT', txtdata => 'single text string' ); $rr = new Net::DNS::RR( name => 'name', type => 'TXT', txtdata => [ 'multiple', 'strings', ... ] ); use utf8; $rr = new Net::DNS::RR( 'jp TXT XXXXXXXXXXXX' ); DESCRIPTION
Class for DNS Text (TXT) resource records. METHODS
The available methods are those inherited from the base class augmented by the type-specific methods defined in this package. Use of undocumented package features or direct access to internal data structures is discouraged and could result in program termination or other unpredictable behaviour. txtdata $string = $rr->txtdata; @list = $rr->txtdata; $rr->txtdata( @list ); When invoked in scalar context, txtdata() returns the descriptive text as a single string, regardless of the number of elements. In a list context, txtdata() returns a list of the text elements. COPYRIGHT
