Constants

The following URIs are exported as constants, to avoid typing in the same long URIs each time again: XMLNS, SCHEMA1999, SCHEMA2000, SCHEMA2001, and SCHEMA2001i.

Packing

pack_id($ns, $id)

Translates the two arguments into one compact string representation of the node id.

example:

 print pack_id 'http://my-ns', 'my-id';
 # shows:  http://my-ns#my-id

pack_type( [$ns], $localname )

Translates the arguments into one compact string representation of the node type. When the $ns is not present, "undef", or an empty string, then no namespace is presumed, and no curly braces part made.

example:

 print pack_type 'http://my-ns', 'my-type';
 # shows:  {http://my-ns}my-type 
 print pack_type 'my-type';
 print pack_type undef, 'my-type';
 print pack_type '', 'my-type';
 # all three show:   my-type

unpack_id($string)

Returns a LIST of two elements: the name-space and the id, as included in the $string. That $string must be compatible with the result of pack_id().

unpack_type($string)

Returns a LIST of two elements: the name-space and the localname, as included in the $string. That $string must be compatible with the result of pack_type(). When no name-space is present, an empty string is used.

Other

add_duration( $duration, [$time] )

[1.44] Add the $duration to the $time (defaults to 'now') This is an expensive operation: in many cases the duration2secs() produces useful results as well.

example:

   my $now      = time;
   my $deadline = add_duration 'P1M', $now;  # deadline in 1 month

duration2secs($duration)

[1.44] Translate any format into seconds. This is an example of a valid duration: "-PT1M30.5S" Average month and year lengths are used. If you need more precise calculations, then use add_duration().

even_elements(LIST)

Returns the even-numbered elements from the LIST.

odd_elements(LIST)

Returns the odd-numbered elements from the LIST.

type_of_node($node)

Translate an XML::LibXML::Node into a packed type.
