XML::Compile::Util - Utility routines for XML::Compile components

 XML::Compile::Util
   is a Exporter

 use XML::Compile::Util;
 my $node_type = pack_type $ns, $localname;
 my ($ns, $localname) = unpack_type $node_type;

The functions provided by this package are used by various XML::Compile components, which on their own may be unrelated.

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

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.

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.
