NAME¶
XML::Compile::Util - Utility routines for XML::Compile componentsINHERITANCE¶
XML::Compile::Util is a Exporter
SYNOPSIS¶
use XML::Compile::Util; my $node_type = pack_type $ns, $localname; my ($ns, $localname) = unpack_type $node_type;
DESCRIPTION¶
The functions provided by this package are used by various XML::Compile components, which on their own may be unrelated.FUNCTIONS¶
Constants¶
The following URIs are exported as constants, to avoid typing in the same long URIs each time again: XMLNS, SCHEMA1999, SCHEMA2000, SCHEMA2001, and SCHEMA2001i.Packing¶
- pack_id($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.
