57 | =head1 SYNOPSIS
|
---|
58 |
|
---|
59 | use XML::Parser;
|
---|
60 | my $p = XML::Parser->new(Style => 'Objects', Pkg => 'MyNode');
|
---|
61 | my $tree = $p->parsefile('foo.xml');

63 | =head1 DESCRIPTION
|
---|
64 |
|
---|
65 | This module implements XML::Parser's Objects style parser.
|
---|
66 |
|
---|
67 | This is similar to the Tree style, except that a hash object is created for
|
---|
68 | each element. The corresponding object will be in the class whose name
|
---|
69 | is created by appending "::" and the element name to the package set with
|
---|
70 | the Pkg option. Non-markup text will be in the ::Characters class. The
|
---|
71 | contents of the corresponding object will be in an anonymous array that
|
---|
72 | is the value of the Kids property for that object.
