XML::Grove::Factory(3)User Contributed Perl DocumentatioXML::Grove::Factory(3)NAMEXML::Grove::Factory - simplify creation of XML::Grove objects
SYNOPSIS
use XML::Grove::Factory;
### An object that creates Grove objects directly
my $gf = XML::Grove::Factory->grove_factory;
$grove = $gf->document( CONTENTS );
$element = $gf->element( $name, { ATTRIBUTES }, CONTENTS );
$pi = $gf->pi( $target, $data );
$comment = $gf->comment( $data );
### An object that creates elements by method name
my $ef = XML::Grove::Factory->element_factory();
$element = $ef->NAME( { ATTRIBUTES }, CONTENTS);
### Similar to `element_factory', but creates functions in the
### current package
XML::Grove::Factory->element_functions( PREFIX, ELEMENTS );
$element = NAME( { ATTRIBUTES }, CONTENTS );
DESCRIPTION
"XML::Grove::Factory" provides objects or defines functions that let
you simply and quickly create the most commonly used XML::Grove
objects. "XML::Grove::Factory" supports three types of object
creation. The first type is to create raw XML::Grove objects. The
second type creates XML elements by element name. The third type is
like the second, but defines local functions for you to call instead of
using an object, which might save typing in some cases.
The three types of factories can be mixed. For example, you can use
local functions for all element names that don't conflict with your own
sub names or contain special characters, and then use a
`"grove_factory()"' object for those elements that do conflict.
In the examples that follow, each example is creating an XML instance
similar to the following, assuming it's pretty printed:
<?xml version="1.0"?>
<HTML>
<HEAD>
<TITLE>Some Title</TITLE>
</HEAD>
<BODY bgcolor="#FFFFFF">
<P>A paragraph.</P>
</BODY>
</HTML>
GROVE FACTORY
$gf = XML::Grove::Factory->grove_factory()
Creates a new grove factory object that creates raw XML::Grove
objects.
$gf->document( CONTENTS );
Creates an XML::Grove::Document object. CONTENTS may contain
processing instructions, strings containing only whitespace
characters, and a single element object (but note that there is no
checking). Strings are converted to XML::Grove::Characters
objects.
$gf->element($name, CONTENTS);
$gf->element($name, { ATTRIBUTES }, CONTENTS);
Creates an XML::Grove::Element object with the name `$name'. If
the argument following `$name' is an anonymous hash, ATTRIBUTES,
then they will be copied to the elements attributes. CONTENTS will
be stored in the element's content (note that there is no validity
checking). Strings in CONTENTS are converted to
XML::Grove::Characters objects.
$gf->pi( TARGET, DATA)
$gf->pi( DATA )
Create an XML::Grove::PI object with TARGET and DATA.
$gf->comment( DATA )
Create an XML::Grove::Comment object with DATA.
GROVE FACTORY EXAMPLE
use XML::Grove::Factory;
$gf = XML::Grove::Factory->grove_factory;
$element =
$gf->element('HTML',
$gf->element('HEAD',
$gf->element('TITLE', 'Some Title')),
$gf->element('BODY', { bgcolor => '#FFFFFF' },
$gf->element('P', 'A paragraph.')));
ELEMENT FACTORY
$ef = XML::Grove::Factory->element_factory()
Creates a new element factory object for creating elements.
`"element_factory()"' objects work by creating an element for any
name used to call the object.
$ef->NAME( CONTENTS )
$ef->NAME( { ATTRIBUTES }, CONTENTS)
Creates an XML::Grove::Element object with the given NAME,
ATTRIBUTES, and CONTENTS. The hash containing ATTRIBUTES is
optional if this element doesn't need attributes. Strings in
CONTENTS are converted to XML::Grove::Characters objects.
ELEMENT FACTORY EXAMPLE
use XML::Grove::Factory;
$ef = XML::Grove::Factory->element_factory();
$element =
$ef->HTML(
$ef->HEAD(
$ef->TITLE('Some Title')),
$ef->BODY({ bgcolor => '#FFFFFF' },
$ef->P('A paragraph.')));
ELEMENT FUNCTIONS
XML::Grove::Factory->element_functions (PREFIX, ELEMENTS)
Creates functions in the current package for creating elements with
the names provided in the list ELEMENTS. PREFIX will be prepended
to every function name, or PREFIX can be an empty string ('') if
you're confident that there won't be any conflicts with functions
in your package.
NAME( CONTENTS )
NAME( { ATTRIBUTES }, CONTENTS )
PREFIXNAME( CONTENTS )
PREFIXNAME( { ATTRIBUTES }, CONTENTS )
Functions created for `"NAME"' or `"PREFIXNAME"' can be called to
create XML::Grove::Element objects with the given NAME, ATTRIBUTES,
and CONTENT. The hash containing ATTRIBUTES is optional if this
element doesn't need attributes. Strings in CONTENT are converted
to XML::Grove::Characters objects.
ELEMENT FACTORY EXAMPLE
use XML::Grove::Factory;
XML::Grove::Factory->element_functions('', qw{ HTML HEAD TITLE BODY P });
$element =
HTML(
HEAD(
TITLE('Some Title')),
BODY({ bgcolor => '#FFFFFF' },
P('A paragraph.')));
