NAME¶
XML::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.')));
