DOM(3) User Contributed Perl Documentation DOM(3)NAMEXML::Generator::DOM - XML::Generator subclass for producing DOM trees
instead of strings.
SYNOPSIS
use XML::Generator::DOM;
my $dg = XML::Generator::DOM->new();
my $doc = $dg->xml($dg->xmlcmnt("Test document."),
$dg->foo({'baz' => 'bam'}, 42));
print $doc->toString;
yields:
<?xml version="1.0" standalone="yes"?>
<!--Test document-->
<foo baz="bam">42</foo>
DESCRIPTIONXML::Generator::DOM subclasses XML::Generator in order to produce DOM
trees instead of strings (see XML::Generator and XML::DOM). This mod-
ule is still experimental and its semantics might change.
Essentially, tag methods return XML::DOM::DocumentFragment objects,
constructed either from a DOM document passed into the constructor or a
default document that XML::Generator::DOM will automatically construct.
Calling the xml() method will return this automatically constructed
document and cause a fresh one to be constructed for future tag method
calls. If you passed in your own document, you may not call the xml()
method.
Below, we just note the remaining differences in semantics between
XML::Generator methods and XML::Generator::DOM methods.
CONSTRUCTOR
These configuration options are accepted but have no effect on the
semantics of the returned object: escape, pretty, conformance and
empty.
TAG METHODS
Subsequently, tag method semantics are somewhat different for this mod-
ule compared to XML::Generator. The primary difference is that tag
method return XML::DOM::DocumentFragment objects. Namespace and
attribute processing remains the same, but remaining arguments to tag
methods must either be text or other XML::DOM::DocumentFragment
objects. No escape processing, syntax checking, or output control is
done; this is all left up to XML::DOM.
SPECIAL TAGS
All special tags are available by default with XML::Generator::DOM; you
don't need to use 'conformance' => 'strict'.
xmlpi(@args)
Arguments will simply be concatenated and passed as the data to the
XML::DOM::ProcessingInstruction object that is returned.
xmlcmnt
Escaping of '--' is done by XML::DOM::Comment, which replaces both
hyphens with '-'. An XML::DOM::Comment object is returned.
xmldecl
Returns an XML::DOM::XMLDecl object. Respects 'version', 'encoding'
and 'dtd' settings in the object.
xmldecl
Returns an XML::DOM::DocumentType object.
xmlcdata
Returns an XML::DOM::CDATASection object.
xml
As described above, xml() can only be used when dom_document was not
set in the object. The automatically created document will have its
XML Declaration set and the arguments to xml() will be appended to it.
Then a new DOM document is automatically generated and the old one is
returned. This is the only way to get a DOM document from this module.
