NAME

       HTML::ElementGlob - Perl extension for managing HTML::Element based objects as a single object.

SYNOPSIS

	 use HTML::ElementGlob;
	 $element_a = new HTML::Element 'font', color => 'red';
	 $element_b = new HTML::Element 'font', color => 'blue';
	 $element_a->push_content('red');
	 $element_b->push_content('blue');

	 $p = new HTML::Element 'p';
	 $p->push_content($element_a, ' and ', $element_b, ' boo hoo hoo');

	 # Tag type of the glob is not really relevant unless
	 # you plan on seeing the glob as_HTML()
	 $eglob = new HTML::ElementGlob 'p';
	 $eglob->glob_push_content($element_a, $element_b);
	 # Alter both elements at once
	 $eglob->attr(size => 5);

	 # They still belong to their original parent
	 print $p->as_HTML;

DESCRIPTION

       HTML::ElementGlob is a managing object for multiple HTML::Element(3) style elements.  The children of the glob element retain their
       original parental elements and have no knowledge of the glob that manipulates them.  All methods that do not start with 'glob_' will be
       passed, sequentially, to all elements contained within the glob element.  Methods starting with 'glob_' will operate on the glob itself,
       rather than being passed to its foster children.

       For example, $eglob->attr(size => 3) will invoke attr(size => 3) on all children contained by $eglob.  $eglob->glob_attr(size => 3), on the
       other hand, will set the attr attribute on the glob itself.

       The tag type passed to HTML::Element::Glob is largely irrrelevant as far as how methods are passed to children.	However, if you choose to
       invoke $eglob->as_HTML(), you might want to pick a tag that would sensibly contain the globbed children for debugging or display purposes.

       The 'glob_*' methods that operate on the glob itself are limited to those available in an HTML::Element(3).  All other methods get passed
       blindly to the globbed children, which can be enhanced elements with arbitrary methods, such as HTML::ElementSuper(3).

       Element globs can contain other element globs.  In such cases, the plain methods will cascade down to the leaf children.  'glob_*' methods,
       of course, will not be propogated to children globs.  You will have to rely on glob_content() to access those glob children and access
       their 'glob_*' methods directly.

REQUIRES

       HTML::ElementSuper(3)
