NAME

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

SYNOPSIS

10         use HTML::ElementGlob;
11         $element_a = new HTML::Element 'font', color => 'red';
12         $element_b = new HTML::Element 'font', color => 'blue';
13         $element_a->push_content('red');
14         $element_b->push_content('blue');
15
16         $p = new HTML::Element 'p';
17         $p->push_content($element_a, ' and ', $element_b, ' boo hoo hoo');
18
19         # Tag type of the glob is not really relevant unless
20         # you plan on seeing the glob as_HTML()
21         $eglob = new HTML::ElementGlob 'p';
22         $eglob->glob_push_content($element_a, $element_b);
23         # Alter both elements at once
24         $eglob->attr(size => 5);
25
26         # They still belong to their original parent
27         print $p->as_HTML;

DESCRIPTION

30       HTML::ElementGlob is a managing object for multiple HTML::Element(3)
31       style elements.  The children of the glob element retain their original
32       parental elements and have no knowledge of the glob that manipulates
33       them.  All methods that do not start with 'glob_' will be passed,
34       sequentially, to all elements contained within the glob element.
35       Methods starting with 'glob_' will operate on the glob itself, rather
36       than being passed to its foster children.
37
38       For example, $eglob->attr(size => 3) will invoke attr(size => 3) on all
39       children contained by $eglob.  $eglob->glob_attr(size => 3), on the
40       other hand, will set the attr attribute on the glob itself.
41
42       The tag type passed to HTML::Element::Glob is largely irrrelevant as
43       far as how methods are passed to children.  However, if you choose to
44       invoke $eglob->as_HTML(), you might want to pick a tag that would
45       sensibly contain the globbed children for debugging or display
46       purposes.
47
48       The 'glob_*' methods that operate on the glob itself are limited to
49       those available in an HTML::Element(3).  All other methods get passed
50       blindly to the globbed children, which can be enhanced elements with
51       arbitrary methods, such as HTML::ElementSuper(3).
52
53       Element globs can contain other element globs.  In such cases, the
54       plain methods will cascade down to the leaf children.  'glob_*'
55       methods, of course, will not be propogated to children globs.  You will
56       have to rely on glob_content() to access those glob children and access
57       their 'glob_*' methods directly.
