.SH DESCRIPTION
.IX Header "DESCRIPTION"
HTML::ElementGlob is a managing object for multiple
\&\fBHTML::Element\fR\|(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 \*(Aqglob_\*(Aq will be passed, sequentially, to
all elements contained within the glob element.  Methods
starting with \*(Aqglob_\*(Aq will operate on the glob itself, rather
than being passed to its foster children.
.PP
For example, \f(CW$eglob\fR\->attr(size => 3) will invoke attr(size => 3) on
all children contained by \f(CW$eglob\fR.  \f(CW$eglob\fR\->glob_attr(size => 3), on
the other hand, will set the attr attribute on the glob itself.
.PP
The tag type passed to HTML::Element::Glob is largely
irrrelevant as far as how methods are passed to children.  However,
if you choose to invoke \f(CW$eglob\fR\->\fBas_HTML()\fR, you might want to pick
a tag that would sensibly contain the globbed children for debugging
or display purposes.
.PP
The \*(Aqglob_*\*(Aq methods that operate on the glob itself are limited
to those available in an \fBHTML::Element\fR\|(3).  All other methods get
passed blindly to the globbed children, which can be enhanced elements
with arbitrary methods, such as \fBHTML::ElementSuper\fR\|(3).
.PP
Element globs can contain other element globs.  In such cases, the
plain methods will cascade down to the leaf children.  \*(Aqglob_*\*(Aq methods,
of course, will not be propogated to children globs.  You will
have to rely on \fBglob_content()\fR to access those glob children and
access their \*(Aqglob_*\*(Aq methods directly.
