SYNOPSIS
my $h = SomeHandler->new;
my $f = XML::Filter::BufferText->new( Handler => $h );
my $p = SomeParser->new( Handler => $f );
$p->parse;
DESCRIPTION
This is a very simple filter. One common cause of grief (and programmer
error) is that XML parsers aren't required to provide character events
in one chunk. They can, but are not forced to, and most don't. This
filter does the trivial but oft-repeated task of putting all characters
into a single event.
Note that this won't help you cases such as:
<foo> blah <!-- comment --> phubar </foo>
In the above case, given the interleaving comment, there will be two
"character()" events. This may be worked around in the future if there
is demand for it.
An interesting way to use this filter, instead of telling users to use
it, is to return it from your handler's constructor, already configured
and all. That'll make the buffering totally transparent to them
("XML::SAX::Writer" does that).
