       Bio::OntologyIO::Handlers::BaseSAXHandler - base	class for SAX Handlers

       See description.

       This module is an abstract module, serving as the base of any SAX
       Handler implementation. It tries	to offer the framework that SAX
       handlers	generally need,	such as	tag_stack, char_store, etc.

       In the implementation handler, you can take advantage of	this based
       module by the following suggestions.

       1) In start_element,

	sub start_element {
	    my $self=shift;
	    my $tag=$_[0]->{Name};
	    my %args=%{$_[0]->{Attributes}};
	    # Your code	here.

	    # Before you conclude the method, write these 2 line.

       2) In end_element,

	sub end_element	{
	    my $self=shift;
	    my $tag=shift->{Name};
	    # Your code	here.

	    # Before you conclude the method, write these 2 lines.

       3) In characters, or any	other methods where you	may use	the tag	stack
       or count

	sub characters {
	    my $self=shift;
	    my $text=shift->{Data};

	    $self->_chars_hash->{$self->_top_tag} .= $text;

	$count = $self->_visited_count('myTag');
	$tag = $self->_top_tag;

   Mailing Lists
       User feedback is	an integral part of the	evolution of this and other
       Bioperl modules.	Send your comments and suggestions preferably to one
       of the Bioperl mailing lists.

       Your participation is much appreciated.			- General discussion	- About	the mailing lists

       Please direct usage questions or	support	issues to the mailing list:

       rather than to the module maintainer directly. Many experienced and
       reponsive experts will be able look at the problem and quickly address
       it. Please include a thorough description of the	problem	with code and
       data examples if	at all possible.

   Reporting Bugs
       Report bugs to the Bioperl bug tracking system to help us keep track
       the bugs	and their resolution.  Bug reports can be submitted via	the
