HTML::TableParser::Table - support class for HTML::TableParser
version 0.43
This class is used to keep track of information related to a table and
to create the information passed back to the user callbacks. It is in
charge of marshalling the massaged header and row data to the user
callbacks.
An instance is created when the controlling TableParser class finds a
<table tag. The object is given an id based upon which table it is
to work on. Its methods are invoked from the TableParser callbacks
when they run across an appropriate tag (tr, th, td). The
object is destroyed when the matching /table tag is found.
Since tables may be nested, multiple HTML::TableParser::Table
objects may exist simultaneously. HTML::TableParser uses two
pieces of information held by this class -- ids and process. The
first is an array of table ids, one element per level of table
nesting. The second is a flag indicating whether this table is being
processed (i.e. it matches a requested table) or being ignored. Since
HTML::TableParser uses the ids information from an existing table
to initialize a new table, it first creates an empty sentinel (place
holder) table (by calling the HTML::TableParser::Table constructor
with no arguments).
The class handles missing /tr, /td, and /th tags. As such
(especially when handling multi-row headers) user callbacks may
be slightly delayed (and data cached). It also handles rows
with overlapping columns
