Fsdb::Filter::html_table_to_db

NAME

html_table_to_db - convert HTML tables into fsdb

SYNOPSIS

html_table_to_db <source.html >dest.fsdb

DESCRIPTION

Converts a HTML table to Fsdb format.

The input is an HTML table (not fsdb). Column names are taken from "TH" elements, or defined as "column0" through "columnN" if no such elements appear.

The output is two-space-separated fsdb. (Someday more general field separators should be supported.) Fsdb fields are normalized version of the html file: multiple spaces are compressed to one.

This module also supports the standard fsdb options:

-i or --input InputSource

Read from InputSource, typically a file name, or "-" for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

-o or --output OutputDestination

Write to OutputDestination, typically a file name, or "-" for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

--autorun or --noautorun

By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The "--(no)autorun" option controls that behavior within Perl.
