B4P Reference

Introduction

With the procedure table load(), B4P loads tables defined inside HTML files. Only the actual contents and without any tags and formatting features will be loaded. The table must be in the syntax
<table>, <tr> optionally <th> and </th>, </td> and </td>, , </tr>. Script files and nested tables inside tables will be ignored. In order to load a specific table in the HTML file, use the 4th function parameter in the function table load() to specify a text pattern.

       echo(new line, "Look up some Roman emperors:" );

       file download overwrite( "en.wikipedia.org/wiki/List_of_Roman_emperors", Emperors.html );

       table load( emperors, Emperors.html, HTML, 'id="Principate' );

       table keep columns ( emperors, 1 ); // Name only Otherwise the table is too wide

       table list( emperors );

       file delete silently( Emperors.html );

Look up some Roman emperors:
    0 :  Name[f]                                             
    1 : Augustus Caesar Augustus                             
    2 : Tiberius Tiberius Caesar Augustus                    
    3 : Caligula Gaius Caesar Augustus Germanicus
