(PHP Extension) HTML Table to CSV

Demonstrates a method for converting an HTML table to a CSV file.

Note: This example requires Chilkat v9.5.0.77 or greater.

Chilkat PHP Downloads

PHP Extension for Windows, Linux, MacOS,
Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// First download the HTML containing the table
$http = new CkHttp();
$bdHtml = new CkBinData();

$success = $http->QuickGetBd('https://example-code.com/data/etf_table.html',$bdHtml);
if ($success != true) {
    print $http->lastErrorText() . "\n";
    exit;
}

// Convert to XML.
$htx = new CkHtmlToXml();
$htx->SetHtmlBd($bdHtml);

$sbXml = new CkStringBuilder();
$htx->ToXmlSb($sbXml);

$xml = new CkXml();
$xml->LoadSb($sbXml,true);

// Remove attributes and sub-trees we don't need.
// (In other words, we're getting rid of clutter...)
$numRemoved = $xml->PruneTag('thead');
$numRemoved = $xml->PruneAttribute('style');
$numRemoved = $xml->PruneAttribute('class');

// Scrub the element and attribute content.
$xml->Scrub('ContentTrimEnds,ContentTrimInside,AttrTrimEnds,AttrTrimInside');

// Let's see what we have...
print $xml->getXml() . "\n";

// We have the following XML.
// Copy this XML into the online tool at Generate Parsing Code from XML
// as a starting point for accessing the data..

// <?xml version="1.0" encoding="utf-8"?>
