What are the potential challenges or limitations when trying to convert HTML to Word XML on a web server running Linux?

One potential challenge when converting HTML to Word XML on a web server running Linux is the lack of support for Microsoft Word-specific formatting and features. To overcome this limitation, you can use a library like PHPWord to generate Word documents with basic styling and content.

<?php
require_once 'vendor/autoload.php';

$html = '<h1>Hello World!</h1><p>This is a sample paragraph.</p>';

// Create a new Word document
$phpWord = new \PhpOffice\PhpWord\PhpWord();

// Add HTML content to the document
$htmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'HTML');
$htmlWriter->write($html);

// Save the document as Word XML
$wordXMLWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2003ML');
$wordXMLWriter->save('output.docx');
?>
