What are the common challenges faced when parsing HTML format emails in PHP?

One common challenge when parsing HTML format emails in PHP is correctly handling and extracting the desired content from the HTML markup, which can be complex and nested. To solve this, you can use PHP libraries like DOMDocument or Simple HTML DOM Parser to parse the HTML structure and extract the necessary information. 

// Example using DOMDocument to parse HTML format email
$html = '<html><body><h1>Hello World!</h1></body></html>';

$dom = new DOMDocument();
$dom->loadHTML($html);

$heading = $dom->getElementsByTagName('h1')->item(0)->nodeValue;

echo $heading; // Output: Hello World!
