What are common issues when parsing XML files in PHP, especially when the XML code is not properly formatted?

When parsing XML files in PHP, common issues arise when the XML code is not properly formatted. This can lead to parsing errors or unexpected behavior in the code. To solve this issue, it is important to validate the XML file before parsing it, and handle any potential errors or exceptions that may occur during the parsing process. 

// Load the XML file and validate it before parsing
$xml = file_get_contents('example.xml');
$doc = new DOMDocument();
$doc->loadXML($xml);

// Check if the XML file is valid
if ($doc->validate()) {
    // Proceed with parsing the XML file
    // Your parsing code here
} else {
    // Handle validation errors
    echo "XML file is not valid.";
}
