What are the common pitfalls when iterating through XML nodes in PHP for CSV conversion?

Common pitfalls when iterating through XML nodes in PHP for CSV conversion include not handling nested nodes properly, not accounting for different tag structures, and not properly escaping special characters in the data. To solve these issues, it's important to recursively iterate through all nodes, handle nested nodes appropriately, and escape special characters before writing to the CSV file. 

// Function to recursively iterate through XML nodes and convert to CSV
function xmlToCsv($xml, $csvFile) {
    $file = fopen($csvFile, 'w');
    
    foreach ($xml->children() as $node) {
        $data = [];
        
        foreach ($node->children() as $child) {
            $data[] = $child->nodeValue;
        }
        
        fputcsv($file, $data);
        
        if ($node->count() > 0) {
            xmlToCsv($node, $csvFile);
        }
    }
    
    fclose($file);
}

// Usage example
$xml = simplexml_load_file('data.xml');
xmlToCsv($xml, 'output.csv');
