What are some common pitfalls to avoid when using PHP's xml_parse_into_struct function for parsing XML data?

One common pitfall to avoid when using PHP's xml_parse_into_struct function is not properly checking for errors that may occur during parsing. To ensure robust error handling, always check the return value of xml_parse_into_struct to detect any parsing errors. Additionally, make sure to properly handle the structure array returned by the function to extract the desired data from the XML. 

$xml = '<root><item>Item 1</item><item>Item 2</item></root>';
$parser = xml_parser_create();
if (!xml_parse_into_struct($parser, $xml, $structure, $index)) {
    die('Error parsing XML');
}
xml_parser_free($parser);

// Process the structure array to extract data
foreach ($structure as $element) {
    if ($element['tag'] == 'ITEM') {
        echo $element['value'] . "\n";
    }
}
