What are the potential pitfalls of using simple_xml to search through a large XML file in PHP?

Using simplexml_load_file() to search through a large XML file in PHP can be inefficient and slow, especially for large files. It can also consume a lot of memory when loading the entire XML file into memory. To address this issue, consider using XMLReader or XPath to efficiently navigate through the XML file without loading the entire document into memory. 

$reader = new XMLReader();
$reader->open('large.xml');

while ($reader->read()) {
    // Search for specific elements or attributes using XMLReader
    // Perform actions based on the search results
}

$reader->close();
