In what scenarios would using a parser like XMLReader be more beneficial than using DOM-XPath for XML parsing in PHP?

XMLReader is more beneficial than DOM-XPath for XML parsing in PHP when dealing with large XML files or streams, as XMLReader does not load the entire document into memory. This can lead to better performance and reduced memory usage when processing large XML files. Additionally, XMLReader is more suitable for sequential access to XML data, while DOM-XPath is better for random access. 

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

while ($reader->read()) {
    // process each node in the XML file
}

$reader->close();
