What are the common challenges faced when reading XML files using PHP scripts?

One common challenge when reading XML files using PHP scripts is handling large XML files that may exceed memory limits. To solve this, you can use XMLReader, a lightweight and efficient parser that allows you to read XML files node by node without loading the entire file into memory. 

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

while ($reader->read()) {
    // process each node here
}

$reader->close();
