How can PHP beginners improve their understanding of XML parsing and manipulation, based on the experiences shared in the forum thread?

Issue: PHP beginners can improve their understanding of XML parsing and manipulation by practicing with simple XML files and gradually increasing the complexity of the XML structures they work with. They can also refer to online tutorials, documentation, and forums to learn about different PHP functions and methods for XML manipulation. Code snippet:

$xmlString = '<?xml version="1.0" encoding="UTF-8"?>
<bookstore>
  <book category="fiction">
    <title>Harry Potter</title>
    <author>J.K. Rowling</author>
  </book>
  <book category="non-fiction">
    <title>PHP for Beginners</title>
    <author>John Smith</author>
  </book>
</bookstore>';

$xml = simplexml_load_string($xmlString);

foreach ($xml->book as $book) {
    echo "Title: " . $book->title . "<br>";
    echo "Author: " . $book->author . "<br>";
    echo "<br>";
}
