How can PHP beginners effectively debug issues related to XML parsing and node attribute access in their code?

To effectively debug XML parsing and node attribute access issues in PHP, beginners can use functions like `simplexml_load_string()` to parse XML data and `attributes()` to access node attributes. To troubleshoot, beginners can use `var_dump()` or `print_r()` to inspect the structure of the XML data and ensure they are accessing the correct nodes and attributes. 

$xml = '<bookstore>
  <book category="fiction">
    <title>Harry Potter</title>
    <author>J.K. Rowling</author>
  </book>
</bookstore>';

$books = simplexml_load_string($xml);

foreach ($books->book as $book) {
    $category = $book->attributes()['category'];
    $title = $book->title;
    $author = $book->author;
    
    echo "Category: $category, Title: $title, Author: $author\n";
}
