What are some common mistakes to avoid when using PHP to manipulate XML content, especially in terms of syntax errors or incorrect method calls?

One common mistake to avoid when manipulating XML content in PHP is using incorrect method calls or syntax errors. To prevent this, always double-check the method names and parameters when working with XML functions in PHP. Additionally, ensure that your XML content is well-formed to avoid parsing errors. 

// Incorrect method call example
$xml = new SimpleXMLElement('<root><item>Value</item></root>');
$value = $xml->getElementByTagName('item'); // Incorrect method name

// Correct method call
$xml = new SimpleXMLElement('<root><item>Value</item></root>');
$value = $xml->getElementsByTagName('item');
