Are there specific tools or validators that can help troubleshoot PHP-generated XML feeds with link parsing problems?

When troubleshooting PHP-generated XML feeds with link parsing problems, one approach is to use XML validators such as XMLLint or online tools like W3C Markup Validation Service to check for syntax errors or invalid characters in the XML feed. Additionally, you can use PHP libraries like SimpleXMLElement or DOMDocument to parse and manipulate the XML data to ensure that links are correctly formatted. 

// Example PHP code snippet using SimpleXMLElement to parse XML feed and extract links
$xml = file_get_contents('example.xml');
$xmlObj = new SimpleXMLElement($xml);

foreach ($xmlObj->xpath('//link') as $link) {
    echo (string) $link . "\n";
}
