CakePHP的XML核心String類不能被解析爲XML

Question

我試過下面的查詢和使用Cake的核心XML類，但我得到的字符串不能被解析爲XML錯誤...

$output = $this->Job->query(" 
      SELECT job.id, job.title, organisation.name, jobsboard.name 
      FROM job 
      LEFT JOIN portfolio_job_category pjc ON pjc.job_id = job.id 
      LEFT JOIN category c ON c.id = pjc.category_id 
      LEFT JOIN organisation ON organisation.id = job.organisation_id 
      LEFT JOIN portfolio jobsboard ON jobsboard.id = pjc.portfolio_id 
      WHERE job.end_date >= DATE(NOW()) 
      AND pjc.portfolio_id = $portfolio 
      ORDER BY c.id DESC 
      "); 
$jobs['jobs_feed'] = $output; 
$jobs = Xml::fromArray($jobs); 
$jobs = $jobs->asXML(); 

下面是我的從模型的自定義查詢中輸出數組。

Array 
(
    [0] => Array 
     (
      [job] => Array 
       (
        [id] => 38459 
        [title] => UTS: Engineering Research Scholarships in Petroleum Remediation 
       ) 

      [organisation] => Array 
       (
        [name] => University of Technology Sydney 
       ) 

      [jobsboard] => Array 
       (
        [name] => Research Jobs 
       ) 

     ) 

    [1] => Array 
     (
      [job] => Array 
       (
        [id] => 44144 
        [title] => Associate Lecturer - Clinical Exercise Physiology 
       ) 

      [organisation] => Array 
       (
        [name] => James Cook University 
       ) 

      [jobsboard] => Array 
       (
        [name] => Research Jobs 
       ) 

     ) 
) 

有什麼我可以做的，以解決這個問題？

Answer 1

的Xml需要根節點：

變化：

$jobs = Xml::fromArray($jobs); 

到：

$jobs = Xml::fromArray(array('jobs' => $jobs));
