我在CakePHP中輸出XML。但是，當我把我的XML爲驗證我得到這個錯誤：不允許處理指令匹配「[xX] [mM] [lL]」
The processing instruction target matching "[xX][mM][lL]" is not allowed.
我使用正確的XML佈局<?php echo $this->Xml->header(); ?>頂部則<?php echo $content_for_layout; ?>
我的結果是：
<?xml version="1.0" encoding="UTF-8" ?><response type='' outcome='true' message='Login successful!'>

這有什麼不對嗎？
你是否檢查XML是否在開始時沒有任何空格而生成？ – elboletaire
