嗨我在PHP中生成一个xml文件,但收到错误

XML解析错误:XML或文本声明不在实体的开头

我的代码是---

<?php require_once('../../settings.php');
header("Content-type:text/xml");
$dom=new DOMDocument('1.0'); 
$dom->formatOutput = true;
$id=(int)$_GET['imageid'];
 $query="select * from tbl_image_gallery where imageId='$id' ORDER BY gallId DESC ";
$select=mysql_query($query);
$content = $dom->appendChild($dom->createElement('content'));
while($res=mysql_fetch_array($select))
{
    $image = $content->appendChild($dom->createElement('image'));
    $small_image_path = $image->appendChild($dom->createElement('small_image_path'));
    $small_image_path->appendChild($dom->createTextNode("image_gallery/load/images/small/".$res['image'])); 
    $big_image_path = $image->appendChild($dom->createElement('big_image_path'));
    $big_image_path->appendChild($dom->createTextNode("image_gallery/load/images/big/".$res['image']));
    $description = $image->appendChild($dom->createElement('description'));
    $description->appendChild($dom->createCDATASection($res['description']));
 }   
echo $test1 = $dom->saveXML(); 
?>

在google上搜索之后我发现它与之前的空间有关

我删除空间但没有得到预期的结果.
