我正在研究一些PHP,使用DOM擴展從數據庫創建XML。PHP DOM XML - 創建多個名稱空間屬性?
基本上,我需要創建一個命名空間,並添加3個屬性給它:
<NameSpaceName xmlns="uri:xxx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="uri:xxx">
完整的代碼我已經寫了低於:
include_once("includes/connect.php");
$sql = ("SELECT * FROM tableName");
$query = mysql_query($sql) or die("Error: " . mysql_error());
// create a new XML document
$doc = new DomDocument('1.0', 'UTF-8');
// create root node
$root = $doc->createElementNS('uri:xxx', 'PayerRecords');
$root = $doc->appendChild($root);
$root->setAttributeNS('http://www.w3.org/2000/xmlns/' ,'xmlns:xsi', 'http://www.w3.org/2001/XMLSchema-instance');
$root->setAttributeNS('http://www.w3.org/2000/xmlns/' ,'xsi:schemaLocation', 'uri:xxx');
// process one row at a time
while($row = mysql_fetch_assoc($query)) {
// add node for each row
$occ = $doc->createElement('Content');
$occ = $root->appendChild($occ);
// add a child node for each field
foreach ($row as $fieldname => $fieldvalue) {
$child = $doc->createElement($fieldname);
$child = $occ->appendChild($child);
$value = $doc->createTextNode($fieldvalue);
$value = $child->appendChild($value);
} // foreach
} // while
// get completed xml document
$xml_string = $doc->saveXML();
echo $xml_string;
但是,當我執行上面的我得到這個錯誤:
Fatal error: Uncaught exception 'DOMException' with message 'Namespace Error' in xml.php:21 Stack trace: #0 xml.php(21): DOMElement->setAttributeNS(' http://www.w3.o ...', 'xsi:schemaLocat...', 'uri:xxx...') #1 {main} thrown in xml.php on line 21
21行是第二個'setAttributeNS'行。
任何人都可以看到我要去哪裏錯了嗎?
