我正在使用一些 PHP 来使用 DOM 扩展从数据库创建 XML。
基本上,我需要创建一个 NameSpace 并向其添加 3 个属性:
<NameSpaceName xmlns="uri:xxx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="uri:xxx">
我写的完整代码如下:
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;
但是当我执行上面的命令时,我得到了这个错误:
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
第 21 行是第二个“setAttributeNS”行。
谁能看出我哪里出错了?
最佳答案
schemaLocation 未在命名空间 http://www.w3.org/2000/xmlns/
中声明,但在 http://www.w3.org/2001/XMLSchema-实例
<?php
// create a new XML document
$doc = new DomDocument('1.0', 'UTF-8');
// create root node
$root = $doc->createElementNS('http://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/2001/XMLSchema-instance', 'schemaLocation', 'http://xxx');
echo $doc->savexml();
打印
<?xml version="1.0" encoding="UTF-8"?>
<PayerRecords xmlns="http://xxx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xxx"/>
