[英]Why, I am getting a Fatal Error with commented $start var?
When I use $start var like this: 当我使用$ start var时:
$start = "<?xml version='1.0' encoding='utf-8'?/>";
I get a fatal error: 我收到一个致命的错误:
Fatal error: Uncaught Exception: String could not be parsed as XML in /home/users/....../test.php:6 Stack trace: #0 /home/users/....../test.php(6): SimpleXMLElement->__construct('<?xml version='...') #1 {main} thrown in /home/users/....../test.php on line 6
致命错误:未捕获异常:在/home/users/....../test.php:6中无法将字符串解析为XML堆栈跟踪:#0 /home/users/....../test。 php(6):SimpleXMLElement - > __ construct('<?xml version ='...')#1 {main}在第6行的/home/users/....../test.php中抛出
How can I generate nice formatted XML tag for XML? 如何为XML生成格式良好的XML标记?
$start = "<xml version='1.0' encoding='utf-8' />";
//$start = "<?xml version='1.0' encoding='utf-8'?/>";
$gmXML = new SimpleXMLElement($start);
$offers = $gmXML->addChild('offers');
Header('Content-type: text/xml;');
echo $gmXML->asXML();
What I need is: 我需要的是:
<?xml version='1.0' encoding='utf-8'?>
The problem is that <?xml version='1.0' encoding='utf-8'?/>
(although with a slight mistake in it anyway) doesn't actually define an XML element as it has no root node. 问题是
<?xml version='1.0' encoding='utf-8'?/>
(尽管它有一点点错误)实际上并没有定义XML元素,因为它没有根节点。
With your current code, you would have to add the <offers>
element to the XML to give it the actual element content... 使用当前代码,您必须将
<offers>
元素添加到XML中,以便为其提供实际的元素内容...
$start = "<?xml version='1.0' encoding='utf-8'?><offers />";
$gmXML = new SimpleXMLElement($start);
Header('Content-type: text/xml;');
echo $gmXML->asXML();
Also note the end of the definition is ?>
and not ?/>
还要注意定义的结尾是
?>
而不是?/>
As your other version of the XML... 作为您的其他版本的XML ...
$start = "<xml version='1.0' encoding='utf-8' />";
This actually declares a root node called <xml>
. 这实际上声明了一个名为
<xml>
根节点。
