My code:

我的代码:

$xml_data = new SimpleXMLElement('<?xml version="1.0"?><data></data>');
array_to_xml($invoice, $xml_data);
$xml = $xml_data->asXML();

$domxml = new DOMDocument('1.0');
$domxml->preserveWhiteSpace = false;
$domxml->formatOutput = true;
$domxml->loadXML($xml);
$xml_string = $domxml->saveXML();

I think the xml is in the right format so why is this failing?

我认为xml的格式是正确的，为什么会失败呢?

Edit:

编辑:

Here is the dynamic array before converted into xml using XMLSimpleElement, is there anyway to remove <0> before converted into xml?:

这是使用XMLSimpleElement转换为xml之前的动态数组，在转换为xml之前是否有删除<0>的方法?

2 个解决方案

#1

As mentioned in the comments the issue is with your number elements, <0>. That is an invalid element name. You could manually modify the XML file if this is a static file, remove or rename, use a regex, or suppress the error. If you suppress you will have to remember that in the future, it will never tell you about errors.

正如评论中提到的，问题在于您的number元素<0>。这是一个无效的元素名。如果这是一个静态文件，您可以手动修改XML文件、删除或重命名、使用regex或抑制错误。如果你压抑自己，你必须记住，在未来，它永远不会告诉你错误。

Regex approach:

正则表达式的方法:

$invoice = preg_replace('~<(/?\d)~', '<number$1', $invoice);

Regex demo: https://regex101.com/r/pZ3sJ4/1

Regex演示:https://regex101.com/r/pZ3sJ4/1

One suppression option:

一个抑制选项:

libxml_use_internal_errors(true);
$domxml->loadXML($invoice);
libxml_clear_errors();

With this approach you can still retrieve the errors pretty easily.

使用这种方法，您仍然可以很容易地检索错误。

e.g.

如。

libxml_use_internal_errors(true);
$domxml->loadXML($invoice);
$xml_string = $domxml->saveXML();
$errors = libxml_get_errors();
foreach ($errors as $error) {
    echo $error->message;
}
libxml_clear_errors();

Second suppression option:

第二个抑制选项:

@$domxml->loadXML($invoice);

yuck..

恶心. .

Third simple non-programming option, just edit the file manually:

第三个简单的非编程选项，只需手动编辑文件:

<item1>
            <taxes><name0>E</name0></taxes>
            <title>0022-56</title>
            <quantity>12</quantity>
            <description>Zoom (TM) DayTripper Sling Compu-Messenger; TBD TBD</description>
            <unit_price>67.02</unit_price>
        </item1>

Element names must start with a letter or underscore

元素名称必须以字母或下划线开头。
