的DOMDocument :: loadXML的（）：開始標記：在實體

Question

無效元素名稱這是我的xml：

<?xml version="1.0"?> 
<data> 
    <client_name>Awesome Client</client_name> 
    <account_number/> 
    <date_created>02/12/2016</date_created> 
    <form_number>4126</form_number> 
    <customer_po/> 
    <terms_name>Credit Card</terms_name> 
    <date_shipped>12/31/1969</date_shipped> 
    <billing_contact_email/> 
    <billing_contact_address_line_1/> 
    <billing_contact_address_line_2/> 
    <billing_contact_address_line_3/> 
    <billing_contact_address_line_4/> 
    <billing_contact_address_city/> 
    <billing_contact_address_state>British Columbia</billing_contact_address_state>

    <shipping_contact_address_line_2/> 
    <shipping_contact_address_line_3/> 
    <shipping_contact_address_line_4/> 
    <shipping_contact_address_city/> 
    <shipping_contact_address_state>British Columbia</shipping_contact_address_state> 
    <shipping_contact_address_postal/> 
    <shipping_contact_address_country>Canada</shipping_contact_address_country> 
    <billing_contact_first_name>another</billing_contact_first_name> 
    <billing_contact_last_name>client</billing_contact_last_name> 
    <client_rep_full_name>Rob Montebelli</client_rep_full_name> 
    <order_rep_full_name>Mark Graham</order_rep_full_name> 
    <job_name>77777</job_name> 
    <job_number>2620</job_number> 
    <event_type>Donor Gift</event_type> 
    <due_date>02/12/2016</due_date> 
    <shipping_method/> 
    <currency>CAD</currency> 
    <total_taxes>0.00</total_taxes> 
    <total_subtotal>1,760.16</total_subtotal> 
    <total>1,760.16</total> 
    <items> 
     <item0> 
      <taxes> 
       <0>E</0> 
      </taxes> 
      <title>1889-24</title> 
      <quantity>6</quantity> 
      <description>Carhartt (R) Signature Utility Duffel; TBD TBD</description> 
      <unit_price>159.32</unit_price> 
     </item0> 
     <item1> 
      <taxes> 
       <0>E</0> 
      </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> 
    </items> 
</data> 

我的代碼：

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

我認爲XML是正確的格式，爲什麼這是失敗的嗎？

編輯：

下面是使用XMLSimpleElement動態陣列之前被轉換成XML，反正是有除去< 0>之前被轉換成XML ?:

Answer 1

正如意見中提到的問題是與你的許多元素，<0>。這是一個無效的元素名稱。如果這是一個靜態文件，則可以手動修改XML文件，刪除或重命名，使用正則表達式或抑制錯誤。如果你壓抑，你將不得不記住，在將來，它永遠不會告訴你有關錯誤。

正則表達式的方法：

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

正則表達式演示：https://regex101.com/r/pZ3sJ4/1

一個抑制選項：

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

通過這種方法，你仍然可以很容易地檢索錯誤。

例如

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(); 

第二抑制選項：

@$domxml->loadXML($invoice); 

呸..手動

三簡單的非編程選項，只需編輯文件：

<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> 

Answer 2

Element names must start with a letter or underscore

觀看http://www.w3schools.com/xml/xml_elements.asp更多信息

變更

<taxes> 
    <0> E </0> 
</taxes> 

到

<taxes> 
    <t0> E </t0> 
</taxes> 

例如
