XML模式的PHP驗證十進制數錯誤

Question

我有這樣的模式：

<?xml version="1.0" encoding="UTF-8"?> 
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> 
    <xs:simpleType name="errorType"> 
     <xs:restriction base="xs:decimal"> 
      <xs:totalDigits value="28"/> 
      <xs:fractionDigits value="16"/> 
      <xs:minExclusive value="0"/> 
      <xs:maxExclusive value="1000000000000"/> 
     </xs:restriction> 
    </xs:simpleType> 
    <xs:element name="TEST"> 
     <xs:complexType> 
      <xs:sequence> 
       <xs:element name="newElement" type="errorType" minOccurs="1" maxOccurs="unbounded"/> 
      </xs:sequence> 
     </xs:complexType> 
    </xs:element> 
</xs:schema> 

而且有這樣的XML：如果我驗證使用PHP的DOMDocument schemaValidate功能它，我得到的十進制數錯誤

<?xml version="1.0" encoding="UTF-8"?> 
<TEST xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 

    <newElement>123456789012.5000000000000003</newElement> 
    <newElement>12345678901.5000000000000003</newElement> 
    <newElement>1234567890.5000000000000003</newElement> 
    <newElement>123456789.5000000000000003</newElement> 
    <newElement>123456789.123456789</newElement> 
    <newElement>123456789.500000000000003</newElement> 
    <newElement>1234567890.500000000000003</newElement> 
    <newElement>12345678901.500000000000003</newElement> 
    <newElement>123456789012.50000000000003</newElement> 

</TEST> 

總數大於27位。有什麼辦法可以解決這個問題嗎？

完整代碼：

<?php 


function libxml_display_error($error) 
{ 
    $return = "<br/>\n"; 
    switch ($error->level) { 
     case LIBXML_ERR_WARNING: 
      $return .= "<b>WARNING:</b> $error->message "; 
      break; 
     case LIBXML_ERR_ERROR: 
      $return .= "<b>ERROR:</b> $error->message "; 
      break; 
     case LIBXML_ERR_FATAL: 
      $return .= "<b>FATAL:</b> $error->message "; 
      break; 
    } 
    $return .= " on line <b>$error->line</b>\n"; 
    return $return; 
} 

function libxml_display_errors() { 
    $errors = libxml_get_errors(); 
    foreach ($errors as $error) { 
     print libxml_display_error($error); 
    } 
    libxml_clear_errors(); 
}

Answer 1

一）改變這個標籤，你喜歡的任何值

<xs:totalDigits value="28"/> 

B）輪數比的限制較小（可能是你的號碼是29個位數，包括小數點）

只是模仿模式要求的限制

<xs:restriction base="xs:decimal"> 
      <xs:totalDigits value="28"/> 
      <xs:fractionDigits value="16"/> 
      <xs:minExclusive value="0"/> 
      <xs:maxExclusive value="1000000000000"/> 
</xs:restriction>
