转换xml数组在php中的数组问题

Question

$data = 
    '<parent> 
     <child> 
     <EC>1</EC> 
     <Descript>Savings Accepted</Descript> 
     <Logic>RF > LF = PAID</Logic> 
     <Rules>RF is greater than PAID and LF is equal to PAID</Rules> 
     </child> 
     <child> 
     <EC>2</EC> 
     <Descript>Savings Declined</Descript> 
     <Logic>RF >= LF < PAID</Logic> 
     <Rules>RF greater/equal PAID, LF equal PAID</Rules> 
     </child> 
    </parent>'; 

file_put_contents('rules.xml', $data); 

$xml = simplexml_load_file("rules.xml") or die("Error: Cannot create object"); 

我无法转换。

您应该使用实体& lt;而不是<和& gt;代替>

$data = <<<'XML' 
<parent><child> 
    <EC>1</EC> 
    <Descript>Savings Accepted</Descript> 
    <Logic>RF &gt; LF = PAID</Logic> 
    <Rules>RF is greater than PAID and LF is equal to PAID</Rules> 
</child> 
<child> 
    <EC>2</EC> 
    <Descript>Savings Declined</Descript> 
    <Logic>RF &gt;= LF &lt; PAID</Logic> 
    <Rules>RF greater/equal PAID, LF equal PAID</Rules> 
</child></parent> 
XML; 
file_put_contents('rules.xml', $data); 
$xml = simplexml_load_file("rules.xml") or die("Error: Cannot create object"); 

print_r($xml); 

输出继电器

 
SimpleXMLElement Object 
(
    [child] => Array 
     (
      [0] => SimpleXMLElement Object 
       (
        [EC] => 1 
        [Descript] => Savings Accepted 
        [Logic] => RF > LF = PAID 
        [Rules] => RF is greater than PAID and LF is equal to PAID 
       ) 

      [1] => SimpleXMLElement Object 
       (
        [EC] => 2 
        [Descript] => Savings Declined 
        [Logic] => RF >= LF RF greater/equal PAID, LF equal PAID 
       ) 

     ) 

)
