我只需要所有<OrderDetails>的孩子

在测试中，我尝试简单地回显所有数据，然后设置变量。

function processxmldetails() 
$filexml='vl_rts.xml';
if (file_exists($filexml)) 
$xml = simplexml_load_file($filexml);
foreach ($xml->Orders->OrderDetails->children() as $Orders) 
echo $Orders . '<br>';

//end foreach

这仅与此相呼应：

3374
Y
Y
0

0.0000



Y
0


2119
test-product
39200
Test Product 1

1.0000
1
0
1
0
1
Y
1.0000
0.0000

我需要每个<OrderDetails> 真的在它自己的变量中，所以我可以检查它是哪个<OrderDetailID> 并相应地插入另一个数据库。

我怎样才能一个接一个地调用这些<OrderDetail>标签，然后检查它们的<OrderDetailID>是什么来执行任务，然后转到下一个<OrderDetail>？

【问题讨论】：

【参考方案1】：

你可以用这个：

<?php
function processxmldetails() 
    $filexml = 'vl_rts.xml';
    $data = array();

    if( file_exists( $filexml ) ) 
        $xml = simplexml_load_file( $filexml );
        $i = 0;

        foreach( $xml->Orders as $key => $orders ) 
            $j = 0;
            $data[ $i ] = array();

            $data[ $i ][ 'OrderID' ] = ( int ) $orders->OrderID;
            $data[ $i ][ 'OrderDetails' ] = array();

            foreach( $orders->OrderDetails as $key1 => $value ) 
                foreach( $value as $k => $v ) 
                    $data[ $i ][ 'OrderDetails' ][$j][ $k ] = ( string ) $v;
                
                $j++;
            
            $i++;
        
    

    return $data;

$result = processxmldetails();

foreach( $result as $key => $value ) 
    foreach( $value[ 'OrderDetails' ] as $k => $v ) 
        foreach( $v as $k1 => $v1 ) 
            echo $k1 .' = ' . $v1 . '<br />';
        
        echo '----<br /><br />----';
    

?>

OrderDetailID 标记内的所有数据现在都在数组中。您可以根据自己的要求使用它。希望这会有所帮助。

【讨论】：

好的，太棒了，谢谢。你能告诉我如何读取数组吗？就像我如何调用第一个 OrderDetails 第 1 行，然后是第 2 行等...然后是第二个 OrderDetails 第 1 行，第 2 行等...？非常感谢。我想我几乎明白了。所以像 $data[0][OrderID] 是第一个 OrderID 号，$data[2][OrderID] 是第二个 ID 号。我很难弄清楚如何调用其余部分。我知道，新手问题......对不起。你是最棒的，非常感谢！我需要 $data[0][OrderDetails][0][OrderDetailID] 并增加它们以插入它们。那一点，调用你上面写的代码，让我头疼不已。我能看到光！哇！【参考方案2】：

好吧，因为我不能假设这是我想出的这是我们作为示例的 XML 文件

<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

这是我们将用来提取信息的代码:)

$xml = simplexml_load_file("test.xml");

echo $xml->getName() . "<br />";

foreach($xml->children() as $child)
  
  echo $child->getName() . ": " . $child . "<br />";

这将是我们的输出

note
to: Tove
from: Jani
heading: Reminder
body: Don't forget me this weekend!

--旧代码--我知道这是错误的语言我的错误-- 使用 get child，您可以从每个元素中提取您需要的信息

xml.getChild(index)
xml.getChild(path)

http://processing.org/reference/XMLElement_getChild_.html

祝你好运:)

【讨论】：

非常感谢您的回答。我可以麻烦您举个简单的例子吗？我以前从未使用过。所以比如说我只想要第一个 OrderDetails，我想检查第一个 OrderDetailID 标签的编号，然后做一些花哨的事情，然后转到第二个 OrderDetails 并做同样的事情。非常感谢。我将添加另一个答案，以便我可以为您破解代码问题是，如果我要求太多，请告诉我，但我真的需要一个基于上述 XML 示例的示例。注意一个有两个而另一个只有一个我需要一种干净的方式来调用它们和它们的以便我可以继续使用脚本。非常感谢您的帮助。我会推荐提供的其他答案，他们会在我之前使用您的代码:)
