在元素的属性上保留前缀

Question

我有以下代码来获取RichText元素的属性。这些属性要么具有s7:之类的前缀，要么根本没有前缀。

<?php
$url = "http://testvipd7.scene7.com/is/agm/papermusepress/HOL_12_F_green?&fmt=fxgraw";    
$xml = simplexml_load_file($url);       
$xml->registerXPathNamespace('default', 'http://ns.adobe.com/fxg/2008');
$xml->registerXPathNamespace('s7', 'http://ns.adobe.com/S7FXG/2008');
$textNode = $xml->xpath("//default:RichText[@s7:elementID]");

function pr($var) { print '<pre>'; print_r($var); print '</pre>'; }

$result1 = array();
$result2 = array();
foreach($textNode as $node){
    $result1[] = $node->attributes('http://ns.adobe.com/S7FXG/2008');
    $result2[] = $node->attributes();

}

$text = array_merge($result1,$result2);

pr($text);

?>

输出

Array

                    [columnCount] => 1

                    [fontSize] => 19

                    [height] => 29
                )

        )

)

$result1[]中收集的所有属性都应具有s7:前缀。但是当它存储来自xml的数据时，它会从这些属性中剥离s7:。您可以看到这一点，因为键0和1的数组值已删除前缀。我需要前缀留在那里，所以它看起来像这样：

[s7:caps] => none
[s7:colorName] => 
[s7:colorValue] => #518269
[s7:colorspace] => rgb
[s7:elementID] => smalltext

etc...

如何防止剥离前缀，或者在构建阵列时如何将其添加回去？

不确定为什么PHP会从提取中省略命名空间 - 也许在libxml中更有知识的人可以提供帮助 - 但在提取后重命名它们很简单。

//some sample XML - get the attributes
$xml = "<root name='root'><node id='1'>hello</node></root>";
$doc = new SimpleXMLElement($xml);
$attrs = $doc->xpath('//@*');

//iterate over array and add in namespace prefixes      
foreach($attrs as $key => $val) {
    $attrs['s7:'.$key] = $val;
    unset($attrs[$key]);
}
