这是源xml：xml

这是 Adob​​e 制作的 fxg 文件的 xml。FXG 文档是有效的 xml，它基本上包含了可以编辑的文档的所有信息。此特定问题与可以在 FXG 中更改的文本有关，以便内容可以更改。

我正在尝试获取该元素中具有s7:elementID使用 xpath 相对位置的属性的所有 RichText 元素和属性。

源 XML 总共只有三个RichText元素，其中只有两个具有s7:elementID

<?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");

print("<pre>".print_r($textNode,true)."</pre>");

?>

在另一个问题的帮助下，我走了这么远。但是返回的数组不是我所期望的。像我一样设置 xpath，我希望它选择所有具有 的RichText元素，s7:elementID以及该元素的其他属性。但是，它没有获取这些元素的任何其他属性。这是它的输出：

Array
(
    [0] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [elementID] => smalltext
                )

        )

    [1] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [elementID] => largetext
                )

        )

)

如果我采用完全相同的 php 但像这样更改 xpath：

$textNode = $xml->xpath("//default:RichText");

我得到这个数组结果：

    [0] => SimpleXMLElement Object
        (

                        )

                )

        )

如果您注意到，前两个数组项甚至没有 的信息s7:elementID，但它们是应该的两个。第三个没有s7:elementID设计。

谁能解释为什么我得到这些意想不到的数组结果，显示了一些属性，而另一些则没有？

更新

Per dusan，我将 php 更新为：

$textNode = $xml->xpath("//default:RichText[@s7:elementID]");

现在数组只返回没有前缀的元素的属性。我需要所有属性，前缀而不是。

将 php 更改为此似乎可以获得所有属性，包括默认属性和s7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]"); // //default:RichText[@s7:elementID]/@*

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


foreach($textNode as $node){
    pr($node->attributes('http://ns.adobe.com/S7FXG/2008'));
    pr($node->attributes());
}
?>

现在它能够检索RichText元素的所有属性。如何将某些属性存储为特定变量？例如，如何为s7:elementID和fontSize属性设置变量？

随着//default:RichText/@s7:elementID您选择elementID属性，而不是RichText标签。

用这个：

$textNode = $xml->xpath("//default:RichText[@s7:elementID]");

更新： SimpleXMLElement ::attributes 文档说：

SimpleXML 制定了一个规则，为大多数方法添加迭代属性。不能使用 var_dump() 或其他任何可以检查对象的东西来查看它们。

因此print_r，没有向您显示所有信息。尝试使用它们的命名空间获取属性：

foreach($textNode as $node){
    var_dump($node->attributes('http://ns.adobe.com/S7FXG/2008'));
}
