我有一个XML文件，我从卷曲响应中得到。 当我在浏览器中调用该文件时，它看起来像这样：
<result xsi:schemaLocation="http://mylink.com/xsd/1.0/item.xsd">
<item id="12345">
<name>Product X</name>
<images>
<image lastUpdate="2017-01-18T11:33:05+02:00">
<sizes>
<size maxwidth="74" width="74" height="59" filesize="2452" xlink:href="http://mylink.com/images/1008374"/>
<size maxwidth="320" width="320" height="256" filesize="34502" xlink:href="http://mylink.com/images/1008375"/>
<size maxwidth="800" width="750" height="600" filesize="175894" xlink:href="http://mylink.com/images/1008376"/>
</sizes>
</image>
</images>
</item>
</result>
但是当我用SimpleXmlElement解析它时，它看起来像这样：
SimpleXMLElement Object
(
[item] => SimpleXMLElement Object
(
[@attributes] => Array
(
[id] => 12345
)
[name] => Product X
)
[images] => SimpleXMLElement Object
(
[image] => Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[lastUpdate] => 2017-01-18T11:33:05+02:00
)
[sizes] => SimpleXMLElement Object
(
[size] => Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[maxwidth] => 74
[width] => 74
[height] => 74
[filesize] => 3476
)
)
[1] => SimpleXMLElement Object.....
因此我的图像节点中不再有xlink：href属性。我读了一些关于添加属性的内容，但我不知道在哪里，因为在生成SimpleXML-Element时会切断xlink元素。 有谁知道如何获得xlink属性？
