如何使用 SimpleXML 解析包含自定义命名空间的 XML?

2022-01-14 00:00:00 xml namespaces php

我想知道如何解析 XML 中名称中包含 : 的值.我一直在使用:

I'm wondering how to parse values in XML that appear to have : in their name. I've been using:

$response   = file_get_contents($url);
$data = simplexml_load_string($response);

然后做一个:

foreach($data->item as $key => $current){

但是，我收到的最新提要之一在提要名称中有冒号，如下例所示:

However, one of the latest feeds that I've been given has colons in the name of the feed as seen in the example below: 

<item>
  <title>foo</title>
  <description>foo</description>           
  <ccc:fid>10</ccc:fid>
  <ccc:bid>6</ccc:bid>
 </item>

当我尝试创建 $current->ccc:bid 时，php 并不高兴(理所当然).有没有办法解决这个问题?

When i try to create a $current->ccc:bid php does not get to happy (rightfully so). Is there any way to get around this?

推荐答案

ccc:fid的用法是命名空间的扩展，需要在xml中声明才能在simplexml等库中使用.

the usage of ccc:fid is an extension of the namespace which needs to be declared in xml in order to be able to use it in libraries like simplexml.

以下是命名空间中的一些描述示例:

Here are some examples of descriptions of usin a namespace:

  • http://www.w3.org/TR/1999/REC-xml-names-19990114/
  • http://www.w3.org/TR/xml-names/

希望对您有所帮助，尽管它有点复杂.

Hope that helps, albeit it is a little complicated.
