simplexml 并访问 feedburner 的: [英] simplexml and accessing feedburner's :

问题描述

我正在尝试使用 simplexml 来读取 feedburner xml.我可以读取 xml 中的每个属性，但不能读取其中带有 ':' 的键.示例feedburner:origLink".当我对项目进行 vardump 时，那些带有 : 的键不会出现.我不能像 $s->item->feedburner:origLink.

I'm trying trying to use simplexml to read a feedburner xml. I can read every properties in the xml but not the keys with ':' in it. Example "feedburner:origLink". When I vardump the items, those keys with : doesn't show up. And I can't do like $s->item->feedburner:origLink.

推荐答案

您正在处理命名空间和 这篇 Sitepoint 文章 看起来是一个很好的长篇解释.或者对于更简洁的版本，请查看 PHP SimpleXML此处代码> 文档.

You're dealing with namespaces, and this Sitepoint article looks like a good long explanation. Or for a more concise version, look here in the PHP SimpleXML docs.

来自文档:

<?php
$xml = '<example xmlns:foo="my.foo.urn">
  <foo:a>Apple</foo:a>
  <foo:b>Banana</foo:b>
  <c>Cherry</c>
</example>';

$sxe = new SimpleXMLElement($xml);

$kids = $sxe->children('foo');
var_dump(count($kids));

$kids = $sxe->children('foo', TRUE);
var_dump(count($kids));

$kids = $sxe->children('my.foo.urn');
var_dump(count($kids));

$kids = $sxe->children('my.foo.urn', TRUE);
var_dump(count($kids));

$kids = $sxe->children();
var_dump(count($kids));
?>

输出:

int(0)
int(2)
int(2)
int(0)
int(1)
