XML;


 $simpleXml = new SimpleXMLElement($xmlstr);

 var_dump((array) $simpleXml);

命名空间错误:第 35 行的/home/sweb/www/tmp/sxml.php 中未定义视图中的命名空间前缀角色

在/home/sweb/www/tmp/sxml.php 第 35 行

推荐答案

XML 解析器依赖于文档必须严格有效的事实，而您的文档格式不正确.它需要 actor 的命名空间 URI.根元素应该是这样的:

XML parsers rely on the fact documents have to be strictly valid, and yours is not well-formed. It needs a namespace URI for actor. The root element should be along the lines of this:

<movies xmlns:actor="http://yoururl.com/">

只要您没有它，任何兼容的 XML 解析器都不会接受您的文档.

As long as you don't have it, no compliant XML parser will accept your document.
