为什么此请求中的谷歌浏览器中没有显示数据？

Answer 1

不同的浏览器在处理无效XML方面有不同的解析引擎和差异。在这种情况下，Chrome（正确）比IE更严格。

要解决此错误，您需要更换＆amp;在&的以下行中，它是“＆amp;”的有效表示XML中的字符。

<CompanyName>Arnars Bud- & Landbrugsservice</CompanyName>

应该成为：

<CompanyName>Arnars Bud- &amp; Landbrugsservice</CompanyName>

这很不幸，但你不能总是相信其他系统的XML输出会正确形成，所以要么检测它或清理它的一些逻辑总是谨慎的。

xmlParseCharRef：无效的xmlChar值为0
