如何加载上述xml

提前谢谢

更新：如果我在每个字段后面放一个换行符，那么我可以读取数据。。。我怎样才能解决这个问题？其他工具不需要换行符，我无法更改源数据

格式化的xml：

<?xml version="1.0" encoding="UTF-8" ?>
<Feed xmlns="http://www.xx.com/PRR/ProductFeed/1.0"
              name="xx"

您的正则表达式字符串似乎需要一个新行字符：

\\n\\s*

将此更改为[\n\s]*应该可以使用

我可以格式化xml，现在可以读取类别，但无法读取产品，因为其中包含嵌入的变体。如何加载此xml？

\\n\\s*
