推荐答案

有些字符不允许出现在 XML 文档中，即使您将数据封装在 CDATA 块中也是如此.

There are a few characters that are dissallowed in XML documents, even when you encapsulate data in CDATA-blocks.

如果您生成了文档，则需要对它进行将其删除.如果你有一个错误的文档，你应该在尝试解析它之前去掉这些字符.

If you generated the document you will need to strip it out. If you have an errorneous document, you should strip away these characters before trying to parse it.
