How to write !,#,& in xml file?

推荐答案

您不能在元素名称中使用该字符.元素名称必须以字母或下划线开头.之后，还可以使用数字，句点，连字符和下划线.冒号也可以用于命名空间，不能使用其他字符.另外，不允许以"xml"开头的名称.

祝您好运！

You can''t use that character in element names. Element names need to start with a letter or underscore. After that, digits, period, hyphen and underscore are also allowed. Colon can also be used and for namespaces.Other characters can''t be used. Also, starting the name with "xml" isn''t allowed.

Good luck!

您的问题是错误的，因为您可以在xml文件中使用任何unicode字符，但不能以任何角色使用.
XML元素标记必须是xml规范中定义的名称: http ://www.w3.org/TR/REC-xml/#NT-名称 [ ^ ].如我所见，您的不祥字符都不符合.

Your question is wrong, because you can use any unicode character in an xml file, but not in any role.
XML element tag has to be a name as defined in the xml specification: http://www.w3.org/TR/REC-xml/#NT-Name[^]. As I see, neither of your ominous characters comply.
