XML: What is the difference among string, normalized string and token ?

Question

I am a beginner and developing various layouts but I am confused how to use both efficiently to achieve a good approach.

Answer 1

There are minor differences among these three types of data types. Please find the differences as mentioned.
1. String : String is a data type which contains characters, line feed, carriage returns and tabs. So if any XML element has data type String, it can contain all the mentioned things.
2. Normalized String: This data type is similar to String data type but XML parser removes line feed, carriage return and tabs.
3. Token: When this data type is used for a XML element, XML parser takes similar action as it does for normalizedstring also it removes extra leading and trailing spaces.
