Notice that the codepoints-to-string example also uses two of the new XPath value comparison operators: lt (less than) and gt (greater than).

请注意，codepoints-to-string 的例子还用到了两个新的 XPath 值比较 运算符：lt（小于）和 gt（大于）。

The new string-to-codepoints and codepoints-to-string functions of XPath 2.0 give you a means to manipulate the characters that make up a string.

XPath 2.0新增函数string - to - codepoints和codepoints - to - string提供了操纵字符串字符的方法。
