推荐答案

您可以使用正则表达式解决此问题.
请参见 XQuery和XPath正则表达式 [

You can use a regular expression to solve this problem.
See XQuery and XPath Regular Expressions[^]

Specifically look into

fn:tokenize(subject, pattern, flags)

这种情况下的正则表达式可以是

The regex in this case could be

:(?<data>[a-z]+,[a-z]+)

注意:此正则表达式仅在您提出问题的特定情况下有效.

Note: This regex will only work under the specific circumstances you have given in your question.
