如何仅从Freemarker中的字符串中提取字母？

Question

Anyone expert with Freemarker? One of my third-party company uses freemarker, and I don't really know a lot of it.

I just want to take alphabet from string:

Example:

JAVA2015123100001 -> JAVA
PHYTON2015123100002 -> PHYTON

In PHP, I can do it using preg_replace like this.

$output = preg_replace('#\d.*$#', '', $string);

How to do it in Java Freemarker?

Answer 1

理想情况下，您会做同样的事情：

<#assign string = string?replace("\d.*", "", "r")>
