解析一个动态大小的字符串 [英] Parse a dynamically sized string

问题描述

我有一个变量:

set myvar="26:deployment.javaws.jre.0.product=1.8.0_111"

我想在jre之后检索值.和.product，它们将是整数0.在此之间的值将始终是整数.该变量的字符串可能会稍有变化，但是[jre.] [integer] [.product]的格式将始终保持不变.因此，我不能只使用硬编码值来获取子字符串，因为如果说字符串开头的第一位数字是3位而不是2位长，那么字符串每次都可能不同，并且在开始处有更多字符.我该怎么办?

I want to retrieve the value after the jre. and .product which would be the integer 0. The value in between here will always be an integer. The variable can string can change slightly, but the format of [jre.][integer][.product] will always stay the same. Because of this I cant just get the substring using hardcoded values because the string may be different each time and have more characters at the beginning if say the first digit at the beginning of the string is 3 digits instead of 2 long. How can I do this?
