Java 正则表达式问题？
我在 java 中遇到 RegEx 问题；
我的台词是：
CREATE CHAN:NAME=BTSM:1/BTS:2/TRX:5/CHAN:7,CHTYPE=TCHF_HLF,FHSYID=FHSY_0
我想要这个：
content [0] = BTSM:1/BTS:2/TRX:5/CHAN:7
content [1] = CHTYPE
content [2] = TCHF_HLF
content [3] = FHSYID
content [4] = FHSY_0
我写了这个：
String[] content = value.split("^=/:|,|=|,$");
但这不起作用:( 请告诉我这件事...... 多谢 ...
I have a problem with RegEx in java;
my line is :
CREATE CHAN:NAME=BTSM:1/BTS:2/TRX:5/CHAN:7,CHTYPE=TCHF_HLF,FHSYID=FHSY_0
and I want this :
content [0] = BTSM:1/BTS:2/TRX:5/CHAN:7
content [1] = CHTYPE
content [2] = TCHF_HLF
content [3] = FHSYID
content [4] = FHSY_0
I wrote this :
String[] content = value.split("^=/:|,|=|,$");
but it's not work :(
so kindly inform me about that...
Thanks a lot ...

应该做你想做的事。
我不明白你是如何推导
"^=/:|,|=|,$"所以我无法告诉你哪里出了问题，但这里是它的作用的细分。如果字符串
=/:出现在开头，则会跳过它，并在结果的开头粘贴一个空字符串。也许您想要一个字符集。[=/:]是匹配这些字符之一的任何出现的字符集。这将在任何逗号上分开。
这将在任何等号上分开。
这将跳过输入末尾的逗号（或输入末尾的换行符之前），如果跳过，将在分割结果的末尾粘贴一个空字符串。
should do what you want.
I don't understand how you derived
"^=/:|,|=|,$"so I can't tell you where you went wrong, but here's a breakdown of what it does.This is going to skip the string
=/:if it occurs at the beginning and stick an empty string at the start of the results. Perhaps you wanted a character set.[=/:]is a character set that matches any occurence of one of those characters.This will split on any comma.
This will split on any equals sign.
This will skip a comma at the end of the input (or just before a newline at the end of input) and if skipped will stick an empty string on the end of the split result.
我不知道你传递给 split() 的东西到底是什么，但你需要做的是在任何出现
、或 < 的情况下进行拆分删除第一个=之前的所有内容后。这可以通过以下方式完成：String[] content = (value.substring(value.indexOf('=') + 1)).split("[,=]");I don't know what the Hell that thing you're passing to
split()is, but what you need to do is to split on any occurence of,or=after removing everything up through the first=. This can be accomplished with:String[] content = (value.substring(value.indexOf('=') + 1)).split("[,=]");
