[英]Java: Replace String (with brackets!)
I'm currently working on a small program that: 我目前正在开发一个小型程序,该程序:
Example for the conversion: abc (with a tab in between each of the parts), eg "its[ ]bracket" -> "itsabracket" with 转换示例:abc(每个部分之间都有一个制表符),例如“ its [] bracket”->“ itsabracket”
tagname [ ] a
in the config file ("[ ]" gets replaced with "a"). 在配置文件中(“ []”被替换为“ a”)。 a is the tag that tells me, what columns get converted, b is the original substring and c is the String b has to be converted into. a是告诉我要转换哪些列的标签,b是原始子字符串,c是必须转换为String的字符串。
The problem is: I already know that brackets (round, curly and square) are going to be used in the config file but I don't know, if it's going to be just a single one or maybe even longer phrases (with letters, digits,..) in between the brackets. 问题是:我已经知道配置文件中将使用方括号(圆形,卷曲和方括号),但是我不知道它是否只是一个或什至更长的短语(带字母,括号之间的数字。
String s = s.replaceAll(convert[i].original, convert[i].new);
for "[ ]" -> "a" writes [a] into the output file and if I do the following first, when it's reading the config file and saves everything in the "convert" array, it throws a PatternSyntaxException ("Unclosed character class near index 0"): for“ []”->“ a”将[a]写入输出文件,如果我先执行以下操作,则当它读取配置文件并将所有内容保存在“ convert”数组中时,它将引发PatternSyntaxException(“ Unclosed character靠近索引0“的类别):
if(ss.contains("[")) {
ss = ss.replaceAll("[", "\\[");
} else if(ss.contains("]")) {
ss = s.replaceAll("]", "\\]");
}
With 同
if(ss.contains("\\[")) {
ss = ss.replaceAll("\\[", "\\\\[");
} else if(ss.contains("\\]")) {
ss = s.replaceAll("\\]", "\\\\]");
}
it outputs "[a]" again. 它再次输出“ [a]”。
Any ideas, how I can make this work? 有什么想法,我该如何做呢?
Use String.replace It accepts character sequence unlike replaceAll.You dont have to use escape characters for [] etc. Use String.replace它接受与replaceAll不同的字符序列。您不必对[]等使用转义字符。
String s = s.replace(convert[i].original, convert[i].new);
input 输入
its[][]]bracket 其[] []]托架
tagname [ ] a 标记名[] a
output 产量
itsaa]bracket itsaa]托架
Hope this is what you want to achieve using your code. 希望这是您希望使用代码实现的目标。
