在java中用字符串替换正则表达式

Question

In java I am using regex \\".*?\\" . I used this for replacing all the string with doublequote with a term String.

Ex:
INPUT: Functions.unescapeJson("test")
Result : Functions.unescapeJson("String") 

But now I wanted to exclude some string if they contains double quote. So, I am using / as the escape character. How to achieve this.

Ex:
INPUT: Functions.getJsonPath(Functions.getJsonPath(Functions.getJsonPath(Functions.unescapeJson("test"), "m2m:cin.con"),"payloads_ul.dataFrameOutput"),"[/"Dimming Value/"]")

RESULT: Functions.getJsonPath(Functions.getJsonPath(Functions.getJsonPath(Functions.unescapeJson(String), String),String),String)

But the result I am getting if I use the previous regex is:

Functions.getJsonPath(Functions.getJsonPath(Functions.getJsonPath(Functions.unescapeJson(input.mIntegerm/:sgn.nev.rep), String),String),StringDimming ValueString)

How to achieve this using regex if it finds / it should neglect without replacing original string.

The code that I am using

public static void main(String[] args) {
    String STRINGVALIDATIONREGEX = "\".*?\"";
    String formula = "Functions.getJsonPath(Functions.getJsonPath(Functions.getJsonPath(Functions.unescapeJson(input.m2m/:sgn.nev.rep), \"m2m:cin.con\"),\"payloads_ul.dataFrameOutput\"),\"[\"Dimming Value\"]\")";
    System.out.println(formula.replace(STRINGVALIDATIONREGEX, "String"));
}

Answer 1

您可以使用此正则表达式：

\"(\/?.)*?\"

Answer 2

Use [^/] to match anything that is not a slash.

For example, [^/]?\\".*[^/]?\\" would catch quotes not preceded by /

Answer 3

"((?:[^"]|(?<=\/)")*)"

1. " match a "
2. [^"] match a non-quote character
3. | or
4. (?<=\\/)") a quote character that is preceded by a /
5. * match sub-expressions 2 - 4 zero or more times.
6. " match a "

See Regex demo

If you believe that a string such as "abc/" is invalid, then you should use the stricter regex:

"((?:[^"\/]|\/")*)"

1. " match "
2. [^"\\/] match a any character that isn't a quote for /
3. | or
4. \\/" match a /" combination
5. * match sub-expressions 2 - 4 zero or more times.
6. " match a "
