regular expression to get string in between special charecters

Question

Iam trying to get the string october from the string ["october"] i tried with replace method

 tagNo = tagNo.replaceAll("\\[|\\]", ""); \\ it prints "october"

i cant replace quote with "" .

 tagNo = tagNo.replaceAll("\\[|\\]", "").replaceAll("\"", "\\\\\"");

not replacing quotes prints \\"october\\"

But i prefer to use a single code

using regex code how can i get the string with out quotes and square bracket

Answer 1

You need to slightly correct your regex. You haven't put any rule for removing double quote. Try using this,

tagNo = tagNo.replaceAll("(\\[|\"|\\])+", "");

Answer 2

 tagNo = tagNo.replaceAll("[^a-zA-Z]+","");

Answer 3

 tagNo = tagNo.replaceAll("\\[\"", "");
 tagNo = tagNo.replaceAll("\"\\]", "");
