replaceAll(.....

[sgxbytes]

Hi,
[code=java]
String s = "hello in the (?hell?)";
s = s.replaceAll("? ", "\"");
[/code]
i hav a string s as shown above
i want to replace ? with "

the output should be like

hello in the ("hell")
i tried the using replaceAll replaceAll("(?" , "\"");
but i am getting an error like

java.util.regex .PatternSyntaxE xception: Dangling meta character '?' near index 0


can anyone suggest me how to go ahead with this.

Regards
Raj

the output should be of this format


hello in the (“hell”)


its not double quote for hell


i tried this way for replacing the first (? with (“


s = s.replaceAll("\ \(?" , "(“");


but i am getting o/p as


(“h(“e(“l(“l(“o (“ (“i(“n(“ (“t(“h(“e(“ (“(“?(“h(“e(“l( “l(“?(“)(“

I believe you need to escape the ? with a \. You would in Perl, at least, and I see no reason not to assume the same in Python.

Just use [CODE=java]yourString.repl aceAll("\\?", "\"");[/CODE]

Check this page from the Sun Regular Expression Lesson. It shows you, that '?' is indeed a quantifier and therefore has to be escaped as shown in the previous posts.
