String manipulation

Say i have a string representing a url such as:

String myUrl = "http://kpldb:8083/hartlepool/communityPortalHome/content/councilGateway/?view=Standard$a=5441"

What it the best and most cost effective way of taking the string and changing 'view=Standard' to 'view=TextOnly', bearing in mind the string will not always be the same length and $a=5441 will not always be on the ene

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Something like:

            String myUrl = "http://kpldb:8083/hartlepool/communityPortalHome/content/councilGateway/?view=Standard$a=5441";
            final String TARGET = "view=Standard";
            final String NEW = "view=TextOnly";
            int start = -1;

            if ((start = myUrl.indexOf(TARGET)) > -1) {
                  StringBuffer sb = new StringBuffer(myUrl);
                  sb.delete(start, start + TARGET.length());
                  sb.insert(start, NEW);
What JDK do you use? If 1.4 you can use replace.

Venabili is almost right ;-)  It's replaceAll(), not replace() ;-)

If you are using 1.4, you could do the following:

        String orig = "http://kpldb:8083/hartlepool/communityPortalHome/content/councilGateway/?view=Standard$a=5441";
        String replaced = orig.replaceAll("view=Standard", "view=TextOnly");

Possible problems with those approaches is if the String contains the text 'view=Standard' elsewhere in the url. If it is possible that this is the case then you'll need to parse the URL to perform the replacement. Let me know if this is the case and I'll show you a bullet proff approach.

No with my approach ;-)
No=Not ;-)

Don't worry. Repetition is not an issue anyway:

1. it can't be included before the query string
2. if it occurs more than once in the query string it'll be ignored by the server after the first occurrence anyway

Yes it can have problems.
replaceFirst() is another alternative (aside from the fact that the point is now moot anyway ;-))
>>now moot

now academic surely? ;-)
