How to extract a portion of a string using regular expressions in Java

It looks like all that's happening is that you're appending

mycheck/report.html

..?

Yes. But in some cases I remove some portion of it like "sbtest/mylog_results.html" and in some other cases I don't need to remove.

So it is not actually just adding "mycheck/report.html" to the end of each link.

Hope this explains better

Thanks,

You'd have to define the rules, otherwise  it's impossible to say

You are right. Here is the rule:

This part is fixed:

http://www-internal.mywork.com/mywork/devel/sandbox/ANYTEXT/

The rest is not clear. But let me try to make a rule.

Apqr_test_mytests/glnxa64
mytests_logs/02-23-2011/glnxa64
prequal_testlog/Apqr_j123456_mytests/glnxa64/sbtest/mylog_results.html
prequal_testlog/Apqr_j123456_mytests/glnxa64/sbtest/mylog_results.html
MERGE_mytests/glnxa64_2011-02_sidCopy


From these example cases the rule is:
Note: Parathesis can be ignored. They are not part of the rule. I just used them to group parts.

http://www-internal.mywork.com/mywork/devel/sandbox/ANYTEXT/ ( 1 or many ANYTEXT/ ) ( 1 or 0 ANYTEXT.html )


Thanks,

Still, not quite clear to me what is the rule:

I see, you start from:

http://www-internal.mywork.com/mywork/devel/sandbox/ANYTEXT/ ( 1 or many ANYTEXT/ ) ( 1 or 0 ANYTEXT.html )



You are adding mycheck/report.html
 but you are removing some part, where, I guess, there is already report.

But how would one know, say,  that "/sbtest/" should also be removed?

You are right.

The rule that I wrote is for the match only. Now from this match I want to remove the part to the beginning of sbtest if there is any sbtest. And add mycheck/report.html

If there is no sbtest then directly add mycheck/report.html.

And from the rule I have given before, we don't know how many directories we have (ANYTEXT/) until the x.html file.

I hope it is clear now.

Thanks,

Don't know about regular expressions, but this is how you can do it with regual java:

String s1 = s.substring(0, s.lastIndexOf("/"));
if(s1.endsWith("sbtest"))s1 = s1.substring(0,s1.lastIndexOf("/"));
s1 += "/mycheck/report.html";

Hi Yan,
In your solution, I think we miss one more directory I guess. I think CEHJ's solution does not have this problem.


Case: http://www-internal.mywork.com/mywork/devel/sandbox/abcdef/Apqr_test_mytests/glnxa64

Result: http://www-internal.mywork.com/mywork/devel/sandbox/abcdef/Apqr_test_mytests/mycheck/report.html

Expected: http://www-internal.mywork.com/mywork/devel/sandbox/abcdef/Apqr_test_mytests/glnxa64/mycheck/report.html

Thanks,

'suffix' in my example is of course

"/mycheck/report.html"

Yes, you are right; CEHJ's is more general, I assumed that sbtest is always the last folder which contains the .html file

Thanks guys...

:)
