Question

Im trying to do a regular expression to get something like this:

The string can be

/dira/dirb/dirc/dirn?e=0?e=0?e=3?e=0?e

or

/dira/dirb/dirc/dire/dirw/dirw/diw?e=?e=?e=3?e=?e

(The number of subdirs is variable)

I need to capture /dira/dirb/dirc/dirn?e=0 if the first e have value or /dira/dirb/dirc/dirn?e= if the first e dont have value:

I have this:

(.+)(\?e=\d?)

Im try with http://gskinner.com/RegExr/ but i dont find nothing.

Answer 1

Use this regex: (/dir?.)+(\?e=\d*)+\?e

Or, if the diw at the end of the second example isn’t just a mistake in your post, then your regex should be (/dir.)+(\?e=\d*)+\?e.
