I need to help about writing regex for below string. I have tried lots of pattern but all failed.
I have a string like
package1[module11,module12,module13],package2[module21,module22,module23,module24,module25],package3[module31]
and I want to split this string like
package1
module11,module12,module13
package2
module21,module22,module23,module24,module25
package3
module31
I know it is weird to ask a regex from here but …
You can match using the pattern:
Example: http://www.rubular.com/r/rPUEWBoU1d
The pattern is pretty simple, really:
(\w+)– capture the first word (package1)\[(\w+(?:,\w+)*)– A sequence of at least one word (module11), followed by comma separated words (assuming they are well formed)\]In all cases, you may want to change
\wto your alphabet (maybe even[^,\[\]]– not comma or brackets). You also may want to check the whole string matches, as the above pattern may skip over unwanted parts (for example:a[b]$$$$c[d])
