RegEx matching - stop first matching

this string must be checked, with regex ...

<u>str<b>#u #bold<em>#u b #ital<strike>#u b em #ic stri</strike>ng</em>also(bold)</b></u><u>str<b>#u #boldalso(bold)</b></u>

This is the regex

[^.?]>#(.*?) #

The matching must be contained follow values

<b>#u #
<em>#u b #
<strike>#u b em #
<b>#u #

but only was matched

b>#u #
m>#u b #
e>#u b em #
b>#u #

what is wrong? i think this expression-part must be updated 

[^.?]

thanks for your replay,

i modifed the expression 

(<(\w+)>#([^#]*)#)

for this (e.g.) string

   <strike> #u #String:Underline-Strike-1<b>#u strike #String:Underline-Strike-Bold </b></strike><strike>#u #String:Underline-Strike-2</strike>

it was all matched, but not for 

 <strike> #u #String:Underline-Strike-1

the WHITESPACE after ">" is the problem...

how to fix the regex?

EDIT

ok i find the solution by my self 

\s*

final

(<(\w+)>\s*#([^#]*)#)

use the following regex :

<\w+>#[^#]*#


Edit : Explanation of the expression :

  • < : it starts matching from <
  • \w+ : followed by one or more letters
  • >: and then closing >
  • # : followed by #
  • [^#]* : this will match just before of #
  • # : and then #

so

<\w+>#          [^#]*            #        Final Match
---------------------------------------------------------
'<b>#'          'u '            '#'     '<b>#u #'
'<em>#'         'u b '          '#'     '<em>#u b #'
'<strike>#'     'u b em '       '#'     '<strike>#u b em #'
'<b>#'          'u '            '#'     '<b>#u #'
