Checking syntax and capturing the groups correctly

Hello all,

  I need to check the syntax of the following

DataLog(0x22,Int,0x23 + 0x44,Int,0x24,Int,0x55,Octal,33 +
4,Hex)

I have the following RegEx for this which is

^s*DataLogs*(s*(?:(?:(d+|0x[da-fA-F]+|[_a-zaA-Z][d_a-
zaA-Z]*)
s*(?:([+-])s*(d+|0x[dA-Fa-f]+)){0,1}s*,s*(UByte|UShor
t|UInt|
Byte|Short|Int|Float|Hex|Binaryctal))(?:
s*,s*(d+|0x[da-fA-F]+|
[_a-zaA-Z][d_a-zaA-Z]*)s*(?:([+-])s*(d+|0x[dA-Fa-f]+))
{0,1}s*,
s*(UByte|UShort|UInt|Byte|Short|Int|Float|Hex|Binaryctal)s*)
*)
{0,1}s*)s*$

Which will work fine, so long as I am checking my syntax,
but it fails
at capturing the "+ 0x44" and "+ 4"
which will be captured under group
6 and group 7.  If I run the RegEx against this input I will
get the
following groups (omitting groups 1 to 4)

Group 5
  Capture '0x23'
  Capture '0x24'
  Capture '0x55'
  Capture '33'
Group 6
  Capture '+'
  Capture '+'
Group 7
  Capture '0x44'
  Capture '4'
Group 8
  Capture 'Int'
  Capture 'Int'
  Capture 'Octal'
  Capture 'Hex'

My problem is that the items in Group 6 and Group 7 do not
properly
align themselves to groups 5 and 8. Currently, I am at a
lost on how
to create a RegEx that will capture and align all the
elements
(correct term?) correctly. Right now, I am forced to run
this RegEx
just to check the syntax of the statement, then run the
following
RegEx just to capture the groupings correctly..

s*(?:s*(d+|0x[da-fA-F]+|[_a-zaA-Z][d_a-zaA-Z]*)s*(?:([
+-])s*(d
+|0x[dA-Fa-f]+)){0,1}s*,s*(UByte|UShort|UInt|Byte|Short|I
nt|Float|
Hex|Binaryctal)s*)


I would like to create one RegEx that will check the syntax
and group
everything correctly. Is there a way to do this that I am
missing?

Mark
