Hi to all,
I'm trying to compare two files, containing share price quotes, using =
only the first part of each line (ie, the exchange Code). I'm not =
interested in the differences in quotes, but am trying to determine =
which Codes appear in one file but not in the second file. I realise =
that I need to use Regular Expression(s) but I'm not having any luck and =
would appreciate some help.
The original data lists look like this:
BAR,20031126,0.062,0.065 =
BANIYD,20031126,212.73,212.73BAROA,20031126,0.00,0.00 =
BAR,20031126,0.062,0.065BGDOA,20031126,0.033,0.033 =
BGD,20031126,0.185,0.185BGF,20031126,0.115,0.115 =
BGDOA,20031126,0.033,0.033BGN,20031126,0.275,0.28 =
BGF,20031126,0.115,0.115BHL,20031126,0.00,0.00 =
BGN,20031126,0.275,0.28BHP,20031126,11.10,11.11 =
BHFHA,20031126,112.704,112.704BHPDMF,20031126,0.00,0.00 =
BHL,20031126,4.85,4.85 =
BHP,20031126,11.1,11.11 =
BHPDMF,20031126,5.25,5.25I would like the result, after applying a =
Regular Expression to the compare, to look like this:
BANIYD,20031126,212.73,212.73
BAR,20031126,0.062,0.065 BAR,20031126,0.062,0.065
BAROA,20031126,0.00,0.00 BAROA,20031126,0.02,0.02
BGDOA,20031126,0.033,0.033 BGDOA,20031126,0.033,0.033
BGF,20031126,0.115,0.115 BGF,20031126,0.115,0.115
BGN,20031126,0.275,0.28 BGN,20031126,0.275,0.28
BHFHA,20031126,112.704,112.704
BHL,20031126,0.00,0.00 BHL,20031126,4.85,4.85
BHP,20031126,11.10,11.11 BHP,20031126,11.1,11.11
BHPDMF,20031126,0.00,0.00 BHPDMF,20031126,5.25,5.25
TIA
Cheers,
John
