Iwork 09 Numbers Wildcard Parse for Column Cell Dat

Question

As a "Novice"
I ran into a problem I cannot find the answer in PDF..maybe lack of examples..
I have a table for "CT" data that has many rows imported via "CSV" sets
I have a column that is called "Radiation Dose"..say AA:16
In this cell, I want to extract and sum the "CTDIvol" data to another column cell (un-named)..say AD:16
Data looks like this
Example 1:
Topogram: kV=120 mAs=130  CHEST: kV=120 mAs=1058 CTDIvol=6.84 DLP=84.82  CHEST: kV=120 mAs=1055 CTDIvol=6.84 DLP=84.82
I only want the CTDIvol data and it summed for a total.
I would like to do again as a seperate function for say AE:16 for "DLP"
I will have to repeat this process for All rows....that are imported...
How would I even attempt to to this??
Thanx you...remember..I am a novice and show and tell works best for me...otherwise..I will be lost..

Answer 1

If the order of data is always the same I would doctor the data before importing to remove all the extra stuff that is not numerical values.  e.g.  I would change:
Topogram: kV=120 mAs=130  CHEST: kV=120 mAs=1058 CTDIvol=6.84 DLP=84.82  CHEST: kV=120 mAs=1055 CTDIvol=6.84 DLP=84.82
to:
Topogram: kV, mAs, CHEST: kV, mAs, CTDIvol, DLP, CHEST: kV, mAs, CTDIvol, DLP
120, 130, 120, 1058, 6.84, 84.82, 120, 1055, 6.84, 84.82
For a Numbers solution I would make an table where you paste your CT data and another one the parses out the fields with an area where you can copy the parsed data.  Something like:
What I am showing is:
your original row of data followed by the character location of the equal signs (just count characters starting at the left until you find an equal sign) followed by the location of the space following the equal sign.  followed by the parsed values.
once you know where the "=" and " " are you can pick out the charaters between them... that take characters from:
Character location of "=" + 1 to the next space.
So the formulas are:
B1=SEARCH("=", A1, 1)+1
C1=SEARCH("=", $A$1, B1+1)+1
select C1 and fill to the right until K1
M1=SEARCH("=", $A$1, B1+1)+1
select M1 and fill to right until U1
V1=LEN(A1)+1
X1=MID($A$1, B1,M1-B1)
select X1 and fill to the right until AG1
X1 thru AG1 are the numerical values
you can now copy them to another location by select the range you want then select the destination cell, and select the menu item "Edit > Paste Values"
I hope this helps
