Finding and using the value next to a specific word in a text file!

Hi everybody! I need to find the value of a specific variable printed in a MSC Nastran output file, which is not organized in a complete matrix. Although there isn't a unic organization, (only) the data rows of the file are organized in columns with a fixed width. The following is an extract of my file:

 TRIM ALGORITHM USED: LINEAR TRIM SOLUTION WITHOUT REDUNDANT CONTROL SURFACES.                                           

                                                      AEROELASTIC TRIM VARIABLES
                                  ID     LABEL                 TYPE        TRIM STATUS      VALUE OF UX

                                         INTERCEPT          RIGID BODY           FIXED      1.000000E+00
                                   1     ANGLEA             RIGID BODY            FREE      1.092527E-02  RADIANS         
                                   2     PITCH              RIGID BODY           FIXED      0.000000E+00  NONDIMEN. RATE  
                                   3     URDD3              RIGID BODY           FIXED     -9.810000E+00  LENGTH/S/S

For example, if i need to find the value associated to ANGLEA, i suppose to search the number of the row containing the string "ANGLEA (every spaces) RIGID BODY" (i'm including also the second column to avoid multiple results of searching), take it as string, and take from that string the components related to the value; for example:

val = numstr(93:104); % component from 93 to 104 of the string found in the search step
val =

     1.092527E-02

Is it possible to obtain something like that? Or there are more efficient ways? thank you very much for your help!!!
