Consider a file file.dat
that has a form
...
string 1
x1 y1 z1
x2 y2 z2
...
string 2
...
where x,y,z are numbers.
Could you please tell me how to import only the following strings in the form of numerical data?
x1 y1 z1
x2 y2 z2
...
One way to do it is
str = Import["file.dat", "Text"];
data = StringCases[str, "string 1n" ~~ x___ ~~ "nstring 2" :>
ImportString[x, "Table"]]
This example includes the newline character explicitly. You may or may not want to include one before the first "string" and after the "2". Or, you may want to leave the newline out. Note that some text files may terminate the lines with "rn" instead of just the "n".
