[Scilab-users] Regex problem

[Gerhard Kreuzer]

Hi Jan,

 

that is a nice idea, basically.

The meta data (= ascii) coming first and after that I have binary data.

Now I can read character by character, as you did and stop at the first non ascii character.

Now I only have ascii characters in my strData variable and regex should work.

And this method automatically adapt itself to any length of meta data, so this also works for  me. The length of  the binary data block can be calculated from the meta data and this way I found the next starting point for  the next meta data block.

 

I immediately start coding …

 

Thanks

 

With best regards

 

Gerhard

Would this work? Read as much as you need as binary and convert the non ascii values to an ascii value, for instance 0. 

The below is not optimized, and I have no idea why the strsplit is needed, but I got an "unknown error" without it:

fid=mopen(datafile,"rb");
btr=1000;
B=mgeti(btr+1,"uc",fid);
for i=1:btr+1
        if B(i)>128 | B(i)<32 then B(i)=48; end
end
S=strsplit(ascii(B),btr);
strData=S(1);

[dataStart,dataEnd,dataMatch,data]=regexp(strData,'/#data#/') 
...
