Searching multiple Strings in file

Hi,

The typical file format is as follows:

channelCfg 15 3 0
adcCfg 2 1
adcbufCfg -1 0 0 1 0

The text file is read. The keywords are adcCfg and adcbufCfg. Searching for the keywords only integers in that line have to be stored in a vector. I tried to get something to work with regexp and strfind but got no satisfying results.

Regards

but got no satisfying results

And what is a statisfying result?

Is this what you're after?

filecontent = fileread('c:\somewhere\somefile.txt');
adclines = regexp(filecontent, '(?<=adc(buf)?Cfg).*', 'match', 'dotexceptnewline');
adcnumbers = cellfun(@str2double, regexp(adclines, '[+-]?\d+', 'match'), 'UniformOutput', false);
celldisp(adcnumbers)

Thanks for your help. This does the job.

Alternatively multiple expressions are added with or: '|'.

Regexp at first appears to be very convenient but also not intuitive.

"Regexp at first appears to be very convenient but also not intuitive."

You will get used to them. It takes a lot of reading the documentation to use regular expressions effectively. This is your source of information:

not intuitive

Like any language, you have to learn it. It is very self-consistent and once you know it very intuitive.

Alternatively multiple expressions are added with or: '|'.

I'm not sure why you are mentioning this.

Is your question answered then?
