Find part of string and remove entire line

Hi,

I have a text file that looks like this 'textfile.txt':

'Algorithm: G:\folder: Example'

'2013-May-30 20:46:10'

'QAdR = 123678'

'QaDB = 9098'

'This is what I wanted'

How do i find all the special characters ':' & '=' and remove the entire row containing ':' & '=' and write it to 'textfile.txt'. My new 'textfile.txt' should only contain 'This is what I wanted'.

Hi, probably start by reading in the text file

filename='textfile.txt';
f=fopen(filename);
line1=fgetl(f);

Then you could check each line with a regexp and save it if it does not contain your characters.

if isempty(regexp(line1,'[:=]'))
    ...% save your line
end

and build a new text file from there.

Hope this helps as a start at least.
