MATLAB: Modify Strings in cell array

cell string removeMATLABregexp

Hi,

I have a cell array:

b = { 'a/b/c/a';  'k/b' ; 'c/c/d' }

I want to remove the string before the first slash.

The result should be:

b = { 'b/c/a';  'b' ; 'c/d' }

How can I achieve the result?

regexprep(b,'[^/]*/', '', 'once')

The pattern translates as "at least two characters, possibly followed by another character, followed by the reverse of the original characters.

The optional middle character handles odd-length cases such as aboba while still permitting even length ones such as abooba.

If the original input were not restricted to 2 or more characters then the pattern would match double letters such as the rr in lorry as that would be character that does not happen to be followed by a second character, followed by the reverse of the first (which would just be itself.) I presume that the problem statement says that those are not to be found. The restriction to 2 or more also has the effect of eliminating cases such as bib so I have to presume that the problem statement says not to find those.

scrubbed = regexprep(YourTable.VariableName, {'^([^/]*/){2}\s*', '\s*/.*$'}, {'',''}, 'once', 'lineanchors', 'dotexceptnewline');

This code does not remove the spaces within the url. Doing that would certainly be possible:

scrubbed = regexprep(YourTable.VariableName, {'^([^/]*/){2}\s*', '\s*/.*$', '\s+'}, {'','',''}, 'lineanchors', 'dotexceptnewline');
