How to extract info from string using regexp?
显示 更早的评论
I have a text file with a number of lines such as:
[DEBUG][HoraCorrelationMatrixNode] Polygon 2303 id 857befored
[DEBUG][HoraCorrelationMatrixNode] Polygon 2304 id 88befored
[DEBUG][HoraCorrelationMatrixNode] Polygon 2305 id 930befored
[DEBUG][HoraCorrelationMatrixNode] Polygon 2306 id 1000d
[DEBUG][HoraCorrelationMatrixNode] Polygon 2307 id 1001d
I need to extract both polygon number (2303) and its id (857befored). How to write a regular expression pattern to obtain both information?
Thanks

This should work:
filecontent = fileread('c:\somewhere\somefile');
polyid = regexp(filecontent, 'Polygon (\d+) id (\S+)', 'tokens');
polyid = vertcat(polyid{:});
result = table(str2double(polyid(:, 1)), polyid(:, 2), 'VariableNames', {'Polygon', 'ID'})

Hi,
Since all the lines are of same format. I would reccomend you to do something like this
str = ['[DEBUG][HoraCorrelationMatrixNode] Polygon 2303 id 857befored']
Polygon_num = str(45:49)
id_num = str(52:end)
This would be easier to implement
