Hi ZyX,

Thank you for all, I have applied this code finally :

import os, fnmatch, re, vim

.. some functions

myListOfFiles = findFiles(topdir, fileExtens)
myDict = findPatternInFile(myListOfFiles, r'^[^>]+KEYWORD')


qflist = []
for filepath in myDict.keys():
for line in myDict[filepath]:
print filepath + " line " + '{:>5}'.format(str(line[0])) + " : " + line[1]
qflist.append({'filename': filepath, 'lnum': line[0], 'text': line[1]})

vim.Function('setqflist')(qflist)
