I'm parsing a text file to extract word definitions. For example the
input text file contains the following content:
di.va.gate \'di_--v*-.ga_-t\ vb
pas.sim \'pas-*m\ adv : here and there : THROUGHOUT
I am trying to obtain words between two literal backslashes (\ .. \). I
am not able to match words between two literal backslashes using the
regxp - re.compile(r'\\[^\\]*\\').
Here is my sample script:
import re;
#slashPattern = re.compile(re.escape(r'\\[^\\]*\\'));
pattern = r'\\[^\\]*\\'
slashPattern = re.compile(pattern);
fdr = file( "parseinput",'r');
line = fdr.readline();
while (line != ""):
if (slashPattern.match(line)):
print line.rstrip() + " <-- matches pattern " + pattern
else:
print line.rstrip() + " <-- DOES not match pattern " +
pattern
line = fdr.readline();
print;
----------
The output
C:\home\krishna\lang\python>python wsparsetest.py
python wsparsetest.py
di.va.gate \'di_--v*-.ga_-t\ vb <-- DOES not match
pattern \\[^\\]*\\
pas.sim \'pas-*m\ adv : here and there : THROUGHOUT <-- DOES not match
pattern \\[^\\]*\\
-----------
What should I be doing to match those literal backslashes?
Thanks
