My previous question asked how to read a file into a strcuture
a line at a time. Figured it out. Now I'm trying to use .find
to separate out the PDF objects. (See code) PROBLEM/QUESTION:
My call to lines[i].find does NOT find all instances of endobj.
Any help available? Any insights?
#!/usr/bin/python
inputfile = file('sample.pdf','rb') # This is PDF with which we
will work
lines = inputfile.readlines() # read file one line at a time
linestart = [] # Starting address for each line
lineend = [] # Ending address for each line
linetype = []
print len(lines) # print number of lines
i = 0 # define an iterator, i
addr = 0 # and address pointer
while i < len(lines): # Go through each line
linestart = linestart + [addr]
length = len(lines[i])
lineend = lineend + [addr + (length-1)]
addr = addr + length
i = i + 1
i = 0
while i < len(lines): # Initialize line types as
normal
linetype = linetype + ['normal']
i = i + 1
i = 0
while i < len(lines): #
if lines[i].find(' obj') > 0:
linetype[i] = 'object'
print "At address ",linestart[i],"object found at line ",i,": ",
lines[i]
if lines[i].find('endobj') > 0:
linetype[i] = 'endobj'
print "At address ",linestart[i],"endobj found at line ",i,": ",
lines[i]
i = i + 1
