HTML "sanitizer" in Python

[Scott Stirling]

On opening files in Windows--I was hoping there was a way to give python the full file path.  Everything I have seen so far just tells me how to open a file if it's in the same directory I am running python from.

I don't have sed on my MS Windows PC at work.  This was part of the initial explanation--I am working for a company where we have DOS, Windows and Office 97.  No sed, no Unix.  This is a Y2K Project too, so we are on a budget with little leeway for new ideas that weren't included in the original statement of work and project plan.

??? I don't think it's different on windows than on linux.
Just do:

f = open("my_file.html", "rt")

(OK, there *is* a difference, I guess; you really need the "t" in "rt".
 Otherwise the carriage returns show up in your file.)

Check out the "string" module.

Well you open a second file, for writing this time:
  f2 = open("output.html", "wt")

Then you write to it to your heart's content:
  f2.write("blahblahblah")

Then you close it:
  f2.close()

But all this is in the Python docs, so perhaps you should try to read them.

Well, if I understand correctly, the *only* thing you're trying to do
is to remove some specific strings from a bunch of files. Now if I
were you, I wouldn't even bother to use Python on something that
simple; I would just use sed. With sed, you could do:

  sed 'g/string_to_be_eliminated//g' my_file.html > output.html

Presto, that's it.  I think that there is a version for GNU sed for
Windows somewhere out there; do yourself a favour and get it.
