Read a file's content in Python|PHP

Question

I have 100+ save file of omnigraffle, need to write a script to read then change its content.

Example one:
https://www.dropbox.com/s/97cec5err3qubgq/test.graffle?dl=0

I can open it by TextMate, file's content is in xml format

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
 <key>ActiveLayerIndex</key>
 <integer>0</integer>
 <key>ApplicationVersion</key>
 <array>
 <string>com.omnigroup.OmniGraffle6</string>
 <string>163.7.0.243167</string>
 </array>
 <key>AutoAdjust</key>
 <true/>
 <key>BackgroundGraphic</key>
 <dict>...

So i write code to read and write that file in Python

contents = open(filename).read()
print contents

Result is

?]Ys?8~N~?֯IxgO?Gbg}?%?;)Wm?$sB
4???=?z?;F.??l??h?O????q??ش7~?z???ݓ???{??s#?8=?><?il4??Nx?????6N??o???;?hl?0?o????[XP???VF?Ӑ$d????&?????&i=????????o6??ǭN??w???????Ͷ?+/t}FF$?????

????{?l?????h????]?7.?y?]7 ?&?

So how can we read that file in Python/PHP?

• tmthydvnprt: seems like you need to mess with string encoding

Answer 1

The file in the link you give is compressed with gzip, either as it is stored, or compressed by dropbox when being downloaded to save space.

Either run the gunzip command on the file before using it, or use the python gzip module:

import gzip
with gzip.open(filename) as f:
 contents = f.read()
