Question

I need to open an manifest.v3 file and read the version field (xml file), and to do that I’m using the following code:

from zipfile import ZipFile
zf = ZipFile("somezip.zip")
for name in zf.namelist():
    if name.find("manifest.v3")  >= 0:
        for line in zf.read(name).split("\n"):
            for match in  re.findall(r'<value name="version">([0-9].*?)</value>',line):
                parts=match.split(".")
                localVersion=parts[1]
                print localVersion
zf.close()

The code above works good, but sometimes on the zipfile i have the manifest.v3 file and manifest.v3.old, manifest.v3.old.old and so on.

How can I guarantee that I only get the result of the manifest.v3 file? instead all others?

Answer 1

try by changing the condition name.find("manifest.v3") >= 0 to name == "manifest.v3"

Added a few examples below

In [181]: name = "manifest.v3"

In [182]: name.find("manifest.v3") >= 0
Out[182]: True

In [183]: name = "manifest.v3.old.old"

In [184]: name.find("manifest.v3") >= 0
Out[184]: True

In [185]: name == "manifest.v3"
Out[185]: False

In [186]: name = "manifest.v3"

In [187]: name == "manifest.v3"
Out[187]: True
