Iterate Through Matching ZIP Entries Using EntryMatching and ZipEntry.GetNextMatch

See more Zip Examples

This example demonstrates how to iterate through ZIP entries matching a wildcard pattern using:

• Zip.EntryMatching to obtain the first matching entry
• ZipEntry.GetNextMatch to advance to subsequent matching entries

The wildcard character * matches zero or more characters. Matching is performed against the full stored ZIP entry path.

The example searches for all entries beneath the docs/ directory.

Suppose the ZIP archive contains:

docs/
docs/readme.txt
docs/manual.pdf
docs/sub1/notes.txt
images/logo.png
hello.txt

The wildcard pattern:

docs/*

Matches:

docs/
docs/readme.txt
docs/manual.pdf
docs/sub1/notes.txt

Note that ZIP archives may optionally contain separate directory entries. Therefore, the first matching entry may be the directory entry docs/ rather than a file entry.

CkPython

import sys
import chilkat

success = False

zip = chilkat.CkZip()

# Open an existing ZIP archive.
success = zip.OpenZip("c:/temp/sample.zip")
if (success == False):
    print(zip.lastErrorText())
    sys.exit()

# ------------------------------------------------------------
# Find the first ZIP entry matching the wildcard pattern:
# 
#     docs/*
# 
# Matching is performed against the full stored ZIP path.
# 
entry = chilkat.CkZipEntry()

success = zip.EntryMatching("docs/*",entry)
if (success == False):
    print("No matching entries found.")
    zip.CloseZip()
    sys.exit()

# ------------------------------------------------------------
# Iterate through all matching entries.
# 
# GetNextMatch updates the same ZipEntry object so that
# it represents the next matching entry.
# 
while (success == True) :
    if (entry.get_IsDirectory() == True):
        print("[Directory] " + entry.fileName())
    else:
        print("[File] " + entry.fileName())

    # Advance to the next matching entry.
    success = entry.GetNextMatch("docs/*")

zip.CloseZip()

print("Done.")
