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.

Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

set zip = CreateObject("Chilkat.Zip")

' Open an existing ZIP archive.
success = zip.OpenZip("c:/temp/sample.zip")
If (success = 0) Then
    outFile.WriteLine(zip.LastErrorText)
    WScript.Quit

success = zip.EntryMatching("docs/*",entry)
If (success = 0) Then
    outFile.WriteLine("No matching entries found.")
    zip.CloseZip 
    WScript.Quit
End If

    If (entry.IsDirectory = 1) Then
        outFile.WriteLine("[Directory] " & entry.FileName)
    Else
        outFile.WriteLine("[File] " & entry.FileName)
    End If

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

zip.CloseZip 

outFile.WriteLine("Done.")
