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.

Rust

let mut success = false;

let zip = chilkat::Zip::new();

// Open an existing ZIP archive.
success = zip.open_zip("c:/temp/sample.zip").is_ok();
if !success {
    println!("{}", zip.last_error_text());
    return;
}

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

success = zip.entry_matching("docs/*", &entry).is_ok();
if !success {
    println!("No matching entries found.");
    zip.close_zip();
    return;
}

// ------------------------------------------------------------
// Iterate through all matching entries.
// 
// GetNextMatch updates the same ZipEntry object so that
// it represents the next matching entry.
// 
while success {
    if entry.is_directory() {
        println!("[Directory] {}", entry.file_name());
    } else {
        println!("[File] {}", entry.file_name());
    }

    // Advance to the next matching entry.
    success = entry.get_next_match("docs/*").is_ok();
}

zip.close_zip();

println!("Done.");
