## 範例

以下範例掃描現有 zip 存檔，並不斷向輸出資料追加存檔中每個檔案和目錄的資訊。掃描完所有檔案和目錄後，資料將作為輸出檔案推送。

```xml theme={null}
<!-- Creating the input item and the necessary attributes -->
<arc:set attr="zip.archive" value="C:\\Temp\\test.zip" />
<arc:set attr="zip.type" value="ZIP" />
<!-- Initializing the output data -->
<arc:set attr="output.data" value="" />

<arc:call op="zipScan" in="zip" out="results">
  <!-- Appending the information of each file and folder to the output data -->
  <arc:set attr="output.data" value="[output.data]\nThe file [results.zip:filename] has a compressed size of [results.zip:compressedsize] bytes and an uncompressed size of [results.zip:decompressedsize] bytes. The last modified time is [results.zip:lastmodified]." />
</arc:call>

<!-- Pushing the output item out as a file -->
<arc:set attr="output.filename" value="result.txt" />
<arc:push item="output" />
```
