How can I use Apache Tika to extract and process content from different file types within a ZIP archive?

Reading Content from Files in a Zip Archive Using Apache Tika

Problem:
Extract and process the contents of multiple file types (.txt, .pdf, .docx) within a ZIP archive using Apache Tika.

Solution:

1. Create a ZipFile Object:
Instantiate a ZipFile object to represent the ZIP archive and obtain an Enumeration of ZipEntry objects:

<code class="java">ZipFile zipFile = new ZipFile("C:/test.zip");
Enumeration<? extends ZipEntry> entries = zipFile.entries();</code>

2. Iterate through Entries:
Loop through each ZipEntry in the enumeration:

<code class="java">while (entries.hasMoreElements()) {
    ZipEntry entry = entries.nextElement();
}</code>

3. Obtain File Content:
For each ZipEntry, get an InputStream to its content:

<code class="java">InputStream stream = zipFile.getInputStream(entry);</code>

4. Parse File Content using Apache Tika:
Since you're using Apache Tika, create a new Tika instance and use its parsing methods to extract the file content:

<code class="java">Tika tika = new Tika();
String content = tika.parseToString(stream);</code>

5. Process Extracted Content:

<code class="java">// Process your extracted content here...</code>

Notes:

• Using this approach, you can read the content of all supported file types by Apache Tika.
• Remember to handle exceptions that may occur during file processing.
