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>
