This project was developed for the subject of Server-Side Technologies: Cloud Computing as part of the official university master’s degree in Mobile Computing (MIMO).

The main objective was to implement a Java application capable of processing a news channel in RSS (XML) format and generating XML and JSON output files, applying modern processing techniques and specific tools.

Main functionalities

1. XML processing:

Implementation of two versions of RSS file processing:

• DOM (Document Object Model): Loads the entire document into memory and allows structured navigation.
• SAX (Simple API for XML): Sequential reading of the file, more efficient for large volumes of data.

Extraction and presentation of key information:

• From the channel: Title, URL, description.
• From the news: Title, URL, description, publication date and category.

2. Output file generation:

XML: Structured file with the news titles in the format:

1
2
3
4

<news channel="channel title">
    <news>news title 1</news>
    <news>news title 2</news>
</news>

JSON: Equivalent file, generated with the format:

1
2
3
4
5
6

{
    "news": [
        {"news": "news title 1"},
        {"news": "news title 2"}
    ]
}

3. Conversion with GSON:

Use of the GSON library for serialization and deserialization between Java objects and JSON, ensuring simple and efficient data manipulation.
