# XML Processor
This script is a Python application for processing XML files. It computes perplexity on sentences and segments in the XML files using the XLM-Roberta model from Hugging Face's transformers library. 
The perplexity scores are then added as new attributes in the XML files.

1. Create a Python virtual environment.
    ```bash
    python3 -m venv .venv
    ```
2. Activate the virtual environment.
    ```bash
    . .venv/bin/activate
    ```
3. Install the required dependencies.
    ```bash
    pip install -r requirements.txt
    ```

## Usage
```bash
python xml_processor.py --input_dir <input_dir> --output_dir <output_dir> [--cpu]
```

* `input_dir`: Input directory containing XML files.
* `output_dir`: Output directory to save processed files.
* `cpu`: (Optional) Add this flag to force the script to use the CPU. If not provided, the script will use the GPU if available.
