Add prefix to audio path (.lift)

This script iterates a .lift export and modifies the href attribute of every media tag. This is where paths to audio files are stored.

Setup

The modification consists of adding a prefix to the path. Edit the variables PREFIX and TARGET in the script. It is very easy to implement other modifications using this as a basis (modifying attributes of entities).

Requirements:

pip install beautifulsoup4

Execution

python fix_audio_path.py

Changing file-1.wav to:
/home/audio/file-1.wav
...
