Feature request

Add support to YAML loader in document loaders, similar to JSONLoader .

class YAMLLoader(BaseLoader):
    """Load and parse a YAML file into a Document."""
    
    def __init__(self, file_path: Union[str, Path]):
        """Initialize with the file path."""
        self.file_path = file_path

    def load(self) -> List[Document]:
        # Open the YAML file and load its content
        with open(self.file_path, "r") as file:
            try:
                # Load the YAML content
                data = yaml.safe_load(file)
            except yaml.YAMLError as e:
                print(f"Error loading YAML file {self.file_path}: {e}")
        
        # Define metadata with file path information
        metadata = {"source": str(self.file_path)}
        
        # Return the loaded content as a list of Documents
        return [Document(page_content=text, metadata=metadata)]

Motivation

I was working on a small project and couldn't find a YAML loader in document loaders. Please let me know if we can add this I’d be happy to work on it
