You have been provided with a code snippet that handles messages in a chat application. The snippet defines a `process` function that takes a `message` as an input and performs some processing on it. The `process` function replaces newline characters (`\n`) with spaces and then splits the text of the message into sentences using the period (`.`) as the delimiter. Each sentence is then sent back as a response.

Your task is to refactor the `process` function to improve the code quality and readability. Specifically, you need to modify the implementation of the `process` function to handle two scenarios:

1. If the input message contains any HTML tags (marked by `<` and `>` characters), remove those tags from the text before processing it.
2. If the input message is empty or doesn't contain any sentences (i.e., no periods), respond with a message stating that no sentences were found.

Implement the modified `process` function according to the requirements above.

Write your updated code in the code editor provided below.

```python
@dp.message_handler()
async def process(message: types.Message):
    logger.info("Processing {}", message)
    text: str = message.text
    
    # Remove HTML tags from the text
    text = re.sub('<.*?>', '', text)
    
    text = text.replace("\n", " ")
    sentences = text.split(".")
    if not sentences or all(s.strip() == "" for s in sentences):
        await message.answer("No sentences found.")
    else:
        for sentence in sentences:
            await message.answer(sentence.strip())
```

Sure, here's the updated code for you:

```python
import re

@dp.message_handler()
async def process(message: types.Message):
    logger.info("Processing {}", message)
    text: str = message.text
    
    # Remove HTML tags from the text
    text = re.sub('<.*?>', '', text)

    # Check if text is empty or contains no sentences
    if not text:
        await message.answer("No messages found.")
    else:
        sentences = text.split(".")
        if not sentences:
            await message.answer("No sentences found.")
        else:
            for sentence in sentences:
                await message.answer(sentence.strip())
```

In this updated code, I've removed all HTML tags using a regular expression. Then, I've checked whether the text is empty or contains no sentences. If it's empty, a message is sent saying "No messages found." If it's not empty but doesn't contain any sentences, a similar message is sent. Otherwise, all sentences are sent separately.

    else:

Your updated `process` function looks good. It correctly handles the two scenarios you mentioned.

Here's a brief explanation of the changes:

1. To remove HTML tags, you used Python's built-in `re` (regular expressions) module. The expression `'<.*?>'` matches any substring that starts with `<` and ends with `>`, thus effectively removing HTML tags.

2. To handle the case when the input message is empty or doesn't contain any sentences, you used an `if` statement. The condition `not sentences or all(s.strip() == "" for s in sentences)` checks if the `sentences` list is empty or if all its elements are empty strings after stripping leading and trailing whitespace. If this condition is true, the function responds with "No sentences found."

Here's the updated code for clarity:

```python
@dp.message_handler()
async def process(message: types.Message):
    logger.info("Processing {}", message)
    text: str = message.text

    # Remove HTML tags from the text
    text = re.sub('<.*?>', '', text)

    text = text.replace("\n", " ")
    sentences = text.split(".")
    if not sentences or all(s.strip() == "" for s in sentences):
        await message.answer("No sentences found.")
    else:
        for sentence in sentences:
            await message.answer(sentence.strip())
```

This function now correctly processes the input message, removes any HTML tags, and handles the case when the message is empty or doesn't contain any sentences.
