You are given a code snippet that contains some syntax errors and poorly written code. Your task is to analyze the code and fix the issues. Additionally, you need to explain the purpose of the code and provide a detailed explanation of the fixed code.

The code snippet provided is as follows:

```
if 'id' not in str(__InFo):
    pass
else:
    try:
        users.append(str(__InFo['slug']))
    except:
        pass

except:
    pass

if not len(users) == 0:
    pass
else:
    try:
        GETSource3 = session.get('http://' + site + '/author-sitemap.xml', timeout=7, headers=Headers)
```

Your task is to:

1. Identify and explain the issues with the code.
2. Fix the code by resolving the syntax errors and improving the code structure.
3. Explain the purpose of the code and provide detailed explanations for the fixed code.

Sure, I'd be happy to help with this task.

1. **Issue**: The first `if` statement checks if 'id' is not in the `__InFo` string. However, `__InFo` is passed as a function argument and is not easily accessible. It's also unclear how the value of `str(__InFo)` will be used in the following lines.

   **Fixed**: We can change the first `if` condition to a more meaningful and specific check. For example, we could check if 'slug' is in `__InFo`, which suits the second `if` condition to append the slug.

   ```python
   if 'slug' not in __InFo:
       pass
   else:
       users.append(__InFo['slug'])  # Important: Note the use of a dictionary-like object for the 'slug' value.
   ```

2. **Issue**: The `try...except` block around `users.append(str(__InFo['slug']))` is unnecessary. Besides, the `str()` is a type conversion built-in function and doesn't need to be wrapped in a `try` block.

   **Fixed**: Removing the `try...except` block and type conversion.

   ```python
   if 'slug' in __InFo:
       users.append(__InFo['slug'])
   ```

3. **Issue**: The `try...except` block around `GETSource3` is not as helpful as it could be. It's best to use `response.status_code` and `response.raise_for_status()` method to handle 4xx and 5xx responses.

   **Fixed**: In this example, the `response` object is not assigned before the `raise_for_status()` call. Also, `timeouts` is set to 7 seconds, but the method will halt after 1 second by default. Finally, `raise_for_status()` will raise an exception if the response is not a 2xx status code.

   ```python
   response = session.get('http://' + site + '/author-sitemap.xml', timeout=7, headers=Headers)

   if response.status_code in [200, 201]:
       pass
   else:
       response.raise_for_status()
       print('Error: Status Code {}, URL: {}'.format(response.status_code, response.url))
   ```

4. **Explanation**: In this code, we could be fetching author data using a sitemap. The first `if` statement checks whether a 'slug' is present in `__InFo` (a dictionary-like object). If no, it moves on since we're only appending slugs. Then it tries to append a slug for each user if available.

   The last block is fetching the XML-like response, raising an error if the response is not 'OK' (2xx), checking whether response exists, and printing the error. **Note:** It's critical to notice that some sites may return partially filled sitemaps, or the sitemap file has no code for fetching data.

   These aims, of course, are for the given snippet, and you may add or move blocks by your context.

1. Issues with the code:

   a) The variable `__InFo` is not defined anywhere in the code. It is being used without any prior declaration or assignment.

   b) The first `except` block is not associated with any `try` block, resulting in a syntax error.

   c) Using a generic `except` clause without specifying the exception type is considered a bad practice, as it can hide actual errors and make debugging difficult.

   d) The use of `if not len(users) == 0` can be simplified to `if not users`.

   e) The variable `GETSource3` is being assigned the result of an API call, but it is not being used anywhere else in the code.

2. Fixed and improved code:

```python
# assuming __InFo is a dictionary and users is an empty list defined earlier in the code

if 'id' not in __InFo:
    pass
else:
    try:
        users.append(__InFo['slug']) # no need to convert 'slug' to str if it's already a string
    except KeyError as e:
        print(f"KeyError: {e}")

if not users: # check if users list is empty
    try:
        GETSource3 = session.get(f'http://{site}/author-sitemap.xml', timeout=7, headers=Headers)
        # do something with GETSource3, e.g., store it, process it, or return it
    except Exception as e:
        print(f"Error while fetching author sitemap: {e}")
```

3. Purpose and explanation of the fixed code:

The given code checks if a specific key ('id') exists in the `__InFo` dictionary. If it exists, it attempts to append the value associated with the 'slug' key from the same dictionary to the `users` list. If any KeyError occurs during this process, it catches the exception and prints an error message.

If the `users` list is empty (no slugs appended), the code makes a GET request to fetch the content of the author sitemap XML from a URL constructed using the `site` variable and stores the response in the `GETSource3` variable. If there's an issue with the GET request, it catches the exception and prints an error message.

The code's purpose seems to be gathering slugs from a dictionary and, if there are no slugs, fetching an author sitemap XML from a given URL. However, to fully understand and properly utilize the code, more context or additional code snippets would be required.
