class IsHtmlValidator(BaseValidator):
    """
    Checks if a value contains valid HTML. The validator looks for
    the presence of HTML tags in the input string.

    **Parameters:**

    - **error_message** (*Optional[str]*): Custom error message if the value
        does not contain valid HTML.

    **Expected Behavior:**

    Verifies that the input is a string and checks for HTML tags using a
    regular expression. Raises a ``ValidationError`` if no HTML tags are found.

    **Example Usage:**

    .. code-block:: python

        class HtmlInputFilter(InputFilter):
            def __init__(self):
                super().__init__()
                self.add('html_content', validators=[
                    IsHtmlValidator()
                ])
    """

        self.error_message = (
            error_message or "Value does not contain valid HTML."

    def validate(self, value: Any) -> None:
        if not isinstance(value, str):
            raise ValidationError("Value must be a string.")

        if not re.search(r"<\s*\w+[^>]*", value):
            raise ValidationError(self.error_message)
