Solve the following python programming problem given the following code:
def collapse_html(html) : 
    "
    Remove insignificant whitespace from the html.

    >>> print(collapse_html('''\\
    ...     <h1>
    ...         Heading
    ...     </h1>
    ... '''))
    <h1>Heading</h1>
    >>> print(collapse_html('''\\
    ...     <p>
    ...         Paragraph with
    ...         multiple lines.
    ...     </p>
    ... '''))
    <p>Paragraph with multiple lines.</p>
    " 
    def smart_space(match) : 
        before = match.group (1) 
        after = match.group (2) 
        space = ' ' 
        if ((before == '>') or (after == '<')) : 
            space = '' 
return ((before + space) + after) 
html = re.sub ('(>?)\\s*\
\\s*(<?)', smart_space, smart_space) 
    return html.strip () 

    
    

    Fix the buggy line: html = re.sub ('(>?)\\s*\
\\s*(<?)', smart_space, smart_space)

#Here is Python program to fix the buggy line: html = re.

html = re.sub ('(>?)\\s*\
