prettierfier

prettierfier

While I love Beautiful Soup as a parser, BeautifulSoup.prettify() adds a linebreak between every tag. This results in unwanted white space between tags that should be inline, like <sup>, <a>, <span>, etc:

<p>Introducing GitHub<sup>&reg;</sup></p>

Introducing GitHub^®

vs.

<p>
    Introducing GitHub
    <sup>
        &reg;
    </sup>
</p>

Introducing GitHub ^®

This module parses HTML/XML as a raw string to more intelligently format tags.

Installation

You have two options:

• pip install prettierfier in your command line
• Copy the contents of prettierfier.py to your own module.

This module is built with just the Python Standard Library and contains no external third-party dependencies.

Functions

prettify_xml(xml_string, indent=2, debug=False)

• Can be used with no prior formatting.

    Args:
        xml_string (str): XML text to prettify.
        indent (int, optional): Set size of XML tag indents.

    Test-only args:
        debug (bool, optional): Show results of each regexp application.

    Returns:
        str: Prettified XML.

prettify_html(html_string, debug=False)

• Originally created to process BeautifulSoup.prettify() output.
• Does not add or remove regular line breaks. Can be used with regular HTML if it already has the newlines you want to keep.

    Args:
        html_string (str): HTML string to parse.

    Test-only args:
        debug (bool, optional): Show results of each regexp application.

    Returns:
        str: Prettified HTML.

Example

import prettierfier

ugly_html = """<p>
    Introducing GitHub
    <sup>
        &reg;
    </sup>
</p>"""

pretty_html = prettierfier.prettify_html(ugly_html)
print(pretty_html) 

# Output
>>> <p>Introducing GitHub<sup>&reg;</sup></p>
