[Tip] Workaround for incorrectly removed attributes #219
Description
Hi!
I've found several issues here caused by incorrectly removed HTML attributes, and I've recently opened a new one. I'd like to share my workaround, hoping it might be useful to someone, until a better solution is available.
The basic idea is to replace incorrectly removed strings with a unique string sequence and restore them after minification. My example is in Python, but it can be easily adapted to other programming languages.
def unique_id():
# uuid.uuid1() is a function from Python standard
# library that generates unique ids
return str(uuid.uuid1())
strings_to_preserve = [
['target="_self"', unique_id()],
['type="text"', unique_id()]
]
# Replace strings with unique ids that will be preserved
for string, id in strings_to_preserve:
html = html.replace(string, id)
minified = minify_html.minify(html)
# Replace preserved ids with original strings
for string, id in strings_to_preserve:
minified = minified.replace(id, string)I haven't tested this approach beyond attributes, but it should likely work for other cases as well.
