使用正则表达式删除python中标签之间的内容

Question

I was trying to clean up wikitext. Specifically I was trying to remove all the {{.....}} and <..>...</..> in the wikitext. For example, for this wikitext:

"{{Infobox UK place\\n|country = England\\n|official_name = Morcombelake\\n|static_image_name = Morecombelake from Golden Cap - geograph.org.uk - 1184424.jpg\\n|static_image_caption = Morcombelake as seen from Golden Cap\\n|coordinates = {{coord|50.74361|-2.85153|display=inline,title}}\\n|map_type = Dorset\\n|population = \\n|population_ref = \\n|shire_district = [[West Dorset]]\\n|shire_county = [[Dorset]]\\n|region = South West England\\n|constituency_westminster = West Dorset\\n|post_town = \\n|postcode_district = \\n|postcode_area = DT\\n|os_grid_reference = SY405938\\n|website = \\n}}\\n'''Morcombelake''' (also spelled '''Morecombelake''') is a small village near [[Bridport]] in [[Dorset]], [[England]], within the ancient parish of [[Whitchurch Canonicorum]]. [[Golden Cap]], part of the [[Jurassic Coast]] World Heritage Site, is nearby.{{cite web|url= http://www.nationaltrust.org.uk/golden-cap/|title=Golden Cap|publisher=National Trust|accessdate=2014-05-04}}\\n\\n== References ==\\n{{reflist}}\\n\\n{{We st Dorset}}\\n\\n\\n{{Dorset-geo-stub}}\\n[[Category:Villages in Dorset]]\\n\\n== External Links ==\\n\\n*[ http://www.goldencapteamofchurches.org.uk/morcombelakechurch.html Parish Church of St Gabriel]\\n\\n"

How can I use regular expressions in python to produce output like this:

\\n'''Morcombelake''' (also spelled '''Morecombelake''') is a small village near [[Bridport]] in [[Dorset]], [[England]], within the ancient parish of [[Whitchurch Canonicorum]]. [[Golden Cap]], part of the [[Jurassic Coast]] World Heritage Site, is nearby.\\n\\n== References ==\\n\\n\\n\\n\\n\\n\\n[[Category:Villages in Dorset]]\\n\\n== External Links ==\\n\\n*[ http://www.goldencapteamofchurches.org.uk/morcombelakechurch.html Parish Church of St Gabriel]\\n\\n

Answer 1

As the tags are nested into each other, you can find and remove them in a loop:

n = 1
while n > 0:
    s, n = re.subn('{{(?!{)(?:(?!{{).)*?}}|<[^<]*?>', '', s, flags=re.DOTALL)

s is a string containing the wikitext.

There are no the <...> tags in your example, but they should be removed as well.
