I wish to fetch raw wikitext from a selection of webpages (which may be generated using MediaWiki or not).

I try to programmically look through the HTML of a webpage, determine if it uses MediaWiki and fetch raw wikitext, else skip. So far it seems MediaWiki pages tend to have:

• a <meta> tag with name=generator and content=MediaWiki...
• a “Powered by MediaWiki” image in the footer, so look for <img> tag with alt=Powered by MediaWiki

Is this a good approach to look for one of these and try fetching raw wikitext using query param action=raw or is there a better way to do this?

Thanks
