function suite.makeHtmlPattern(tagTables)
	-- Makes a pattern for use with assertStringContains.
	-- The input is an array of tables, each of which corresponds to an opening tag,
	-- a piece of wikitext, or a closing tag.
	-- 
	-- It is also possible to use a single table as an input, rather than an
	-- array of tables.
	--
	-- Opening tags:
	-- {tag = 'tr'}
	-- {tag = 'table', attr = 'class', value = 'mbox-image'}
	-- {tag = 'table', attr = 'style', property = 'text-align', value = 'center'}
	-- {tag = 'td', attr = 'colspan', value = '3'}
	-- Properties and values are escaped so that hyphens etc. will work in patterns.
	--
	-- Wikitext:
	-- {wikitext = 'Foo'}
	--
	-- Closing tags:
	-- {tag = 'table', close = true}
	--
	-- For Example, this code:
	-- suite.makeHtmlPattern{
	--   {tag = 'div', attr = 'style', property = 'text-align', value = 'center'},
	--   {wikitext = 'Foo'},
	--   {tag = 'span'},
	--   {wikitext = 'Bar'},
	--   {tag = 'span', close = true},
	--   {tag = 'div', close = true}
	-- }
	--
	-- Produces this:
	-- <div[^>]-style="[^">]-text%-align%s*:%s*center[^">]-"[^>]->[^<]-Foo[^<]-<span[^>]->[^<]-Bar[^<]-</span>[^<]-</div>
