PostgreSQL - Replace HTML Entities

Question

I have just set about the task of stripping out HTML entities from our database, as we do a lot of crawling and some of the crawlers didn\'t do this at input time :(

Answer 1

You could use xpath (HTML-encoded content is the same as XML encoded content):

select 
  'AT&T' as input ,
  (xpath('/z/text()', ('' || 'AT&T' || '')::xml))[1] as output
