How to decode html encoded text in sql server? (or ms access!)

问题:

I have a column with text in the following format...

sweet shop

is there a way to convert this directly to it's corresponding text in sql server? (it is actually a linked ms access database so I could also use access too!)

(I think this format is also called Numeric character reference and contains the code points of unicode characters)

回答1:

Alex K is 99.99% correct, however the conversion would fail if you had Named Codes like   or £

So, here we perform a brute force replace, and then parse the string via XML

Example

Returns

回答2:

Here is a much easier way to decode HTML-encoded strings:

It requires SQLHTTP which is a free database/assembly that we created which you can find on our website at: http://sqlhttp.net/documentation/encoding/htmldecode/

SELECT SQLHTTP.net.HtmlDecode('sweet shop')

and the result is as expected:

------------- sweet shop  (1 row affected)
