Function to replace characters with HTML character references ( < > )?

[alpine]

I'm looking into the fpc packages for such a function but I can't find one.
There should be one somewhere (fcl-web), with such a developed infrastructure...

unit
httpprotocol

has a httpdecode and httpdecode function

any use ?

Found these but they are for URL encoding (+%xxx+).

EscapeHTML() and  UnescapeHTML() routines are located in htmlelements.pp in the fcl-xml package.

EscapeHTML can only handle ampersand, less than, greater than, inch sign, and dumb apostrophe, yet there are 1926 character entities. I don’t think Alpine would’ve asked his question if all he needed was escaping the special meaning characters ampersand and less than sign. He could’ve accomplished that on his own.

It's hard to answer a question that was not asked...

Take a look at https://www.benibela.de/documentation/bbutils/bbutils.html#strDecodeHTMLEntities
Its missing fpc functions
But we need to solve the opposite problem.
Benny's methods are quite complex and close to black magic, but here I laid out a principle that can be easily reversed

There are 2231 entities )))

P.S. It's the only place I know that is close to what you are looking for
https://gitlab.com/freepascal.org/lazarus/lazarus/-/blob/main/components/lazutils/html2textrender.pas#L293
But there's only 3! entities in the function

@Kays
Wow, I didn't knew they are so many. I've expected something in the hundreds.

@dsiders
Thank you for pointing me to fcl-xml.

Meanwhile, I really wrote a one-liner stub which happens to be just like the one in the htmlelements.pp. Just hoped for something more comprehensive.
