Thanks in advance.

What you want to do is just removing HTML tags?

Whoops...

Incorrect HTML.
Here must be <meta name="descripti on" content="This has a tag">

Incorrect HTML.
Here must be <meta name="descripti on" content="This has a 
tag">

Indeed, and how many sites have incorrect HTML? A lot more then fully
valid ones... Which is why I'm going te repeat the mantra: "Use a parser
for HTML manipulation or inspectation, not Regex". DOM comes to mind, very
nice package.

I think I am in big trouble: sometimes I use Regex-based parser, for
HTML too. :) I know about problem with incorrect attributes and can
write regexp to deal with it. Yes, this is much more easy to load file
into DOM document using loadHTML() then to write complex regexp dealing
with all these incorrect cases.

No it isn't.

(Yet *another* reason not to reinvent this particular wheel.)

Incorrect HTML.
Here must be <meta name="descripti on" content="This has a tag">

According to standard, you do not need to escape ">", only "<".

Wrong (again). That's why there is > Otherwise the <meta tag may
end prematurely.

I don't know what "standard" you are talking about, but the HTML
specification allows both "<" and ">" in the content attribute.
Content is defined as CDATA, so pretty much anything goes. If you are
talking about the XHTML specification, then yes, "<" needs to be
escaped but ">" doesn't.
