Preg Replace

I have a file with <html><head><meta something...><meta something
else...>. I need to remove that text.

I would use str_ireplace, but the contents of the two metas change
with the file.

I know preg_replace allows you to do that, but how? I have tried to
learn regular expressions, but I am having serious problems doing so.

Thanks in advance.

What you want to do is just removing HTML tags?

$without_meta=preg_replace('/<meta[^>]*>/i','',$with_meta);

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

Indeed, and how many sites have incorrect HTML? A lot more then fully =

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.)
