SED - Create mailto: link

I am using sed to convert text files into easily viewed html tables.
I have managed all except converting the email addresses to mailto: links.
Multiple email addresses exist within the files, either preceded by a space or > (as part of HTML tag), and followed by either space or <
I've tried various things based around the below, but nothing seems to work.
sed -e "s|\w+@\w+\.\w+(\.\w+)?|<a href=\"mailto:\0\">\0</a>|g" nolinks.html > links.html

I am using super-sed 3.62 on an XP machine. (Sorry!!)

Can anyone please help?

Can you post sample email addresses and the required output format..?
Please wrap your sample files/lines within the CODE tag-icon available in the tool bar while posting reply.

Thanks for your quick response.
mail addresses will be from domains such as,
users could be name@ or firstname.lastname@. it is unlikely that anyone would have an apostrophe in the name.
For example: the text would be converted to <A HREF=""></A> in the output file.

echo '' | sed -n 's|[^ ]*@[^ ]*|<A HREF="mailto:&">&</A>|gp'

If the above did not help post few lines of your HTML file.

Due to the limitations of the windows version needing double quotes I substituted:
echo | sed -n "s|[^ ]*@[^ ]*|<A HREF=\"mailto:&\">&</A>|gp"

This returned sed: -e expression #1, char 30: unterminated `s' command

The working command I use to create hyperlinks is
sed -e "s|http[:]//[^<]*|<a href=\"\0\" style=\'text-decoration: none; color: blue; font-weight: bold;\'>\Details Here</a>|g" table.html > newtable.html

so I know that \" works within the command.

From a typical file:

Sorted it!

I found the solution at

Supported for -r (extended regex) or -R (Perl-mode). NOTE: the -r
switch is an undocumented option in GNU sed v3.02+.
adding the -r switch to my original code gave the working solution

Thanks for your time and help.
