. . .

</main>

,whereencoding—coding reference designation applied for text file.

Forfiles MS Windows 95/98/NT/2000/XP: windows-1251,

Record<xxx> is subsequently denominated an opening tag and </xxx> - aclosing tag  xxx. Tag declaration shouldcontain no spaces and tabs. The body between an opening tag  <xxx> and a closing tag  </xxx> is called section xxx.

Thereforeeach file contains a header and a section main. Section main in its turncontains one or more sections insert, update or delete.
