If your XML entities are included in the file you are just editing, Vim
can auto-complete their names for you - just write the
initial& and press the omni-completion shortcut
(+
if you followed me recently).
If XML entities are included from other file, Vim cannot see it. You
have to convert the entity file into .vim format and
include it into the vimxmlentities option in the
current Vim DTD file, such as
~/.vim/autoload/xml/docbook5.vim.
To ease this process, I included the
update_docbook_entities.pl script. It takes your
custom entity file as a first argument, and the DTD .vim file as a second
argument. It extracts found entities, converts them into Vim
understandable format, and adds them into the custom DTD file, such as
docbook5.vim.
To add a shortcut to this script to Vim, add (and customized) this line
to your .vimrc file:
nnoremap <silent> _e :!update_docbook_entities.pl xml/entity-decl.ent ~/.vim/autoload/xml/docbook5.vim<CR><CR>
This line ensures—assuming that you moved
update_docbook_entities.pl to $PATH—that after
pressing _e, the entities found in the
xml/entity-decl.ent file will be added to
~/.vim/autoload/xml/docbook5.vim.
