There are several ways to deal with HTML entities.
Simple search & replace
This code allows you to escape your HTML entities with one shortcut key: Change (<, >, &) to (<, >, &), or the reverse.
Note that this does not escape all characters that should be escaped, just the most common.
function HtmlEscape() silent s/&/\&/eg silent s/</\</eg silent s/>/\>/eg endfunction function HtmlUnEscape() silent s/</</eg silent s/>/>/eg silent s/&/\&/eg endfunction map <silent> <c-h> :call HtmlEscape()<CR> map <silent> <c-u> :call HtmlUnEscape()<CR>
If you add this code to your vimrc, you can escape visually-selected HTML with ctrl-h, and unescape with ctrl-u.
There's also script that does this for you automagically when you read and write files, so you can view the characters, and write the codes, or vice versa: script#909.
Originally written for Java unicodes, but there is also a setting for html codes.
The script is for &nnn style encoding, not the html entities.
Does not seem to work with vim 7.1, maybe it can be fixed?
function! HTMLEncode() perl << EOF use HTML::Entities; @pos = $curwin->Cursor(); $line = $curbuf->Get($pos); $encvalue = encode_entities($line); $curbuf->Set($pos,$encvalue) EOF endfunction function! HTMLDecode() perl << EOF use HTML::Entities; @pos = $curwin->Cursor(); $line = $curbuf->Get($pos); $encvalue = decode_entities($line); $curbuf->Set($pos,$encvalue) EOF endfunction map <Leader>h :call HTMLEncode()<CR> map <Leader>H :call HTMLDecode()<CR>
Go to the line and do \h or \H to check it out.
