18456 | 9 " Last Change: |
10 " 20190923 - Fix xmlEndTag to match xmlTag (vim/vim#884) | |
11 " 20190924 - Fix xmlAttribute property (amadeus/vim-xml@d8ce1c946) | |
18790 | 12 " 20191103 - Enable spell checking globally |
26708 | 13 " 20210428 - Improve syntax synchronizing |
7 | 14 |
15 " CONFIGURATION: | |
16 " syntax folding can be turned on by | |
17 " | |
18 " let g:xml_syntax_folding = 1 | |
19 " | |
20 " before the syntax file gets loaded (e.g. in ~/.vimrc). | |
21 " This might slow down syntax highlighting significantly, | |
22 " especially for large files. | |
23 " | |
24 " CREDITS: | |
25 " The original version was derived by Paul Siegmann from | |
26 " Claudio Fleiner's html.vim. | |

31 " | |
32 " as <hirauchi@kiwi.ne.jp> pointed out according to reference [1] | |
33 " | |
34 " 2.3 Common Syntactic Constructs | |
35 " [4] NameChar ::= Letter | Digit | '.' | '-' | '_' | ':' | CombiningChar | Extender | |
36 " [5] Name ::= (Letter | '_' | ':') (NameChar)* | |
37 " | |
38 " NOTE: | |
39 " 1) empty tag delimiters "/>" inside attribute values (strings) | |
40 " confuse syntax highlighting. | |
41 " 2) for large files, folding can be pretty slow, especially when | |
42 " loading a file the first time and viewoptions contains 'folds' | |
43 " so that folds of previous sessions are applied. | |
44 " Don't use 'foldmethod=syntax' in this case. | |
45 | |
46 | |
47 " Quit when a syntax file was already loaded | |
48 if exists("b:current_syntax") | |
