| 10 " CONFIGURATION: | |
| 11 " syntax folding can be turned on by | |
| 12 " | |
| 13 " let g:xml_syntax_folding = 1 | |
| 14 " | |
| 15 " before the syntax file gets loaded (e.g. in ~/.vimrc). | |
| 16 " This might slow down syntax highlighting significantly, | |
| 17 " especially for large files. | |
| 18 " | |
| 19 " CREDITS: | |
| 20 " The original version was derived by Paul Siegmann from | |
| 21 " Claudio Fleiner's html.vim. | |
| 22 " | |
| 23 " REFERENCES: | |
| 24 " [1] http://www.w3.org/TR/2000/REC-xml-20001006 | |

| 27 " as <hirauchi@kiwi.ne.jp> pointed out according to reference [1] | |
| 28 " | |
| 29 " 2.3 Common Syntactic Constructs | |
| 30 " [4] NameChar ::= Letter | Digit | '.' | '-' | '_' | ':' | CombiningChar | Extender | |
| 31 " [5] Name ::= (Letter | '_' | ':') (NameChar)* | |
| 32 " | |
| 33 " NOTE: | |
| 34 " 1) empty tag delimiters "/>" inside attribute values (strings) | |
| 35 " confuse syntax highlighting. | |
| 36 " 2) for large files, folding can be pretty slow, especially when | |
| 37 " loading a file the first time and viewoptions contains 'folds' | |
| 38 " so that folds of previous sessions are applied. | |
| 39 " Don't use 'foldmethod=syntax' in this case. | |
| 40 | |
| 41 | |
| 42 " Quit when a syntax file was already loaded | |
| 43 if exists("b:current_syntax") | |
| 44 finish | |
