I have devised a simple mark-up scheme for my own purposes which is much simpler than XML.
If you have ever looked at the official XML specification then you know that as far as mark-up languages go, it is far more complicated than it needs to be. Writing an XML parser is supposed to be easy, but in practice is very hard to do correctly. This is a great example of how bad things get when technology is designed by committee.
Anyway, enough bitching. I currently need a simple and efficient markup language to represent textual data with a hierarchical structure, and I came up with the following format I'm calling PicoML:
document ::= "[#picoml]" tagged_content tagged_content ::= open_tag content close_tag content ::= text? (tagged_content | text)* open_tag ::= "[" text "]" close_tag ::= "[/]" text ::= ^("]" | "[" | "/" | "\") | escaped_char escaped_char ::= "\[" | "\/" | "\]" | "\\"And that is literally it! No attributes, no entities, no DTD's, no B.S. Just a compact, and easily parsed markup language.
It is trivial to map an XML document to PicoML. Take for instance the following XML:
<cd> <title>Maggie May</title> <artist>Rod Stewart</artist> <country>UK</country> <company>Pickwick</company> <price>8.50</price> <year>1990</year> </cd>This becomes in PicoML:
[cd] [title]Maggie May[/] [artist]Rod Stewart[/] [country]UK[/] [company]Pickwick[/] [price]8.50[/] [year]1990[/] [/]If someone goes around stuffing data in attributes (and violating the spirit of XML), the mapping is still trivial:
<stupid fu="bar"/>becomes the following:
[stupid][fu]bar[/][/]In fact I think there is a relatively trivial XSLT to do the mapping automatically. So who else is tired of looking at an emperor with no clothing?
