parentheses (")", called a tree, which can contain Subtrees. The ebnf definition of sgf is as follows (see http://www.red-bean.com/sgf/sgf4.html#ebnf-def ):
Collection = gametree {gametree}
The following is a simple and representative sgf text. Let's have a perceptual knowledge:
(; FF [4] GM [1] SZ [19] FG [257: figure 1] PM [1]
Programmers who are familiar with writing text parsers should be clear about it. According to the definition of ebnf, it is quite simple and intuitive to write th

Introduction
The compiler preprocessing, lexical analysis and lexical analyzer are introduced, and the task and process of parsing are also mentioned.
The input of parsing is the sequence of lexical elements, then according to the grammatical representation (expansion) of the language, using the finite state machine theory, the abstract syntax tree is generated, and then the intermediate code, that is, the three address code is traversed. This section, in an experimental way, looks at the intrin

, this is basically equivalent to a large job in the Compilation Principle Course.In other words, the syntax is only for display. The reason why the script appears is to lower the programming threshold. If the syntax of a language is like lisp, it is directly the pattern of the abstract syntax tree, which saves the parsing step. It saves a lot of trouble to execute it. However, it is clear that a program like this abstract syntax tree style is not enjoyed and can be easily accepted by everyone.I
, but it is very important for the software that needs to process this element:
XML Element vs. Attributes
See these examples:
In the first example, sex is an attribute. In the second example, sex is a child element. Both examples provide the same information.
There are no rules to tell us when to use attributes and when to use subelements. In my experience, attributes are easy to use in HTML, but in XML, you should try to avoid using attributes. If the information is similar to data, use
