XML是一种标记语言，被设计用来存储数据和传输数据。
|
||||
|
||||
不像HTML, XML不指定怎样显示或格式化数据，只是携带它。
|
||||
|
||||
|
||||
* XML 语法
|
||||
|
||||
```xml
|
||||
<!-- XML中的注解像这样 -->
|
||||
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
<bookstore>
|

<!-- 上面是一个典型的XML文件。
|
||||
它以一个声明开始，通知一些元数据（自选的）
|
||||
|
||||
XML使用一个树的结构。上面的文件中，根节点是'bookstore'，它有三个孩子节点，
|
||||
所有的'books'。那些节点有更多的孩子节点，等等。。。
|
||||
|
||||
节点用开放/关闭标签创建， 并且孩子就是在开发和关闭标签之间的节点。-->
|
||||
|
||||
|
||||
|
||||
<!-- XML 携带两类信息:
|
||||
1 - 属性 -> 那是关于一个元素的元数据。
|
||||
通常，XML解析器使用这些信息去正确地存储数据。
|
||||
它通过在开放标签里出现在插入语中来表示。
|
||||
2 - 元素 -> 那是纯数据。
|
||||
那就是解析器将从XML文件提取的东西。
|
||||
元素出现在开放和关闭标签之间，没插入语。-->
|
||||
|
||||
|
||||
<!-- 下面, 一个有两个属性的元素-->
|
||||
<file type="gif" id="4293">computer.gif</file>
|
||||
|
||||
|
||||
```
|
||||
|
||||
* 良好格式的文件 x 验证
|
||||
|
||||
一个XML文件是良好格式的如果它是语法正确的。
|
||||
但是， 使用文件定义，比如DTD和XML概要，在文件中插入更多的限制是可能的。
|
||||
|
||||
一个遵守一个文件定义的XML文件被叫做有效的，对于那个文件来说。
|
||||
|
||||
有了这个工具，你能够在应用逻辑之外检查XML数据。
|
||||
|
||||
```xml
|
||||
|
||||
<!-- 下面, 你能够看到一个简化版本的增加了DTD定义的bookstore文件。-->
|
||||
|

|
||||
<price>30.00</price>
|
||||
</book>
|
||||
</bookstore>
|
||||
|
||||
<!-- 这个DTD可能是像这样的:-->
|
||||
|

<!ELEMENT bookstore (book+)>

|
||||
]>

||||
|
||||
|
||||
<!-- 这个DTD以一个声明开始。
|
||||
接下来, 根节点被声明， 它需要一个或多个孩子节点'book'。
|
||||
每个 'book' 应该准确包含一个 'title' 和 'price' 和
|
||||
一个被叫做'category'的缺省值为"Literature"的属性。
|
||||
