tinyxml：快速入门----一个官方带说明示例的翻译

How TinyXML works.
TinyXML如何工作的

An example is probably the best way to go. Take:

例子是最好的入门办法。例如：

<?xml version="1.0" standalone=no><!-- Our to do list data --><ToDo><Item priority="1"> Go to the <bold>Toy store!</bold></Item><Item priority="2"> Do bills</Item></ToDo>

Its not much of a To Do list, but it will do. To read this file (say "demo.xml") you would create a document, and parse it in:

这并不是一个很好的To Do清单，但用来示例足够了。读取这个文件（且称为"demo.xml"），你需要创建一个document，然后用它来解析：

TiXmlDocument doc( "demo.xml" );doc.LoadFile();

And its ready to go. Now lets look at some lines and how they relate to the DOM.

这样就准备好了。现在来看看一些代码，看他们如何跟DOM联系起来。

<?xml version="1.0" standalone=no>

The first line is a declaration, and gets turned into theTiXmlDeclarationclass. It will be the first child of the document node.

第一行是一个声明，生成TiXmlDeclaration对象。这是document的第一个孩子。
This is the only directive/special tag parsed by TinyXML. Generally directive tags are stored inTiXmlUnknownso the commands wont be lost when it is saved back to disk.

这是TinyXML解析的唯一一个directive tag。其他的directive tag存储在TiXmlUnknown，所以当他们存储到磁盘时，不会丢失。

<!-- Our to do list data -->

A comment. Will become aTiXmlCommentobject.

这是注释。生成TiXmlComment对象。

<ToDo>

The "ToDo" tag defines aTiXmlElementobject. This one does not have any attributes, but does contain 2 other elements.

To Do tag生成TiXmlElement对象。这个tag没有包含任何属性（attribute），但它包括两个元素（element）

<Item priority="1"> 

Creates anotherTiXmlElementwhich is a child of the "ToDo" element. This element has 1 attribute, with the name "priority" and the value "1".

这是TiXmlElement元素，也是To Do元素的一个孩子。这个元素有一个属性，name是"priority"，值是"1"。

Go to the

A TiXmlText. This is a leaf node and cannot contain other nodes. It is a child of the "Item"TiXmlElement.

这是TiXmlText对象，这是一个叶节点，不包括其他子节点。这是"Item"的孩子。

<bold>

Another TiXmlElement, this one a child of the "Item" element.
另一个TiXmlElement元素，是"item"的子节点

Etc.
等等。

Looking at the entire object tree, you end up with:

看看完整的对象树，你将得到：
