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 theTiXmlDeclaration class. 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 inTiXmlUnknown so 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 aTiXmlComment object.
这是注释。生成TiXmlComment对象。
<ToDo>
The "ToDo" tag defines aTiXmlElement object. 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 anotherTiXmlElement which 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:
TiXmlDocument "demo.xml" TiXmlDeclaration "version='1.0'" "standalone=no" TiXmlComment " Our to do list data" TiXmlElement "ToDo" TiXmlElement "Item" Attribtutes: priority = 1 TiXmlText "Go to the " TiXmlElement "bold" TiXmlText "Toy store!" TiXmlElement "Item" Attributes: priority=2 TiXmlText "Do bills"原文链接:https://www.f2er.com/xml/299170.html
