Flex的MXML文件结构
下面是一个MXML <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx=http://www.adobe.com/2006/mxml layout="absolute">
</mx:Application>
第一行声明XML文件采用的语法版本号和文件采用的编码格式。mx:Application标签是一个特殊的标签。在每一个MXML文件,但作为程序入口的运行文件只有一个,主文件的标示是根节点为mx:Application,一个程序中出现一个mx:Application节点。还有一个属性xmlns:mx=http://www.adobe.com/2006/mxml,表示将mx定义为XML的命名空间。xmlns标签专门用来定义XML的命名空间,XML命名空间可以用来定义一套独立的XML标签,并且为这些标签指定特殊的解析方式。比如XML文件中默认的标签格式为:<Button>node</Button>,这里的Button节点作为一个普通的文本节点,没有特殊的意义。定义命名空间后,在节点上加上空间前缀:<mx:Button></mx:Button>这时候就代表mx空间下的Button对象。 Mx命名空间对应的路径是”http:// www.adobe.com/2006/mxml”,Flex的配置文件中将这个路径定义为一个全局资源标识符,并对应了一个XML文件。在这个文件中,列出了mx命名空间下的所有标签。在Flex SDK
<namespaces> <namespace> <uri>http://www.adobe.com/2006/mxml</uri> <manifest>mxml-manifest.xml</manifest> </namespace> </namespaces>
从上面可以发现,” http://www.adobe.com/2006/mxml”这个URI和mxml-manifest.xml文件对应,打开该文件,该文件列出了MXML中的所有标签与标签关联的类文件路径。 <?xml version="1.0"?>
<componentPackage>
<component id="FileSystemComboBox" class="mx.controls.FileSystemComboBox"/> <component id="FileSystemDataGrid" class="mx.controls.FileSystemDataGrid"/> 。。。。。。。 <component id="WebService" class="mx.rpc.soap.mxml.WebService"/> <component id="WebServiceOperation" class="mx.rpc.soap.mxml.Operation"/>
</componentPackage>
在开发中,当程序有很多MXML文件和AS文件时,为了方便调用,我们可以将功能相似的文件放在一个文件夹中,定义一个命名空间在定义命名空间时,为了方便,很一般直接指定命名空间包括的标签路径。比如: xmlns:myComp=”components.*” 上面使用了通配符”*”, components目录下所有的MXML文件个ActionScript类文件都被包括在myComp命名空间下。例如components中有一个Loginpanel.mxml,则程序中调用这个文件时,代码如下 <myComp: Loginpanel></myComp: Loginpanel> myComp下的标签被自动指向components文件,当标签数量较多而且分布在不同文件夹时,可以效仿Flex配置文件的做法,使用XML文件来描述。 |
