InfoPath 系列：了解INFOPATH XSN文件的格式（1）
这一章我来为大家介绍一下INFOPATH的文件格式。前面几篇中我们用到例子在发布之后无论是客户端版本的还是WEB版本的都会生成一个xsn文件。这个文件扩展名是INFOPATH文件的扩展名，但我们用其它软件一样可以打开它，下面我们就来看看这里面到底有什么。
这里声明的文件在上面的列表中都可以看到,这一部分就是用来声明这个xsn文件的组成部分的。接下来是一些扩展信息，例如改xsn的视图信息、发布信息、缓存信息、xsn文件信息等。代码如下：
首先，我们找到之前生成的XSN文件，将它的扩展名改为.zip。然后用任何一种解压工具将其解压，解压后所得到的文件如下图所示：
下面就一个一个来看，
manifest.xsf：顾名思义，就是一个清单，先看看里面都有什么东西吧，打开这个文件后除了头部的各种声明信息外接下来就是包内的文件信息：

接下来的是上面定义的视图信息的具体描述，这里定义了绑定和未绑定的控件，也将mainpane指向了xsl文件，通过xsl文件可以将界面呈现出来。

unboundControls定义了没有进行数据绑定的控件，也就是表单中的提交按钮。
接下来的两项是关于schema和命名空间的设置：

<
xsf:applicationParameters
application
=
"InfoPath Design Mode"
>
<
xsf:solutionProperties
lastOpenView
=
"view1.xsl"
fullyEditableNamespace
=
"http://schemas.microsoft.com/office/infopath/2003/myXSD/2010-05-17T14:43:28"
></
xsf:solutionProperties
>
</
xsf:applicationParameters
>
<
xsf:documentSchemas
>
<
xsf:documentSchema
rootSchema
=
"yes"
location
=
"http://schemas.microsoft.com/office/infopath/2003/myXSD/2010-05-17T14:43:28 myschema.xsd"
></
xsf:documentSchema
>
</
xsf:documentSchemas
>
|
然后是对于初始化数据的设置，也就是新打开一个表单的时候数据源的数据是什么状态，从下面的设置可以看出，初始化数据是指向了template.xml文件。

<
xsf:fileNew
>
<
xsf:initialXmlDocument
caption
=
"请假申请表Publish"
href
=
"template.xml"
></
xsf:initialXmlDocument
>
</
xsf:fileNew
>
|
最后是关于提交选项的定义，不知道大家是否还记得之前表单中关于提交的设置项，可以参照前一篇博文来查看提交项的定义。

>
<
xsf:successMessage
>请假申请已提交，请等待审批。</
xsf:successMessage

<
xsf:errorMessage
>由于出现错误，无法提交表单。</
xsf:errorMessage
>
<
xsf:davAdapter
name
=

submitAllowed
=
"yes"
overwriteAllowed
=
"no"
>
<
xsf:folderURL
value
=
"http://172.17.9.168/Shared%20Documents/"
></
xsf:folderURL
>
<
xsf:fileName
value
=
"concat(my:Department, "-", my:FullName, "的请假申请单")"
valueType
=

></
xsf:fileName

</
xsf:davAdapter

</
xsf:submit

通过上面的了解我们发现，XSN文件实际是一个ZIP包，表单中使用的元素及表单设置都被压缩到了这个包里，而manifest是这些资源的目录，也是表单的配置文件。下一篇我会为大家讲解另外几个文件的作用。感谢大家的支持，请大家继续关注我的博客，谢谢。
