在asp下通过xml打包网站文件的方法

时间：2017-04-21 10:39

今天在网上找了下用xml打包文件、文件夹之类的内容看了看，在本机上调试了下，感觉还挺有用处

这个方法可以把整个文件夹打包到xml文件中，把这个xml文件文件和解包文件放在一起后，运行解包文件就可以把原来的文件释放出来，这样我们就可以把网站打包上传到虚拟主机，再运行解包文件就可以了。我在本地测试之选择了少部分文件，不知在文件很多的情况执行效率如何。
其实实现的思路也很简单，主要利用的是xml文件可以存放二进制数据的原理。有兴趣的朋友可以下载下面的附件研究下！！
解包文件

代码如下:

<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%> 
<% Option Explicit %> 
<% On Error Resume Next %> 
<% Response.Charset="UTF-8" %> 
<% Server.ScriptTimeout=99999999 %>

Set objXmlFile = Server.CreateObject("Microsoft.XMLDOM") 
    objXmlFile.load(Server.MapPath("update.xml")) 
    If objXmlFile.readyState=4 Then 
        If objXmlFile.parseError.errorCode = 0 Then 
            Set objNodeList = objXmlFile.documentElement.selectNodes("//folder/path") 
            Set objFSO = CreateObject("Scripting.FileSystemObject") 
                j=objNodeList.length-1 
                For i=0 To j 
                    If objFSO.FolderExists(strLocalPath & objNodeList(i).text)=False Then 
                        objFSO.CreateFolder(strLocalPath & objNodeList(i).text) 
                    End If 
                    Response.Write "创建目录" & objNodeList(i).text & "<br/>" 
                    Response.Flush

                            .Write objNodeList(i).nextSibling.nodeTypedvalue 
                            .SaveToFile strLocalPath & objNodeList(i).text,2
