看了一个CMS系统，当然大多都会有这样的功能。加入xml格式如下：

<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="iNethinkCMS">
  <sys_configuration>
    <WebName><![CDATA[iNethinkCMS]]></WebName>
    <InstallDir><![CDATA[/]]></InstallDir>
    <UrlMode>1</UrlMode>
    <TemplateCache>false</TemplateCache>
    <WebPageCache>false</WebPageCache>
    <CacheKey><![CDATA[CacheKey]]></CacheKey>
    <CacheTime>1200</CacheTime>
    <TemplateDir><![CDATA[/template/BasicDemo/]]></TemplateDir>
    <RewriteChannelPrefix><![CDATA[channel]]></RewriteChannelPrefix>
    <RewriteSpecialPrefix><![CDATA[special]]></RewriteSpecialPrefix>
    <RewriteContentPrefix><![CDATA[content]]></RewriteContentPrefix>
    <RewriteGuestbookPrefix><![CDATA[guestbook]]></RewriteGuestbookPrefix>
    <RemoteImgDown>true</RemoteImgDown>
    <UpFileType><![CDATA[zip,rar,txt,doc,docx,xls,xlsx,jpg,jpeg,gif,png,bmp,swf,wmv,avi,wma,mp3,mid]]></UpFileType>
    <UpFileMaxSize>1024</UpFileMaxSize>
    <PageListNum>10</PageListNum>
    <ImageSeconds>5</ImageSeconds>
  </sys_configuration>
</xs:schema>

不过真心觉得这样子很累，频发的操作，没有dtcms里面的反序列化思路好：

它的xml如下：
