有能实现标签化的模板引擎吗？
0
[待解决问题]
像动易的标签，比如{PE.DataSource id="cone" datasource="图片栏目循环列表信息" /}
有朋友向我推荐了razor和Nvelocity，可是似乎这些模板引擎在前台还要出现if else等等的控制语句，不能简单到仅仅一个标签的程度
请问大家，有没有像动易那样，把所有前台除了最基本的html标签之外的内容都表示成一个标签的方法？不要任何的控制语句出现，全部标签也只是{PE.DataSource id="cone" datasource="图片栏目循环列表信息" /}这种形式，不要搞成多行那么麻烦
只有这样，前台的人员才可以真正做到不需要后台的任何技术要求
有没有这样的模板引擎呢？
另外还有一个问题是：在mvc和webform两种架构方式上都能使用模板引擎吗？有什么区别吗？

哈哈哈哈，我写了一个
方式一：
<!--li:SoftDown_SoftInfo|10|SoftName,jianjie,SN,path,domain,prefix,Replace(Round(score/scoreNum,1),'00000000000','') as score,images|CatalogID={$CatalogID$} or CatalogID in(Select CatalogID from [SoftDown_Catalog] where ParentID={$CatalogID$})|
1:
<dt>
<a href="{domain}{path}{prefix}{SN}.html" class="img">
<img src="{images}" />
</a>
<div class="inf">
<a class="title" href="{domain}{path}{prefix}{SN}.html">{SoftName}</a>
<p>{jianjie}<a href="{domain}{path}{prefix}{SN}.html">[详情]</a></p>
<span>评分：<em>{score}</em></span>
</div>
</dt>
@
9:
<dd>
<span>{score}</span>
<em>[i].</em><a href="{domain}{path}{prefix}{SN}.html">{SoftName:16}</a>
<p>{jianjie:20}</p>
</dd>
|no Resault
|MonthHits desc-->

提供 [i] 变量 用于 输出 1，2，3，4，5，6
提供变量[D:y-m-d,日期字段名] 用于 输出格式化的日期

nvelocity 你可以基于其再封装自己的标签
