通过ASP或XSL过滤XML?

我了解我的基础知识，完全无法实现.

我有一个projects.xml文件，其中包含我所有客户项目的列表.
默认情况下，我的网页应显示所有项目，或按项目名称或客户过滤项目.

我想知道应用过滤器时的最佳做法:
-对每个过滤器应用不同的xsl
-使用asp访问xml并过滤信息，然后再将其发送到xsl

如果我需要为客户A选择所有项目，我应该使用XL函数(for-each)还是ASP使用DOM函数?

xml的示例:

Hi,

I know my basics and I have difficulties implementing it altogether.

I have a projects.xml file containing the list of all my customers projects.
My web page should by default show all projects, or filter projects by project Name or Customer.

I want to know what is best practice when applying my filters:
- apply a different xsl to each filter
- use asp to access xml and filter the info before it is sent to xsl

if I need to select all the projects for Customer A, would I use xls (for-each) or ASP using DOM functions?

Example of the xml:

<projects>
   <project>
       <projname>Project A1</projname>
       <customer>A</customer>
   </project>
   <project>
       <projname>Project A2</projname>
       <customer>A</customer>
   </project>
   <project>
       <projname>Project B</projname>
       <customer>B</customer>
   </project>
</projects>
