xsl apply templates select
I have some challenges to solve:

I need to parse a string that contains n number of args, which is in the 
form of  "arg1, arg2,...argn". The args define either an attribute or 
element value. The goal is to prune a large tree using the given arguments.

I want to dynamically create a pattern for the following using the above 
input string, such that

    <xsl:apply-template select=path/node[@name=$arg1 or @name=$arg2 or 

is made to look something like

    <xsl: variable name="pattern">@name=$arg1 or @name=$arg2 or 
    <xsl: variable name="pattern">@name='$arg1 | $arg2 | 

which would then be used as
    <xsl:template match='somecondition''>
        <xsl:apply-templates select=path/node[$pattern]/>

The questions are:
Can the select attribute accept pattern defined by a variable? So far I 
haven't been able to make it work.
If yes, how should it be constructed based on the given input string?
If no, what would be an approach to filter a tree based on the given input?
Or even if yes, is there a better way to filter a large tree?

Thanks in advance.
