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 @name=$argn]/> is made to look something like ... <xsl: variable name="pattern">@name=$arg1 or @name=$arg2 or @name=$argn</xsl:pattern> or <xsl: variable name="pattern">@name='$arg1 | $arg2 | $argn'</xsl:pattern> .... which would then be used as ... <xsl:template match='somecondition''> <xsl:apply-templates select=path/node[$pattern]/> </xsl:template> 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.
