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.
