Hi,
I'm working on a web templating system, and I'm wondering how should I use
rules?
I have these defs:
rule elem {
\< wts \: (<[a..z]>+) \/ \>
}
rule block {
\< wts \: (<[a..z]>+)\>(.*?)\< \/ wts \: $1 \>
}
I would like to execute subroutines during the evaluation. What should I
do? Is the following the right way?
given $template {
s/<block>/{trigger_block()}/;
s/<elem>/{trigger_elem()}/;
}
How can I catch the matched elem name, and block content? I'm guessing
that hypotetical variables can be the solution, but it says, that those
variables should have been defined, before I use them, and it's not that
case.
Bye,
Andras
