Hi all,

I have a piece of HTML code containing two Perl variable names, which is to be used in 6 scripts. So I tried to put it into a separate file to be executed with "do page_head.pl", where page_head.pl contains something like (simplified):

my $page_head = qq{<?xml version="1.0" encoding="utf-8"?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="de" lang="de"><head><title>$title</title></head><body>UP<div class="textbox"><!-- begin content -->};

The obvious problem is, that the variables are not interpolated according to their current value in the scripts, i.e. although

$mother_id = 453;
and
$title = "Title";

The $page_head variable will an contain empty title tag and show_local.pl parameter after the do command.

How can I circumvent this without writing the html code in all the six scripts? eval does not seem to be an alternative here.

Thanks,

Jan
