Question

This is the current state:

HTML FILE:
<!--#set var="header-title" value="Help - Frequently Asked Questions - FAQ" -->
<!--#set var="header-description" value="Answers to common questions about ..." -->
<!--#include virtual="includes/header-basic.htm" -->

INCLUDE FILE:
<!--#if expr="" -->
  Variables:
    header-title
    header-description
<!--#endif -->
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en" />
<head>
...

RENDERED HTML:



<!DOCTYPE... (output starts here after several blank lines)

But I would like to squeeze the whitespace out of the rendered HTML. Is this possible? Also, I used hexdump to confirm I do not have UTF8 BOM in my file.

Was it helpful?

Solution

Thanks to (Ivan Shmakov) comp.infosystems.www.servers.unix. One approach is:

<!--#set var="header-title" value="Help - Frequently Asked Questions - FAQ" 
--><!--#set var="header-description" value="Answers to common questions about ..." 
--><!--#include virtual="includes/header-basic.htm" -->

Also, another option (undocumented Apache behavior?) is to combine set directives:

<!--#set 
  var="header-title" value="Help - Frequently Asked Questions - FAQ"
  var="header-description" value="Answers to common questions about..."
--><!--#include virtual="includes/header-basic.htm" -->
