There is a simple Perl script to do that:

my $Package = $ARGV[0];

open(INFO, "dpkg -L $Package |");

my (@Libs, @Headers) = ();

while(<INFO>)
{
    chomp($_);
    if(/\/lib(|64)\// and /\.so(\Z|\W)/) {
        push(@Libs, $_);
    }
    if(/\/include\// and $_ ne "/usr/include") {
        push(@Headers, $_);
    }
}

my $Version = `dpkg -s $Package|grep Version`;
chomp($Version);
$Version=~s/\AVersion:\s*//g;

print "
<version>
    $Version
</version>

<headers>
    ".join("\n    ", @Headers)."
</headers>

<libs>
    ".join("\n    ", @Libs)."
</libs>
";


Run this script as:

    perl script.pl package-dev

For example, it prints the following for libgrip-dev:

<version>
    0.3.5-0ubuntu1~12.04.1
</version>

<headers>
    /usr/include/libgrip
    /usr/include/libgrip/grip.h
    /usr/include/libgrip/gripinputdevice.h
    /usr/include/libgrip/gripgesturemanager.h
</headers>

<libs>
    /usr/lib/libgrip.so
</libs>
