Use of uninitialized value $token

[Rainer Zufall]

Binary package hint: libxml-xpath-perl

I downloaded the HTML source of http://pgl.yoyo.org/as/iplist.php?ipformat=iptables, cleaned it up with tidy and then wanted to search for some xpath nodes.

The command line `xpath -e /html/ iptables.html` came with the following output:
Use of uninitialized value $token in concatenation (.) or string at /usr/share/perl5/XML/XPath/Parser.pm line 631.

Please make sure that $token has some value all the time and if it's not possible, do some fallback. Thanks,
