[phpXML] Re: Searching on attributes

[<lu...@sa...>]

Tom

I read the FM several times ;-))
I tried
if ( !empty($month_name) )
             {
         $sorties = $xml->evaluate('//agenda/month[@name="$month_name"]');
             }
             else
             {
                $sorties = $xml->evaluate('//agenda/month');
             }
If I use this I get a

phpXML error: While parsing the XPath expression "$month_name" an empty and 
therefore invalid node-test has been found.

The FM doesn't say what does "an empty and therefore invalid node-test has 
been found" mean in plain english ;-))
