Hi All,
I'm using XML::Simple to parse a very simple XML file and dump the data
into hashes of hashes.
The problem I'm getting, is sometimes information is blank in the XMl
file; it looks like this:
<STREETNUM/>
instead of
<STREETNUM>1234</STREETNUM>
and when I print the hash:
print "$x->{VEHICLE}->{STREETNUM} ";
it returns: "HASH(blahblah)";
How do I test for this so it prints blank? I've tried many things, the
most logical I could think of was:
if ($x->{VEHICLE}->{STREETNUM}){ print ... }
else { print ""; }
Two ways to do this:
1) use SuppressEmpty option. This will simply exclude the STREETNUM
element if it is empty (no attributes and no content)
2) use ForceContent option. This will treat the STREETNUM element as a
hash even if it is empty or contains only text. In this case you would
use $x->{VEHICLE}{STREETNUM}{content} in your code.
#2 would probably be safer, because it would handle attributes to
STREETNUM elements properly.
You can read more about these options in the XML::Simple documentation.
