Re: Re: XML package for parsing values in the opening tag.

Thanks for the link to the specs.
I found another problem when a tag name contains an underscore.

<USER _City="testboro"></USER>
[download]

When I call the value...

print $xml->{USER}->{_CITY};
[download]

The following is printed out when calling the value...
"Use of uninitialized value"
Tempted to strip out the underscores but that would be poor coding standards plus an underscore could be used as an actual data value. I will go through the specs now.

Dump the data with Data::Dumper and see what the problem is, most likely you will need to do `print $xml->{'USER'}->{'_CITY'};` -Waswas	[reply] [d/l]

This is because XML::Simple by default cut the root node, since on XML we only have one root tag. Also you typed _CITY, upercase, that is different of _City, since XML is case sensitive. So, you actually should use: `print $xml->{_City} ;` [download] If you use XML::Smart it has an option to load a XML and parse all the nodes and attributes in upercase or lowercase: use XML::Smart ; my $xml = XML::Smart->new(q`<USER _City="testboro"></USER>` , uperta +g=>1 , uperarg=>1); print $xml->dump_tree_ok ; [download] Output: `$VAR1 = { 'USER' => { '_CITY' => 'testboro' } };` [download] Graciliano M.
