Problem with Parsing XML file with "."

3 New Member
Hi, I am using XML::Simple to parse the XML file that XML file contains the "." in some of its tags.

But while executing the script i am getting the error from Perl Script like "Use of uninitialized value in concatenation (.) or string".

I am aware of that this is because of the "." which is the concantation operator in Perl. But i want to parse the XML file without making nay chnages to it.

Hi as you informed i am posting the code here..

This is my Perl Code

use strict;
use XML::Simple;
use Data::Dumper;
my ($FILENAME, $Parser);
$FILENAME = "C:\\PerlScript \\Master.xml";
$Parser = XMLin($FILENAME );

print " $Parser->{properties}->{property}->{NCHOME.INSTAL LDIR}->{value}\n";

This is the XML File
<?xml version="1.0" ?>
- <CommonInstalle r version="1.0">
- <properties>
<property name="NCHOME.IN STALLDIR" value="[$NCHOME]" />
<property name="LICENSESE RVER.HOST" value="localhos t" />
<property name="LICENSESE RVER.PORT" value="27000" />
</CommonInstaller >

This is the Error i am getting while execute the Perl Scipt
Use of uninitialized value in concatenation (.) or string

The problem is the hash key:


because it contains a dot you have to quote it:


the error message has nothing to do with the dot in the hash key or the dots in the xml file. That is a generic error message you get when warnings are turned on and you try and print a variable that has not been initialized.

Hi, I am having problems with a function that I have been using in my program to read sentences from a 'command file' and parse them into commands. the surprising thing is that the program works fine on some computers and not so fine on others.

I narrowed it down to the seekg function and made this simple program which (from what I understand) does not seem to be working as expected in all...

Hello, I'm facing a big logical problem while writing a parser in VC++ using C. I have to parse a file in a chunk of bytes in a round robin fashion.
