Gurus,

This might be a merely question; but made me to be in perplexed state. The following regular expression I wrote is to validate a self closing tag in the XML. If there is more than one tag in the current line; I would handle in elsif (next line). 

#!/usr/bin/perl
$line = '<log dest="calllog"> directory <value expr="callRecDirPath"/>
+';
if ( $line =~ /<(\w(?:[^ \/>]+))(?:(?:(?:\s+)([^=>]+)\s*=\s*("|')([^\3
+]*)\3))\s*\/>/) {
        print ("1=" . $1. "\n2=" . $2 . "\n3=" . $3 . "\n4=" . $4 . "\
+n5=" . $5 . "\n");
}

But I got the flowing result:

1=log
2=dest
3="
4=calllog"> directory <value expr="callRecDirPath

[download]

From the above result; the value for 4 is the issue. The value for 3 is "; therefore ([^\3]*) should not have this double quote in its value. But the result 4 has two double quotes. How this happen? Can you please help me in this regard?

Thanks in advance.
