Re^3: XPath query issue...

The issue is just that - the @ is being interpreted as a global symbol and it should behave as a XPATH symbol signifying the attribute.


my $query = "/nvd/entry[@id = $cve_id]";

my $xp = XML::XPath-> new(filename => "$data_file");

foreach my $cve_entry ($xp->findnodes($query)) {
}

You need to escape the @ somehow so perl does not try to interpolate it: `my $query = '/nvd/entry[@id = ' . $cve_id . ']';` [download] or `my $query = "/nvd/entry[\@id = $cve_id]";` [download] -derby	[reply] [d/l] [select]
