in reply to XML::LibXML - could not create file parser context : no error

It's only a guess but since you mention "iteration" and don't show any, there's a reasonable chance that the problem is related to how you are performing this "iteration". If you can post a complete, small self-contained script, together with sample input data which demonstrates the problem it might then be possible to see precisely where the problem lies.

    Hi Hippo, You can assume it to a function happening at regular intervals like the below : 
    sub parsexml {

my $parser_obj = XML::LibXML->new();
my $doc;
my $xml_file = "filename.xml";
$doc = $parser_obj->parse_file($xml_file);
my ($xml_node) = $doc->findnodes($xpath);
}

parsexml();
sleep 30;
parsexml();
sleep 30;
.
.

    The overall thing happening is , same file is accessed multiple times or parsed multiple times this way over a period of time. I am not sure, if the problems lies here or not. Please revert if more details are required. Thanks, Bala.

      Problem is somewhere else, I would say, as the following works for me without problem: 
      for (1 .. 10000) {
    my $p = 'XML::LibXML'->new;
    my $d = $p->parse_file('example.xml');
    my $n = $d->findnodes('/');
}

      Does any other process overwrite the file at the same time?

        Hi Choroba, The file is actually only read and nothing is written to it. Also, the file is not accessed by any other processes. Does the error statement "No error" has any significance ?? Thanks, Bala.
