in reply to Filtering large XML files

To "extract" a node in XML::LibXML::Reader, use copyCurrentNode: 
    if ('text' eq $r->name and XML_READER_ELEMENT == $r->nodeType) {
        print $r->copyCurrentNode(1);
    }

    Thanks, this might work. Do you have any idea how to go about the <doc> node? I cannot simply use copyCurrentNode on that one. When I do this:

    if ('doc' eq $r->name and XML_READER_ELEMENT == $r->nodeType) {
        print $r->copyCurrentNode(0)->toString;
    }

    I get:

    <doc attr1=".." attr2=".."/>

    (an empty, self-closed <doc/>). Is there a clean way to correctly output it as just an opening XML_READER_ELEMENT?
