in reply to Issue with looping through XML::LibXML::Reader

The problem seems to be that you are reading the next Instrmt element in a while loop and as a result you skip the parent MktDataFull elements.

If you change the while() to an if() it should fix the main issue.

... if ( $reader->nextElement( 'Instrmt' ) ) { my $Sym = $reader->getAttribute( 'Sym' ); ...

    As easy as that..... Thank you so much for the quick and helpful response John.

    I did have also comment out one of the last read requests ($reader->nextSibling() > 0 or last;) as well, and it now works as it should.

[erix]: the annoying thing is that during setup of the 'foreign table' you have to specify all the columns. But that is reasonably automatable (just reading header line, and contruct the needed CREATE FOREIGN TABLE' statement)
[erix]: it may be easier to just slurp your fils into regular tables. Has other infrastructure advantages also (indexes, constraints etc)
