NAME

ETL::Pipeline::Input::Xml - Records from an XML file

SYNOPSIS

  use ETL::Pipeline;
  ETL::Pipeline->new( {
    input   => ['Xml', iname => 'Data.xml', root => '/Root'],
    mapping => {Name => 'Name', Address => 'Address'},
    output  => ['UnitTest']
  } )->process;

DESCRIPTION

ETL::Pipeline::Input::Xml defines an input source that reads multiple records from a single XML file. Individual records are repeating subnodes under "root".

METHODS & ATTRIBUTES

Arguments for "input" in ETL::Pipeline

records_at

Required. The path to the record nodes, such as /XMLDATA/Root/Record. The last item in the list is the name of the root for each individual record. The code loops over all of these nodes.

This can be any value accepted by Data::DPath. Fortunately, Data::Dpath takes paths that look like XPath for XML.

skipping

Not used. This attribute is ignored. XML files must follow specific formatting rules. Extra rows are parsed as data. There's nothing to skip.

Methods

run

This is the main loop. It opens the file, reads records, and closes it when done. This is the place to look if there are problems.

ETL::Pipeline automatically calls this method.
