Drupal 8/9 migration Traversing backward on an XML file

This is going to be a very short read. Although I was stuck scratching my head for hours trying to figure out how to traverse backwards of an XML file using XPath selectors.

It was supposed to be simple as using `../` syntax.

selector: '../../../../../@title

Well…., it won’t work if you have your data parse plugin set to XML.

So make sure it is set to simple_xml rather than XML, and you are good to go.

source:
  data_parser_plugin: simple_xml
