Retains all elements with a given name to support extraction from parents.

This is a hack to support field extraction of values in parents of the 'context node' - ie, if $this->fields() has something like '..\nid'. Since we are using a streaming xml processor, it is too late to snoop around parent elements again once we've located an element of interest. So, grab elements with matching names and their depths, and refer back to it when building the source row.
