Because your Markup-Data function steps Xml-Tags through its series
value (initialized to a 5-element block) and then leaves it positioned
at the end. Therefore, on the next call, the Length? is zero.
Either use a local (to the function) variable, initialized as in
working-xml-tags: copy xml-tags
and iterate over the copy, or add
xml-tags: head xml-tags
at the end of Markup-Data.

Your function Markup-Data essentially steps Xml-Tags through its
series value, leaving it positioned at the end of the series.
