Re:  Sorting by child element count
Hi Michel,
Good idea if there is no better way. But since there are 400 <Item> elements in the list and hand counting is subject to error, I was hoping to automate the task. However, I can use this solution if no automated method is forthcoming.
Regards,
Mark

Maybe not the best way but you could copy/preprocess the Item elements
and add an atribute with the number of Data elements. Then sort on the
attribute.

Happy new year! Thanks for all the help this list has given me over the past
two years. My question:


I have an XML document that looks like the listing below. I want to sort the
<List> by <Item> so that all the <Items> with one <Data> element are
followed by all the <Items> with two <Data> elements, and so on, until the
last <Items> in the output list have the most <Data> elements. The <Data>
elements have to remain inside their original parent <Item>.


No clue how to begin. Can you point me in the right direction?

Thanks,
Mark

<List>
  <Item>
      <Data>...</Data>
          ... <!possibly 1 to 10 or so <Data> elements in each parent
<Item> element.
      <Data>...</Data>
  </Item>
   ... <!400 <Item> elements in the <List> >
</List>
