How to select all leaf nodes using XPath expression?

I believe it's possible but couldn't figure out the syntax. Something like this:

xmlNode.SelectNodes("//*[count(child::*) <= 1]")

but this is not correct.

Solution

  • Use:

    //node()[not(node())]

    In case only element leaf nodes are wanted (and this needs clarification -- are elements that have non-element children considered leaf nodes?), then the following XPath expression selects them:

    //*[not(*)]

    Both expressions above are probably the shortest that select the desired nodes (either any-node or element -- leaf nodes).
