Description

Given the following XML:

<root>
  <Level1>
    <Level2preceding>Included</Level2preceding>
    <Level2>
      <data>Hello, World!</data>
      <data>Hello, Camel!</data>
      <data>Hello, Apache Foundation!</data>
    </Level2>
    <Level2following>Not Included</Level2following>
  </Level1>
</root>

and the following xtokenizer:

<xtokenize mode="w">/root/Leve1/Level2/data</xtokenize>

will yield the following result:

<root>
  <Level1>
    <Level2preceding>Included</Level2preceding>
    <Level2>
      <data>Hello, World!</data>
    </Level2>
  </Level1>
</root>

Please note that the node <Level2following/> is missing while <Level2preceding/> is included. Since both nodes are a child of <Level1/> the tokenizer should include <Level2following/>, too, since they are a child of a ancestor of the <data/> node which the splitter processes.

The documentation mentions that the mode "w" will include the node in its ancestor content. Strictly speaking, the XPath ancestor would exclude <Level2preceding>. If I understand the XPath spec correctly the current implementation uses ancestor:: | preceding:: as the wrapper which it is a bit counterintuitive.
