Description Heiko Jansen 2013-09-04 15:07:04 UTC 
LibXSLT behaves unexpectedly and imho inconsistently when I try to use "position()" to match certain elements.

When I try to transform the simple xml tree in the attached "input.xml", the stylesheets "ok1.xslt" and "ok2.xslt" give this output:
<OUT_TREE>
  <OUT_TWIG>
    <OUT_LEAF_FIRST>a_first</OUT_LEAF_FIRST>
  </OUT_TWIG>
  <OUT_TWIG>
    <OUT_LEAF_FIRST>b_first</OUT_LEAF_FIRST>   <!--- cf. below
    <OUT_LEAF_OTHER>b_second</OUT_LEAF_OTHER>
  </OUT_TWIG>
</OUT_TREE>

Using "dubious.xslt", however, leads to this result:
<OUT_TREE>
  <OUT_TWIG>
    <OUT_LEAF_FIRST>a_first</OUT_LEAF_FIRST>
  </OUT_TWIG>
  <OUT_TWIG>
    <OUT_LEAF_OTHER>b_first</OUT_LEAF_OTHER>    <--- here
    <OUT_LEAF_OTHER>b_second</OUT_LEAF_OTHER>
  </OUT_TWIG>
</OUT_TREE>

To verify the inconsistency I ran the same tests using Xalan-C (Xalan version 1.11.0, Xerces version 3.1.1), Xalan-J2 (2.7.0), and Saxon9 (Saxon-HE 9.4.0.4J ) on openSUSE 12.3 x64. All three processors give me the first output shown above with any of the three stylesheets.

So only xsltproc behaves differently when using "dubious.xslt".
