Hello dear Bioconductor users,

  Due to an update of XML package which was unfortunately not 100%
back-compatible (the xmlChildren() function returns list() instead of NULL
in case of child-less xml object), the KEGGgraph package of version 1.1.1 is
now not able to parse some KGML files. The issue has been solved in the
latest update (version 1.1.2). I am sorry for any inconvenience.

  If you still have problem to parse KGML files, please update XML package.
If the problem still insists, please do not hesistate to report.

  I thank Matt Settles and Yongjin Li very much for reporting the bug, and
especially Matt Settles for the fix.

  Best wishes,
Jitao David Zhang, Author and Maintainer of the KEGGgraph package
