Re: [xml] string-range in xpointers from python?

["Ross J. Reedstrom" <reedstrm rice edu>]

O.k, so this is better, some:
>>> print ctx.xpointerEval('xpointer(/cnx:document/cnx:content/cnx:para[1])')[0].content

      Geometric representation of signals can provide a compact
      characterization of signals and can simplify analysis of their
      performance as modulation signals.

>>> ctx.xpointerEval('xpointer(string-range(/cnx:document/cnx:content/cnx:para[1],"Geometric"))')
Unable to convert XPath object type 7

I see this same error from a list posting a year ago, May. I'm using
libxml2 2.6.26. Is there more complete support in CVS? Should I be
getting my devel setup functional, and see about providing a patch or
two?
