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?
