Title: Can Xpath 1.0 print "position()" results? The following XPath 1.0 expression returns the value of
position():
position()
It doesn't print it of course, XPath doesn't know anything
about printers, that part is up to you.
But this isn't very useful. The value of position() is the
"context position" in the dynamic evaluation context of the XPath expression,
which is whatever the caller sets it up to be. In fact, most XPath APIs don't
give you any way to initialize the context position to anything but 1, and I'm
not sure what use it would be if they allowed anything else. (An exception is
when XPath is embedded in XSLT, in which case the context position tells you
something about what's happening on the XSLT side of the
boundary.)
I suspect you don't want to know the context position at
all. I suspect you want to know the position of some node in a tree relative to
its neighbours, for example the number of preceding siblings it has. If you
explain what you really want, then I'm sure we can tell you how to get
it.
