Extract element name by XPath expression

[Daniel Frey]

Hello,

I'd like to extract the name of an indirectly addressed element by
subsequently using the childs position:

001 <a>
002 <b1/>
003 <b2/>
004 <b3/>
005 </a>

I.e. I tried for the first sub-element:

001 /a/*[1]/text()

but that does return some odd characters, mainly the linefeed and some
spaces. Do you know a way to do that?

Thanks
Daniel Frey

How are you evaluating your XPath expressions then?
I think /a/*[1] would give the <b1 /> element and as it is empty
/a/*[1]/text() should give an empty nodeset.

As for accessing the name of a node there are functions in XPath to do
that, local-name() for instance e.g.
local-name(/a/*[1])
see the XPath documentation here:
