xpath problem with xindice

[Chuck Amadi <ch...@breconbeacons.org>]

Hi there I'm having difficulty running xpath It seems that you need to 
have a node & attribute in oder to run the query Please advice if it's 
possible to use another notation as The xml documents I have residing in 
my NXD'S have very usefully query strings to find information as I 
intended from the start to have as less attributes as possible.
and use Elements <nodes)as often as possible .

Before you criticize someone,
you should walk a mile in their shoes.
That way, when you criticize them,
you're a mile away, and you have their shoes.

This is unlikely the cause of your problem, but since it is an outside 
possibility
I will mention it:

If you have a collection configured with
<collection compressed="false" name="xmlproject"> bla bla ...
and you have a value index on "section@label", the
results of your query qualified on section[@label="clear"] will be 
exactly as
you saw -- nothing selected. This is due to a bug in Xindice.

I say this is unlikely since most people probably have not
tried to use compressed="false".

Sorry for the confusing remarks by me xpath does work albiet it didn't 
do anthing when I tried _

}$ xindice xpath -c /db/xmlproject -q /article/section[@label="clear"] -v

only worked when I tried this }$ xindice xpath -c /db/xmlproject -q 
 /article /section -v
thus the node and attribute have been omitted. I will take a look at a 
tutorial but I'm fairly comfortable with xpath .

Please be more specific about your problem.  There need be no attributes in
either the document or the query in order to use XPath.  XPath also allows
various functions to be applied to the text of an element.  Perhaps a look
at the XPath spec or some XPath tutorial would be helpful.
