XPath Query, HELP

18 May 2004 23:24:45 -0000

Hi

 

I am a newbie to both xindice and xpath.

 

I have added following document to collection /db/description and tried to test xpath with following queries

 - xindice xpath –c /db/description –q /Mpeg7

 - xindice xpath –c /db/description –q /Mpeg7/Description

 - xindice xpath –c /db/description –q //Label

- xindice xpath –c /db/description –q /*/*

 

 

However only the last query returns result and the other return nothing.

Can someone help me fix my xml doc or my xpath query please ?
