Inter-document Queries
Hi everybody,
Does anyone know if there is a way to perform some
inter-document queries in Xindice ? I mean can we for example perform
some kind of a join between two documents in Xindice ?
For example I want to be able to write a query that returns the result
of a join between the two or three documents in database. Is this possible ?
e.g.
document('p.xml')/stores/store[@id=$delta/@id] where $delta =
document('s.xml')/products/product/store
Is there any way to do it ?
I'd appriciate any help.
Regards,
George

Thanx !
I was afraid of it. Unfortunately this means that I have to create a
query processor with my own that undertakes to perform all these ... :-(
...
Wish me good luck !!!
Regards,
George

The NoClassDefFoundError appears because you didn't have ANT installed.
(or didn't set ANT_HOME). ANT is needed to build Xindice yourself.

Yet anoter one who can't get Xindice to run
Posted by Eskil Saatvedt <es...@ii.uib.no>.
I am trying to get Xindice to run on my home computer and get an error,
I found others on the mailing list to have had simmelar problems but
could not get it working by the answers there. What do I do wrong?
Error:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/tools/ant/Main
I am running on Win 98, Java version 1.4.1_01, xindice is unnpacked under
D:\xindice
The error occur when I run: build
If I run: startup ,i get a loong list of errors ending with:
Exception in thread "main" java-lang.OutOfMemoryError
Here is a part of my Autoexec.bat file
PATH C:\WINDOWS;C:\WINDOWS\COMMAND;D:\j2sdk1.4.1_01\bin;D:\xindice\bin
SET JAVA_HOME=D:\j2sdk1.4.1_01
SET XINDICE_HOME=D:\xindice
SET CLASSPATH=D:\j2sdk1.4.1_01;.;D:\desktop\java;D:\xindice\java\lib\xindice.jar;D:\xindice\java\lib\xmldb.jar;D:\xindice\java\openorb-1.2.0.jar;D:\xindice\java\lib\xerces-1.4.3.jar;D:\xindice\java\lib\xalan-2.0.1.jar
I hope someone can assist me and guide me in the right direction.

George,
Not really. Your best option is to use XPath and specify multiple
conditions with "ands and ors". Event then, it will only let you
"select" multiple documents, it won't allow you to combine
pieces of each.
HTH,
Mark
