XPath and attributes
(Using dbXML beta 4, Java 1.4 rc, WinXP)
I'm trying to reference the 'src:key' attribute of the following
document using XPath....
<?xml version="1.0" ?>
<node xmlns:src="http://www.dbxml.org/Query" src:col="/db/root/ocs"
src:key="37005840459e2954000000ec5d2a0272">
</node>
The XPath query i've been trying is...
/node[@src:key = '37005840459e2954000000ec5d2a0272']
and dbXML generates lots of 'debug' exceptions... not very helpful!
DEBUG> javax.xml.transform.TransformerException: Expected ],
but found: '37005840459e2954000000ec5d2a0272'
DEBUG> javax.xml.transform.TransformerException: Extra illegal
tokens: ''37005840459e2954000000ec5d2a0272'', ']'
If I omit the namespace bit 'src:', then no exceptions, but no
documents returned.
Can anyone help?
Regards,
Richard.
Re: XPath and attributes
Posted by Kimbro Staken <ks...@xmldatabases.org>.
You can't, the src:key attribute is added to the result after the query is
executed. We're looking at extending the ability to query across metadata
like this. it might be a couple releases before it shows up though.

Matthew,
There is an xmldb-xupdate.jar, maybe you are picking up an old one?
Did you try removing the "<?xml version="1.0">"?

Re: XUpdate
Posted by Matthew Egbert <ma...@epcc.ed.ac.uk>.
Thanks for the speedy reply Mark,
Unfortunately, it doesn't seem to be the collection that's causing the
problem...
xindiceadmin lc -c /db
locates the collection no prob, and I'm capable of performing:
- XPath queries to the collection
- document submission to the collection
(both via a java application which closely resembles the example apps,
and both without a hitch)
As I've worked with Xindice, axis and tomcat, I have had a few problems
which have been related to the java classpath. But this doesn't seem to
be that kind of error...am I wrong? Which packages are to be included in
the classpath to use xupdate (aside from the obvious xmldb.jar)?
Thanks again for the help.
Cheers,
Matthew

I love responding to my own e-mail ;-).
Also, try:
xindiceadmin lc -c /db
This will list out your collections. Looking at the error, it seems to be dying when
it trys to query the collection.

Re: XUpdate
Posted by "Mark J. Stang" <ma...@earthlink.net>.
I have been doing a lot with XUpdate. It seems to be working fine. I thought
there was a bug, but it ended up being my XML.
I compared your code with mine, the only difference that I saw was that your
XUpdate XML has "<?xml version="1.0">. I only pass in the <xupdate:modifications...>
for the update. I don't know if that is enough to cause it to die. Also, anytime
my "xupdate" fails, it does so by not doing the update. Does the collection exist?
Try using the collection for something more mundane.
HTH,
Mark
The xupdate xml is:
----------------------------------------------------------
<?xml version="1.0"?>
<xupdate:modifications version="1.0"
xmlns:xupdate="http://www.xmldb.org/xupdate">
<xupdate:insert-before select="/posting/to">
<xupdate:comment>updated</xupdate:comment>
</xupdate:insert-before>
</xupdate:modifications>

XUpdate
Posted by Matthew Egbert <ma...@epcc.ed.ac.uk>.
Hello,
I am learning how to use XUpdate with Xindice...Regardless of the
XUpdate xml, I get the following exception:
org.apache.xindice.client.corba.db.APIException: IDL:org/apache/xindice/client/corba/db/APIException:1.0

org.apache.xindice.client.corba.db.APIExceptionHelper.read(Unknown Source)

at
org.apache.xindice.client.xmldb.services.XUpdateQueryServiceImpl.update(Unknown
Source)
at XUpdateTest.main(XUpdateTest.java:37)
XML:DB Exception occured 1 Query Processing Error
The java source is:
----------------------------------------------------------
import org.xmldb.api.base.*;
import org.xmldb.api.modules.*;
import org.xmldb.api.*;
import java.io.FileReader;
import java.io.BufferedReader;
/**

*/
public class XUpdateTest {
public static void main(String[] args) throws Exception {
Collection col = null;
try {
String driver = "org.apache.xindice.client.xmldb.DatabaseImpl";
Class c = Class.forName(driver);
Database database = (Database) c.newInstance();
DatabaseManager.registerDatabase(database);
col =
DatabaseManager.getCollection("xmldb:xindice:///db/bbs");
BufferedReader file_reader = new BufferedReader (new
FileReader(args[0]));
String temp;
String xupdate=new String();
temp = file_reader.readLine();
while (temp != null) {
xupdate=xupdate+temp;
temp=file_reader.readLine();
}
System.out.println("\nXUpdate
Command:\n--------------------------\n"+xupdate+"\n\n\n\n");
XUpdateQueryService service =
(XUpdateQueryService) col.getService("XUpdateQueryService",
"1.0");
service.update(xupdate);
}
catch (XMLDBException e) {
System.err.println("XML:DB Exception occured " + e.errorCode +
" " +
e.getMessage());
}
finally {
if (col != null) {
col.close();
}
}
}
}
The xupdate xml is:
----------------------------------------------------------
<?xml version="1.0"?>
<xupdate:modifications version="1.0"
xmlns:xupdate="http://www.xmldb.org/xupdate">
<xupdate:insert-before select="/posting/to">
<xupdate:comment>updated</xupdate:comment>
</xupdate:insert-before>
</xupdate:modifications>
The output is:
----------------------------------------------------------
$ java XUpdateTest eg_xupdate.xml
XUpdate Command:
--------------------------
<?xml version="1.0"?><xupdate:modifications
version="1.0" xmlns:xupdate="http://www.xmldb.org/xupdate">

Does anyone have any suggestions as to where to start looking for the
problem? Is this a xindice bug/is XUpdate still in beta?
Cheers,

Re: XPath and attributes
Posted by Richard Hosking <ho...@yahoo.co.uk>.
Yes, I know how to do it from code... I need to use
XPath though, because the query string is read from a
script file.
Regards,
Richard.

Why don't you use: Collection.getResource( your_wanted_id );
Instead?

Betreff: XPath and attributes
(Using dbXML beta 4, Java 1.4 rc, WinXP)
I'm trying to reference the 'src:key' attribute of the following
document using XPath....
<?xml version="1.0" ?>
<node xmlns:src="http://www.dbxml.org/Query" src:col="/db/root/ocs"
src:key="37005840459e2954000000ec5d2a0272">
</node>
The XPath query i've been trying is...
/node[@src:key = '37005840459e2954000000ec5d2a0272']
and dbXML generates lots of 'debug' exceptions... not very helpful!
DEBUG> javax.xml.transform.TransformerException: Expected ],
but found: '37005840459e2954000000ec5d2a0272'
DEBUG> javax.xml.transform.TransformerException: Extra illegal
tokens: ''37005840459e2954000000ec5d2a0272'', ']'
If I omit the namespace bit 'src:', then no exceptions, but no
documents returned.
Can anyone help?
Regards,
Richard.
