Re: [xmlblaster] Does XPATH filter apply to ClientTags?

I'm trying to filter using Xpath. 

FYI - I've set "-agent" on the command line to 1000 and I get it in the code
via:
String agent = glob.getProperty().get("agent", "0001");

I've set the following in my code:

String agentKey = new String("agent_"+agent);

PublishKey pk = new PublishKey(glob, oid, "text/xml", "1.0");
pk.setClientTags("<org.xmlBlaster><demo/><" + agentKey +
">test</" +
agentKey + "></org.xmlBlaster>"); 

This gets a tag set for agent_1000 above...

I subsequently publish the message.

Now, in my GUI/receiver I sign in as agent 1000, like this:

			sk =
				new SubscribeKey(
					glob,"//*[contains(name(),'agent_"+
myClient.getJTextField().getText()+ "')]",
					Constants.XPATH);


which sets my xpath filter to:
<key queryType='XPATH'>
 //*[contains(name(),'agent_1000')]
</key>


The messages don't arrive...  So, does an Xpath filter apply to the
clienttags?  I thought it applied to the entire message, but maybe it's just
the content?

This works fine here:

1. Start xmlBlaster:

 java org.xmlBlaster.Main -call[core] true


2. Do a 'cvs update -dP' and compile xmlBlaster to get the new HelloWorldPublish
which now allows to set the client tags from command line:

java javaclients.HelloWorldPublish -clientTags "<org.xmlBlaster><demo/><agent_1000>test</agent_1000></org.xmlBlaster>"

  (and hit a key to publish)

3. Start the subscriber

java javaclients.HelloWorldSubscribe -xpath "//*[contains(name(),'agent_1000')]"

 (and hit a key to subscribe)

and it works as expected.

PS: The XPath is only checking the message key.
PPS: We have plugins for REGEX and XPATH to further filter using message contents.
