[xmlblaster] Xpath problem with filter...

["Valerio Parola" <v.parola at kline.it>]

I need help.
I like to make a subscribe with a xpath filter to extract all message with a
particular tag.
My messages have this structure:

<key oid='pub'>
    <prova name='a different name'/>
</key>
<qos>
....
</qos>

or

<key oid='bar'>
    <prova name='a different name'/>
</key>
<qos>
....
</qos>

I subscribed this message:

<key oid='' queryType='XPATH'>
//key/prova[ at name='my name']
</key>
<qos><history numEtries='-1'/> </qos>

The server answers with all messages of the one subscribed  topic, but
I need every messages from every topic but with a specific name attribute in
the tag prova.
I can't understand what is my mistake?
Thank you!
Valerio
