Just run into the same problem myself, and workaround is here:
you can use local-name() function to do namespace-agnostic 
searches, and you can use partial checks on namespaces to be
sure that you getting what you want. 

Example: iterate over physical interfaces:  

    <xsl:for-each select="//*[local-name()='physical-interface' and 
        starts-with(namespace-uri(), 'http://xml.juniper.net/junos/')]">

Select operational state: 

        <xsl:variable name="oper"
            select="normalize-space(*[local-name()='oper-status'])"/>

Select dropped packets for first queue: 

        select="normalize-space(*[local-name()='queue-counters']/*[local-name()='queue' and *[local-name()='queue-number']=0]/*[local-name()='queue-counters-red-packets'])"/>


Syntax is ugly, but it works...
