[j-nsp] read CLI "banner" XML element value with SLAX script

[Martin T]

Hi,

Junos has "banner" XML element under "rpc-reply" and "cli" hierarchy:

<rpc-reply>
  <cli>
    <banner></banner>
  </cli>
</rpc-reply>

Is it somehow possible to read the value of "banner" element with SLAX
script? For example I have a router with dual routing-engines, i.e
"banner" element has either value of "{master}" or "{backup}":

{master}
root at M10i> show version brief | display xml | find cli
    <cli>
        <banner>{master}</banner>
    </cli>
</rpc-reply>

{master}
root at M10i>


Now if I try to print the value of "banner" element, then this does not work:


{master}
root at M10i> file show /var/db/scripts/op/show-banner.slax
version 1.0;

ns jcs = "http://xml.juniper.net/junos/commit-scripts/1.0";

match / {
  <op-script-results> {
    var $sh_ver_cmd = <command> "show version brief";
    var $sh_ver_cmd_out = jcs:invoke( $sh_ver_cmd );
    var $banner_var = $sh_ver_cmd_out//banner;
    <output> $banner_var;
  }
}

{master}
root at M10i> op show-banner


{master}
root at M10i>


Is there a way to process everything between <rpc-reply></rpc-reply>
elements? I'm afraid that my script processes data between
<software-information> and </software-information> elements.


thanks,
Martin
