Hi all,

I am on a project which want to get data from "show subscribers summary port" command. I wrote a script to do that but it getting not enough data.

Here are the script: 

version 1.0;
ns Junos = "http://xml.juniper.net/junos/*/junos";
ns xnm = "http://xml.juniper.net/xnm/1.1/xnm";
ns jcs = "http://xml.juniper.net/junos/commit-scripts/1.0";

match / {
	<op-script-results> {
	var $cmd = <command> "show subscribers summary port";
    var $results = jcs:invoke($cmd);
	
	for-each ( $results/counters/port-name ) {
		<output> "The number subscribers of interface "_ . _ " is " _ ../port-count;
		}
	}
}

 and this is the output when run this script:

datnt@juniper> op sub  
The number subscribers of interface xe-0/2/1 is 5916
The number subscribers of interface xe-11/0/1 is 5916
The number subscribers of interface xe-11/1/1 is 5916

 The output of script dont match the output of command. I am very pleasure if anyone can help me fix it .

Here are the output of the command:

datnt@juniper> show subscribers summary port    
Interface           Count 
xe-0/2/1            5916               
xe-11/0/1           10121              
xe-11/1/1           2544               

datnt@juniper> show subscribers summary port | display xml 
<rpc-reply xmlns:junos="http://xml.juniper.net/junos/11.4X27/junos">
<subscribers-summary-information xmlns="http://xml.juniper.net/junos/11.4X27/junos-subscribers">
 <counters junos:style="port-summary">
     <port-name>xe-0/2/1</port-name>
     <port-count>5916</port-count>
     <port-name>xe-11/0/1</port-name>
     <port-count>10122</port-count>
     <port-name>xe-11/1/1</port-name>
     <port-count>2544</port-count>
 </counters>
<counters junos:style="port-summary-total">
<port-total>18578</port-total>
</counters>
</subscribers-summary-information>
<cli>
<banner>{master}</banner>
</cli>
</rpc-reply>

It's unfortunate that the XML results are structured in that way. Ideally you'd want each matching port-name and port-count to be segmented in a separate hierarchy. But, with the hierarchy shown in your results, you'll need to make use of the following-sibling axis rather than the parent/child axes.

<output> "The number subscribers of interface "_ . _ " is " _ ./following-sibling::port-count[1];

Please give that a try.

Thanks

Thank ccall for your help. It's work.
I have a another question want to ask. How can i get data from $results/counters/ and put it on a variable to use for other purposes.
In this example, i want the result of variable x = "xe-0/2/1 5916 xe-11/0/1 10121 xe-11/1/1 2544"

You can enclose the for-each loop within a variable and build the output (note that this will catch all output, including XML elements like <output>):

var $variable = {

    for-each( ...whatever your path is... ) {

        expr ...whatever you want to write...;

    }

}

Hi ccall,

Can you help me on this case?

Try this:

var $text = {

    for-each ( $results/counters/port-name ) {

        expr . _ " " _ ./following-sibling::port-count _ "\n";

    }

}

It's work great. Thank you very much!
