Automation

Created this function, but it's returning an empty string.

Running through juice the file is transfered, and read, but doesn't make it into the results.

<func:function name="common:read-file-contents">
{
        param $jre;
        param $ftp-server;
        param $file-name;

        var $remote-file = "ftp://user:pw@" _ $ftp-server _ "/" _ $file-name;
        var $local-file = "/var/tmp/" _ $file-name;
        var $rpc-copy = <file-copy> {
                                        <source> $remote-file;
                                        <destination> $local-file;
                                }
        var $rslt-copy = jcs:execute($jre, $rpc-copy);

        var $rpc-show = <file-show>{
                                        <filename>$local-file;
                                }
        var $rslt-show = jcs:execute($jre, $rpc-show);

        <func:result select="string($rslt-show//file-content)">;
}

The response is:

<rpc-reply xmlns:junos="http://xml.juniper.net/junos/11.2R2/junos">
    <file-content filename="/var/tmp/current.version" junos:seconds="1363741717" filesize="9" encoding="text">
        12.1R4.7
    </file-content>
    <cli>
        <banner></banner>
    </cli>
</rpc-reply>

Any ideas?

Have you tried using <file-get> in place of <file-show> ? 

I use the <file-get> in my programs, but haven't used <file-show>.  I think there is a good explanation of the difference in the Day One Book: "Mastering Junos Automation Programming", section "File I/O: Reading".  URL here.

        var $rslt-show = jcs:execute($jre, $rpc-show);

        <func:result select="string($rslt-show//file-content)">;

 

 

The context node of the <file-show> result will be <file-content>, so you don't want to include it in your location path:

 

        <func:result select="$rslt-show">;
