Advanced XML Query Question

[cwhelan]

When I walk my CMTS (Arris C4) I get the following format:
snmpwalk -v 1 -c 'pass' ip 1.3.6.1.4.1.4998.1.1.20.2.12.1.6

SNMPv2-SMI::enterprises.4998.1.1.20.2.12.1.6.918032.918097 = INTEGER: 113

Here is my question... I know how to create the XML snmp query, however, the last two numbers are the "variables" that I'm struggling with. Basically, the 918032 is the defined "Downstream" and the last number is the Indexed number I'm after the results for. Basically, I already have a script and it gets other data, but when it runs agains this OID, it looks like this:

1.3.6.1.4.1.4998.1.1.20.2.12.1.6.918097
1.3.6.1.4.1.4998.1.1.20.2.12.1.6.ifUpstreamID

When it needs to be:

1.3.6.1.4.1.4998.1.1.20.2.12.1.6.918032.918097
1.3.6.1.4.1.4998.1.1.20.2.12.1.6.ifDownstreamID.ifUpstreamID

I know it seems easy, but the 918032 number changes depending on the interface. Is there a way to "Wildcard" that specific spot so that I only get the results for the Interface (there will only ever be one "last" number, but multiple 2nd to last numbers)?[/b]

So what abount defining a two-dimensional index, holding the last two indices as a whole? This should be unique and so be acceptable as an index. Please try searching the forums. I've already answered this more than once, but it's a bit tricky. You need a VALUE/REGEXP that catches the last two indices
