NQE Validate DNS Configuration on Arista & Cisco

Audit our DNS configuration on Arista Devices and Cisco Devices - Would like to be able to combine the script as a single check, and started it (Second Code Script), but it’s not working yet, I need a little tutoring. 

/**
 * @intent Audit DNS Configuration on Arista
 * @description Searches through the running configuration for a pattern match.
 */

DNS_Standard = d"name-server 1.7.7.7 & 1.7.7.8", "dns domain net.xyz.com ",  "ip domain lookup source-interface Loopback0"];

AristaPatternDNS =
```
ip domain lookup source-interface Loopback0
dns domain net.xyz.com
ip name-server vrf default {ipv4Address} 
ip name-server vrf default {ipv4Address} 
```;

/* Select a list of devices by vendor */
foreach device in network.devices
where device.platform.vendor == Vendor.ARISTA || device.platform.os == OS.ARISTA_EOS
let outputs = device.outputs
foreach command in outputs.commands
where command.commandType == CommandType.CONFIG
let response = command.response
/* parse out the pattern defined above from the response of the CONFIG command type. */
let config = parseConfigBlocks(OS.ARISTA_EOS, response)
foreach match in blockMatches(config, AristaPatternDNS)

/* Display the results */
select {
  Device: device.name,
  Model: device.platform.os,
  Pattern: DNS_Standard,
  matchedBlocks: match.blocks
}

Here is the start of something that might work in the future - If someone can figure out how to duplicate the above for multiple Vendors:

MULTIPLE VENDOR “IDEA”

/** Same as ver1 but with an Import DNS_HOSTS from NetworVars/DNS_Servers File - **/
/** Want to be able to get a single DEVICE OUTPUT, why am I getting doubles???? **/
/** **//** **//** **//** **//** **//** **//** **//** **//** **//** **/
