Import only select data from json to powershell - json

Question

I want to Import selected data from Json url and so I can convert it to XML.
I am using following code to import.
(Invoke-RestMethod -URI "http://www.broadbandmap.gov/broadbandmap/broadband/dec2013/wireline?latitude=29.488412&longitude=-98.550208&format=json").Results.wirelineServices.providerName | Select-Object | Format-Table –AutoSize
so I am using .Results.wirelineServices.providerName to pull selected columns from one branch/table.
how can I pull data from .Results.broadbandSource.stateFips also at same time?
Thanks bunch.

Answer 1

I think that you should separate out your steps a bit:
$r = Invoke-RestMethod -URI "http://www.broadbandmap.gov/broadbandmap/broadband/dec2013/wireline?latitude=29.488412&longitude=-98.550208&format=json"
$providers = $r.Results.wirelineServices.providerName
$stateFips = $r.Results.broadbandSource.stateFips
Note that in your example, your call to Select-Object is redundant (you're not selecting anything, so it's not changing the input object).
Also, a very important point about Format-Table (and any Format- cmdlet) is that those are for display only so they should always be the last thing you do, if in fact they're needed at all.
The code I've given gives you the information in objects, which you can then work with, filter or, display as needed. I'm not sure how you wanted to use/display it, but since there are multiple providers and only one stateFips value, I might assume that you would apply the Fips value to each provider. Here's an example of that which uses the $stateFips variable we created:
$r.Results.wirelineServices | Select-Object providerName,#{Name='stateFips' ; Expression={ $stateFips }}
And here's an example that uses only the original result $r:
$r.Results.wirelineServices | Select-Object providerName,#{Name='stateFips' ; Expression={ $r.Results.broadbandSource.stateFips }}
The Select-Object computed column syntax
Note that the second column definition looks a bit wonky. It's actually a hashtable that allows you to specify the name of the column, and an expression (a complete code block) whose return value will be the value of the column. It could be spread over multiple lines like this:
$r.Results.wirelineServices | Select-Object providerName,#{
Name = 'stateFips'
Expression = {
$r.Results.broadbandSource.stateFips
}
}
Or you could even create the hashtable as a variable first:
$computed = #{
Name = 'stateFips'
Expression = {
$r.Results.broadbandSource.stateFips
}
}
$r.Results.wirelineServices | Select-Object providerName,$computed
XML?
#Stephen Connolly's answer reminded me that you wanted to make XML out of this. Let's take the above code and assign it to a variable:
$computed = #{
Name = 'stateFips'
Expression = {
$r.Results.broadbandSource.stateFips
}
}
$data = $r.Results.wirelineServices | Select-Object providerName,$computed
Because $data is still an object and wasn't sent through a Format- command, we can still use it!
$xml = $data | ConvertTo-Xml -NoTypeInformation
As his comment also suggested though, we don't know how you wanted the resultant XML to be formatted.
So here's another approach:
Forget the JSON
$r = Invoke-RestMethod -URI "http://www.broadbandmap.gov/broadbandmap/broadband/dec2013/wireline?latitude=29.488412&longitude=-98.550208&format=xml"
Now $r contains XML already. You can filter it out and modify it using XPATH. I won't get into that at the moment unless you think that way would work better for you.
Hope this helps, let me know if I've misunderstood what you're trying to do here.

If you want a composite object try something like
$results = (Invoke-RestMethod -URI "http://www.broadbandmap.gov/broadbandmap/broadband/dec2013/wireline?latitude=29.488412&longitude=-98.550208&format=json")
$obj = $results.Results.wirelineServices
$obj | add-member -type noteproperty -Name StateFips -Value $($results.Results.broadbandSource.stateFips) -PassThru
$obj | convertto-xml -as string
