I ended up writing two versions of my script. The first is a traditional script, and the second is a script file that contains only the function itself. If I configure the function as a Windows PowerShell script, I have to add command line parameters to allow for flexibility. The Get-UsGovWeather.ps1<\/b> script is seen here.<\/p>\n

Of course, if you want to compare the weather from your home with that of another location, use the up arrow, and add the -zip<\/i> parameter. To view the weather for more than the default three days, use the -numberdays<\/i> parameter. The commands and the associated outputs are seen in the following figure.<\/p>\n <\/p>\n Most of the time I will be using the Get-UsGovWeather <\/b>function inside my Windows PowerShell ISE. Because the function returns an object, the output can be easily sorted and arranged by using Windows PowerShell cmdlets. The problem is that is too much work when all one wants to do is to get a quick weather forecast. The solution is twofold. First, I store the function in a .ps1 script file that is kept in my ISEProfileModule folder. The function is only the function code, without any default values and without any formatting. A good function returns a rich object that can be processed later as required. The behavior is like a Windows PowerShell cmdlet. The Get-UsGovWeather<\/b> function is seen here.<\/p>\n Get-UsGovWeather<\/strong><\/p>\n Function Get-UsGovWeather<\/span><\/p>\n {<\/span><\/p>\n Param([string]$zip,<\/span><\/p>\n [int]$numberDays<\/span><\/p>\n )<\/span><\/p>\n $URI = “http:\/\/www.weather.gov\/forecasts\/xml\/DWMLgen\/wsdl\/ndfdXML.wsdl”<\/span><\/p>\n $Proxy = New-WebServiceProxy -uri $URI -namespace WebServiceProxy<\/span><\/p>\n [xml]$latlon=$proxy.LatLonListZipCode($zip)<\/span><\/p>\n foreach($l in $latlon)<\/span><\/p>\n {<\/span><\/p>\n $a = $l.dwml.latlonlist -split “,”<\/span><\/p>\n $lat = $a[0]<\/span><\/p>\n $lon = $a[1]<\/span><\/p>\n $sDate = get-date -UFormat %Y-%m-%d<\/span><\/p>\n $format = “Item24hourly”<\/span><\/p>\n [xml]$weather = $Proxy.NDFDgenByDay($lat,$lon,$sDate,$numberDays,$format)<\/span><\/p>\n For($i = 0 ; $i -le $numberDays -1 ; $i ++)<\/span><\/p>\n {<\/span><\/p>\n New-Object psObject -Property @{<\/span><\/p>\n “Date” = ((Get-Date).addDays($i)).tostring(“MM\/dd\/yyyy”) ;<\/span><\/p>\n “maxTemp” = $weather.dwml.data.parameters.temperature[0].value[$i] ;<\/span><\/p>\n “minTemp” = $weather.dwml.data.parameters.temperature[1].value[$i] ;<\/span><\/p>\n “Summary” = $weather.dwml.data.parameters.weather.”weather-conditions”[$i].”Weather-summary”}<\/span><\/p>\n } <\/span><\/p>\n }<\/span><\/p>\n } #end function Get-UsGovWeather<\/span><\/p>\n <\/p>\n This folder is seen in the following figure.<\/p>\n <\/p>\n After the function is stored in my profile module location, I then create a short function in my Windows PowerShell ISE profile to display only the weather configuration I want. The function that I put in my Windows PowerShell ISE profile is seen here.<\/p>\n Function Get-MyWeather <\/p>\n The Windows PowerShell ISE profile is seen in the following figure.<\/p>\n <\/p>\n The cool thing is that the weather is now immediately available. I type get-MyWeather<\/b> (actually I type get-my and press <tab> to retrieve the current weather. The output is shown in the following figure.<\/p>\n <\/p>\n Well, that is about it for messing around with web services, and the Windows PowerShell ISE profile. Join me tomorrow as I begin talking about object member discovery. It should be a very good week. <\/p>\n <\/p>\n I invite you to follow me on Twitter<\/a> or Facebook<\/a>. If you have any questions, send email to me at scripter@microsoft.com<\/a> or post them on the Official Scripting Guys Forum<\/a>. See you tomorrow.
