HowTo: Writing XML Files Tuesday, July 15, 2008 2:38 AM (permalink)

There's not a lot of comments in this example. Instead, there is a decent amount of clean code that shows you how it's done. Also consider reading http://www.w3schools.com/xml/default.asp

cls
 [xml] $xmlLog = '<?xml version="1.0" encoding="ISO-8859-1"?> <Bakery_Inventory><x /></Bakery_Inventory>';
 
 # Generate Run Details
 $xmlRunDetails = $xmlLog.CreateElement("Run_Details");
 
 $xmlTimeStamp = $xmlLog.CreateElement("TimeStamp");
 ($xmlTimeStamp.AppendChild(($($xmlLog.CreateElement("Year"))))).psBase.InnerText = Get-Date -UFormat %Y;
 ($xmlTimeStamp.AppendChild(($($xmlLog.CreateElement("Month"))))).psBase.InnerText = Get-Date -Format %M;
 ($xmlTimeStamp.AppendChild(($($xmlLog.CreateElement("Day"))))).psBase.InnerText = Get-Date -Format %d;
 ($xmlTimeStamp.AppendChild(($($xmlLog.CreateElement("Time"))))).psBase.InnerText = Get-Date -UFormat %T;
 $Catch_Output = $xmlRunDetails.AppendChild($xmlTimeStamp);    # Catching the output seems necessary to keep PowerShell from dumping information to the screen
 $Catch_Output = $xmlLog.Bakery_Inventory.AppendChild($xmlRunDetails);
 
 $xmlCookie = $xmlLog.CreateElement("Cookie");
 ($xmlCookie.AppendChild(($($xmlLog.CreateElement("Name"))))).psBase.InnerText = "Chocolate Chip";
 ($xmlCookie.AppendChild(($($xmlLog.CreateElement("Path"))))).psBase.InnerText = "Assembly Line 1";
 
 $intCounter = 1;
 $xmlSample = $xmlLog.CreateElement("Random_Sample");
 $xmlSample.SetAttribute("ID",[string]$intCounter);
 ($xmlSample.AppendChild(($($xmlLog.CreateElement("Oven_Name"))))).psBase.InnerText = "Bloodgett_1";
 ($xmlSample.AppendChild(($($xmlLog.CreateElement("Chocolate_Chip_Count"))))).psBase.InnerText = $(New-Object System.Random).next(1,10000);
 ($xmlSample.AppendChild(($($xmlLog.CreateElement("Diameter"))))).psBase.InnerText = $(New-Object System.Random).next(1,10000000);
 $Catch_Output = $xmlCookie.AppendChild($xmlSample);
 
 $intCounter += 1;
 $xmlSample = $xmlLog.CreateElement("Random_Sample");
 $xmlSample.SetAttribute("ID",[string]$intCounter);
 ($xmlSample.AppendChild(($($xmlLog.CreateElement("Oven_Name"))))).psBase.InnerText = "Bloodgett_1";
 ($xmlSample.AppendChild(($($xmlLog.CreateElement("Chocolate_Chip_Count"))))).psBase.InnerText = $(New-Object System.Random).next(1,10000);
 ($xmlSample.AppendChild(($($xmlLog.CreateElement("Diameter"))))).psBase.InnerText = $(New-Object System.Random).next(1,10000000);
 $Catch_Output = $xmlCookie.AppendChild($xmlSample);
 
 $Catch_Output = $xmlLog.Bakery_Inventory.AppendChild($xmlCookie);
 
 $xmlLog.Save((join-path -path $(get-location).tostring() xmlBakery.txt));
 Get-Content (join-path -path $(get-location).tostring() xmlBakery.txt);

The output is this:

<?xml version="1.0" encoding="ISO-8859-1"?>
 <Bakery_Inventory>
   <x />
   <Run_Details>
     <TimeStamp>
       <Year>2008</Year>
       <Month>7</Month>
       <Day>15</Day>
       <Time>10:35:58</Time>
     </TimeStamp>
   </Run_Details>
   <Cookie>
     <Name>Chocolate Chip</Name>
     <Path>Assembly Line 1</Path>
     <Random_Sample ID="1">
       <Oven_Name>Bloodgett_1</Oven_Name>
       <Chocolate_Chip_Count>4810</Chocolate_Chip_Count>
       <Diameter>4810210</Diameter>
     </Random_Sample>
     <Random_Sample ID="2">
       <Oven_Name>Bloodgett_1</Oven_Name>
       <Chocolate_Chip_Count>3174</Chocolate_Chip_Count>
       <Diameter>3174007</Diameter>
     </Random_Sample>
   </Cookie>
 </Bakery_Inventory>
