#112: How to handle xml document in Powershell?

 In PowerShell, you can handle XML data using various cmdlets and methods provided by the .NET Framework. Here's a basic guide on how to handle XML with PowerShell:

Loading XML Data:

You can load XML data from a file or a string using the Get-Content cmdlet and then convert it to an XML object using the Select-Xml cmdlet or the [xml] type accelerator.

Example:

# Load XML from a file

$xmlContent = Get-Content -Path "C:\path\to\file.xml"

# Convert XML content to an XML object

$xmlObject = [xml]$xmlContent

Accessing XML Elements and Attributes:

You can access XML elements and attributes using dot notation or by using XPath expressions.

Example:

# Access elements using dot notation

$elementValue = $xmlObject.Root.Element.SubElement.InnerText

# Access elements using XPath

$elementValue = $xmlObject.SelectSingleNode("/Root/Element/SubElement").InnerText

Modifying XML Data:

You can modify XML data by assigning new values to elements and attributes.

Example: 

# Modify element value

$xmlObject.Root.Element.SubElement.InnerText = "New Value"

# Add new element

$newElement = $xmlObject.CreateElement("NewElement")

$newElement.InnerText = "New Element Value"

$xmlObject.Root.Element.AppendChild($newElement)

Saving XML Data:

You can save modified XML data to a file using the Save method.

Example: 

$xmlObject.Save("C:\path\to\modified_file.xml")

Example:

Here's a simple example demonstrating loading XML from a file, accessing elements, modifying data, and saving the changes:

Example: 

# Load XML from a file

$xmlContent = Get-Content -Path "C:\path\to\file.xml"

$xmlObject = [xml]$xmlContent

# Access and modify XML data

$xmlObject.Root.Element.SubElement.InnerText = "New Value"

# Save modified XML to a new file

$xmlObject.Save("C:\path\to\modified_file.xml")

This example showcases some common operations you can perform with XML data in PowerShell. Depending on your specific requirements, you can use additional cmdlets and methods to handle XML data effectively.
