How to Convert and Parse XML to String in PowerShell
Working with XML data can often be a daunting task, especially when you need to convert or parse it into various formats for processing. PowerShell provides robust capabilities for converting XML data to strings, parsing XML nodes to strings, and even converting entire XML files into string arrays. This post will guide you through these processes, demonstrating how to handle XML data effectively using PowerShell.
PowerShell: Convert XML to String
The most straightforward way to convert an XML document to a string in PowerShell is by loading the XML into an XmlDocument object and then using the OuterXml property to get the string representation.

This method ensures that the entire XML is transformed into a single string, maintaining the structure and format of the XML data.
Parsing XML to String in PowerShell
Parsing XML data involves reading specific elements or nodes and converting them into strings. You can achieve this by navigating through the XML nodes using properties or methods available in the XmlDocument object.

In this example, SelectSingleNode is utilized to fetch a specific node (TargetNode) from the XML document, and InnerXml is used to convert that node to a string.
Converting an XML Node to String
Similar to parsing, converting a specific XML node to a string can be done by directly addressing the node and using its properties. This method is particularly useful when dealing with segments of an XML document that need individual processing.

Here, DocumentElement.ChildNodes[0] selects the first child node of the root element, and OuterXml converts the entire node to a string.
Converting XML to String Array in PowerShell
For scenarios where you need the XML data in a line-by-line string array format, PowerShell allows you to split the XML string based on line breaks.

By first converting the XML to a single string (OuterXml) and then splitting it by newline characters (-split "n"`), you will get an array where each line of the original XML string is an array element.
Conclusion
PowerShell provides flexible and powerful methods to work with XML data, whether you need to convert an entire XML document to a string, parse specific nodes, or transform XML data into a string array. Mastering these techniques allows for efficient and precise handling of XML data in a variety of PowerShell scripts and automation tasks.
By utilizing properties like OuterXml and methods like SelectSingleNode, you can easily and effectively manage your XML data directly within PowerShell.
