powershell xml memory-management PowerShell

I'm trying to figure out I'm working on a personal project and I'm currently working on a PowerShell script that needs to parse a large XML file (about 500 MB) to extract specific nodes and attributes... However, when I attempt to load the entire XML file into memory using `Get-Content` and `ConvertFrom-Xml`, PowerShell crashes with an `OutOfMemoryException`. I've tried using `StreamReader` to handle the file in chunks, but I'm having trouble modifying the script to accommodate that approach. Here's a snippet of what I was working with: ```powershell $xmlPath = 'C:\path\to\largefile.xml' $xmlContent = Get-Content -Path $xmlPath -Raw | ConvertFrom-Xml # Attempt to get specific nodes $desiredNodes = $xmlContent.Document.Node | Where-Object { $_.Attribute -eq 'SomeValue' } ``` When I run the script, it fails at the `ConvertFrom-Xml` line. I thought about using `Select-Xml`, but I'm not sure how to properly filter and extract the required nodes without loading the entire file into memory. Can anyone suggest an efficient way to handle this in PowerShell without running into memory issues? Any help or insights into handling large XML files effectively would be greatly appreciated! This is part of a larger API I'm building. This is for a desktop app running on Windows 10. How would you solve this?
