Using hashtables to combine values

For a job I needed a good way of combining a primary value with optional subvalues in a xml-file.
Below is an example of how to extract attributes from a xmlelement into a hashtable and then join two hashtables into one. I couldn't find a method for extracting elements on the web, folks usually goes with subnodes instead of attributes. I'm partial to attributes and had to get creative, but the solution was quite simple. The Attributes from the element only show the actual elements from the xmlfile. Its not obvious when browsing the object that -name property can be lifted, but here it's used for creating a new hashtable-row



Samplescript for proof of concept


This eventually led to createwebsFromStructure.ps1 that uses powershell splatting to build commands with the resulting hashtable.
