Second, I will likely keep coming back here from time to time as it is a great repository and a good place to refresh my memory when I am looking to do stuff. One thing missing that can be difficult to find I am looking for it now , is how to take a node and convert its children to attributes, and the reverse. Thanks again!

The root node for this particular document is Locations , which hold two other nodes Location and each location node holds area nodes. Text can be a node type like "Magic Kingdom.

Element - An element is a type of node and includes everything inbetween the beginning tag to the ending tag. For example, the first element under the first Location element is Magic Kingdom. How do you load XML? There are multiple ways to load an XML document. One way is to create the XML document from a string. LoadXml xml ; Another way is to load it through a file. Load "C: How do you create an XDocument "document? To set all of the descendants to a namespace, set their localname to the namespace.

Add new XAttribute XNamespace. This will grab all of the attractions throughout the entire Xml document.

This gets a little trickier as we dig down into the XML document. First, you need to get the parent element Location. Elements "Location".


Element "Title". Elements "Area".

Elements "Attractions". Elements "Attraction". How do you return sorted elements?
