问题 I'm trying to parse results from the YouTube API. I'm getting the results correctly as a string, but am unable to parse it correctly.

问题 I have a XML file like that: <Users> <User> <Adress Name="bbbb"/> <Adress Name="aaaa" /> </User> </Users> I want to sort User element's nodes in ascending order. How can I order Adress elements?

This code shows reordering the elements within an

问题 I wrote some code in VB.Net a while ago that is using XElement, XDocument, etc... to store and manipulate HTML. Some of the HTML makes use of attribute names that contain a hyphen/dash (-). I encountered issues using LinqToXml to search for XElements by these attributes. Back then I found an article (can't find it now) that indicated the solution in VB.net was to use syntax like this: Dim rootElement as XElement = GetARootXElement() Dim query = From p In rootElement.<div> Where p.@<data-qid>

问题 I'm trying to find the inner text value of an element using LINQ-to-XML (an XElement object). I make my service call and get an XML response back that I've successfully loaded into an XElement object. I want to extract the inner text of one of the elements - however, every time I try to do this, I get a null result. I feel like I'm missing something super-simple, but I'm fairly new to LINQ-to-XML. Any help is appreciated. I'm trying to get the inner text value of the StatusInfo/Status element

问题 I have an app which should read the data from an xml file and then use that data. How can I import an xml file in my app (what's the code for that) and how can I use the data from that xml file?
