linq-to-xml

问题 I am creating a List of structs using linq to xml. The linq path does not find the concept elements. I have tried various formulations of this and before I give up and use xpath I am hoping someone can show me the linq way. thanks Here is the xml <response xmlns="http://www.domain.com/api"> <about> <requestId>E9B73CA1F16A670C966BE2BABD3B2B22</requestId> <docId>09E167D994E00B0F511781C40B85AEC3</docId> <systemType>concept</systemType> <configId>odp_2007_l1_1.7k</configId> <contentType>text

问题 flow.Name definitely equals the 'name' of one of the flows in the flowData XDocument. XElement rootelem = flowData.Root.Element("flows"); after the above line the rootelem contains the flows element and it's children as expected BUT the below line throws a null reference exception, why? flowData.Root.Element(flow.Name).Remove(); flowData is declared as an XDocument and looks like so: <?xml version="1.0" encoding="UTF-8"?> -<D53ESB> -<comms> <diagnosticemails sender="eventlog"/> </comms> -

问题 Here is my XML <assets> <asset> <metadata Id="ItemType" Value="Image"/> <metadata Id="ItemUri" Value="http://blah.png"/> </asset> <asset> <metadata Id="ItemType" Value="Image"/> <metadata Id="ItemUri" Value="http://blah2.png"/> </asset> </assets> How do I get the 2nd <metadata> 's value containing the URI? List<Asset> assets = (from asset in xmlDocument.Descendants("asset") select new Asset { ItemType = asset.Element("metadata").Attribute("Value").Value, ItemUri = asset.Element("metadata")

问题 I want to make it so the item I have selected in the list box shows its sibling elements in labels. Currently I used my XML file to get the <Name> element and populate my list box with these <Name> values. Now I want to make it so that whenever the <Name> is highlighted in the list box, it will show the <Code> related to that module in a label on the form. i.e. If in the List Box, Algorithms and Data Structures is selected, show its Code,Capacity,Semester and Prerequisites in labels on the

问题 I have spent the last few days reading here on Stack Overflow, blogs, and MSDN articles. I am clearly lacking some basic understanding of how namespaces, Linq, and XML work and am in need of help. If I had more hair to pull out, it would be in my hand right now :-) Using C# and Linq to XML, I open the following opf.xml file: <?xml version="1.0" encoding="UTF-8"?> <package version="2.0" xmlns="http://www.idpf.org/2007/opf" unique-identifier=""> <metadata xmlns:dc="http://purl.org/dc/elements/1

问题 i have this piece of code which i use to add some elements: string xmlTarget = string.Format(@"<target name='{0}' type='{1}' layout='${{2}}' />", new object[] { target.Name, target.Type, target.Layout }); Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); var xmlDoc = XElement.Load(configuration.FilePath); var nlog = xmlDoc.Elements("nlog"); if (nlog.Count() == 0) { return false; } xmlDoc.Elements("nlog").First().Elements("targets").First()
