linq-to-xml

问题 i'm parsing a few .net resource files (.resx). In that, i have this piece of data: información This works in my .net app, but when i try to load this file in my xml document XDocument xmlDoc = XDocument.Parse(s); i get this error: Reference to undeclared entity 'oacute'. Why is that? 回答1: ó is a named HTML entity that is not defined in XML. XML only defines a subset of the named HTML entities (namely & , &apos; , " , > and < if memory serves). You can use the numeric entity representation

问题 I'm learning LINQ to XML and need to find the existence of an element with a particular attribute. At the moment I'm using: XElement groupCollectionXml = XElement.Parse(groupCollection.Xml); IEnumerable<XElement> groupFind = from vw in groupCollectionXml.Elements("Group") where (string) vw.Attribute("Name") == groupName select vw; if (groupFind.Count() == 0) return false; else return true; I know there is a more concise way of doing this, probably using Any(), but I'm not sure how to rewrite

问题 I am trying to load an xml file that is stored as a resource in my C# project so I can perform various LINQ queries. However at runtime an "Illegal characters in path" exception is thrown. This is how I am loading the file: XDocument doc = XDocument.Load(MyProject.Properties.Resources.XMLFile); 回答1: Wouldn't XMLFile here actually return the xml itself? If so: XDocument doc = XDocument.Parse(MyProject.Properties.Resources.XMLFile); 来源： https://stackoverflow.com/questions/337535/reading-xml

问题 Now I will start off by saying this is indeed an assigment. I have however nearly finished it untill I ran into the Linq to XML syntax. I have 2 classes: Track and CD now as part of the assigment I create a cd and then added some tracks to it. After searching for lots of tutorials that explained perfectly how to go from xml to objects I just cannot seem to get this working (objects to xml). I currently have: //My list of cds List<CD> cds = new List<CD>(); //Make a new CD and add some tracks

问题 I have a single XElement looking like this: <row flag="1" sect="" header="" body="" extrainfo="0" /> Then I have a class looking like this: public class ProductAttribute { public string Flag { get; set; } public string Sect { get; set; } public string Header { get; set; } public string Body { get; set; } public string Extrainfo { get; set; } } How can I convert this XElement into a ProductAttribute object? 回答1: You have to put the correct serialization attributes on your class and class

问题 I've looked at Nodes() vs DescendantNodes() usages? to see the difference between .Nodes() and .DescendantNodes() but what is the difference between: XDocument.Descendants() and XDocument.DescendantNodes()? var xmlDoc = XDocument.Load(@"c:\Projects\Fun\LINQ\LINQ\App.config"); var descendants = xmlDoc.Descendants(); var descendantNodes = xmlDoc.DescendantNodes(); foreach (var d in descendants) Console.WriteLine(d); foreach (var d in descendantNodes) Console.WriteLine(d); 回答1: Descendants

问题 I'm parsing an XLIFF document using the XDocument class. Does XDocument perform some validation of the content which I read into it, and if so - is there any way to disable that validation? I'm getting some weird errors if the XLIFF isn't valid XML (I don't care that it isn't, I just want to parse it). E.g. '.', hexadecimal value 0x00, is an invalid character. I'm currently reading the file like this: string FileLocation = @"C:\XLIFF\text.xlf"; XDocument doc = XDocument.Load(FileLocation);

问题 My current LINQ query and example XML are below. What I'd like to do is select the primary email address from the email-addresses element into the User.Email property. The type element under the email-address element is set to primary when this is true. There may be more than one element under the email-addresses but only one will be marked primary. What is the simplest approach to take here? Current Linq Query (User.Email is currently empty): var users = from response in xdoc.Descendants(

问题 Using this example how would I go about updating an XML file using this example: <foo> <n1> <s1></s1> <s2></s2> <s3></s3> </n1> <n1> <s1></s1> <s2></s2> <s3></s3> </n1> </foo> I Can read from it all day long but for the life of me I cannot seem to write it back into that format. 回答1: Straightforward approach: ' to create the XmlDocument... ' Dim xmlDoc As New Xml.XmlDocument Dim fooElement As Xml.XmlElement = xmlDoc.CreateElement("foo") xmlDoc.AppendChild(fooElement) Dim n1Element As Xml
