由 吃可爱长大的小学妹 提交于 2019-11-28 08:07:21
I am writing some data to XML file...but when I open it all the values are in a single line...how can write it in readable format?ie each node in new line and indentation? FileStream fs = new FileStream("myfile.xml", FileMode.Create); XmlWriter w = XmlWriter.Create(fs); w.WriteStartDocument(); w.WriteStartElement("myfile"); w.WriteElementString("id", id.Text); w.WriteElementString("date", dateTimePicker1.Text); w.WriteElementString("version", ver.Text); w.WriteEndElement(); w.WriteEndDocument(); w.Flush(); fs.Close(); Use a XmlTextWriter instead of XmlWriter and then set the Indentation

How to create a XmlDocument using XmlWriter in .NET?

由 与世无争的帅哥 提交于 2019-11-28 04:38:42
Many .NET functions use XmlWriter to output/generate xml. Outputting to a file/string/memory is a very operation: XmlWriter xw = XmlWriter.Create(PutYourStreamFileWriterEtcHere); xw.WriteStartElement("root"); ... Sometimes , you need to manipulate the resulting Xml and would therefore like to load it into a XmlDocument or might need an XmlDocument for some other reason but you must generate the XML using an XmlWriter. For example, if you call a function in a 3rd party library that outputs to a XmlWriter only. One of the things you can do is write the xml to a string and then load it into your

Removing version from xml file

由 我只是一个虾纸丫 提交于 2019-11-28 02:51:49
问题 I am creating a Xml like format using XmlWriter . But in the output there is version information also. <?xml version="1.0" encoding="utf-8"?> I don't need this in my file. How can I do that?

Example: XmlWriter w; w.Settings = new XmlWriterSettings(); w.Settings.ConformanceLevel = ConformanceLevel.Fragment; w.Settings.OmitXmlDeclaration = true; 回答2: When creating your XmlWriter, pass through

Can we force XmlWriter to issue <my-tag></my-tag> rather than <my-tag/>?

由 你离开我真会死。 提交于 2019-11-28 00:40:29
By default, someXmlWriter.WriteElementString("my-tag", someString); produces <my-tag /> I looked around XmlWriterSettings class for possible options that would force the writer to produce <my-tag></my-tag> instead but didn't find anything. Is there a simple way of forcing the XmlWriter to issuing empty elements with "open tag, close tag" rather than with the short-hand form? Edit : Yes! I realize that with regards to XML validity the two notations are equivalent, valid and all... I'm however working with legacy code which parses such XML using Read(), i.e. at node level (!) and fumbles things

How do remove the BOM from an XML file that is being created? I have tried using the new UTF8Encoding(false) method, but it doesn't work. Here is the code I have: XmlDocument xmlDoc = new XmlDocument(); XmlTextWriter xmlWriter = new XmlTextWriter(filename, new UTF8Encoding(false)); xmlWriter.Formatting = Formatting.Indented; xmlWriter.WriteProcessingInstruction("xml", "version='1.0' encoding='UTF-8'"); xmlWriter.WriteStartElement("items"); xmlWriter.Close(); xmlDoc.Load(filename); XmlNode root = xmlDoc.DocumentElement; XmlElement item = xmlDoc.CreateElement("item"); root.AppendChild(item);

Serialize Entity Framework object with children to XML file

由 瘦欲@ 提交于 2019-11-27 16:52:43
问题 I'm querying data with parent/child result sets using Entity Framework and I want to export this data to an XML document. var agreement = storeops.Agreements.SingleOrDefault(a => a.AgreementNumber == AgreementTextBox.Text); XmlSerializer serializer = new XmlSerializer(agreement.GetType()); XmlWriter writer = XmlWriter.Create("Agreement.xml"); serializer.Serialize(writer, agreement); This works well except it only serializes the parent without including the related child records in the XML.

Create XML in Javascript

由 一笑奈何 提交于 2019-11-27 11:47:44
I'm wondering, is it possible to create an XML file with some data in Javascript? I have the data stored in variables. I've googled around a bit and it doesn't seem like it's talked about much. I thought i could use XMLWriter such as this: var XML = new XMLWriter(); XML.BeginNode ("testing"); XML.Node("testingOne"); XML.Node("TestingTwo"); XML.Node("TestingThree"); XML.EndNode(); as stated in this tutorial: EHow Tutorial However, when i execute this code i get the following error: ReferenceError: XMLWriter is not defined Any ideas on how i can get started with this? Thanks in advance!
