Serialize object to XmlDocument

阅读更多关于 Serialize object to XmlDocument

In order to return useful information in SoapException.Detail for an asmx web service, I took an idea from WCF and created a fault class to contain said useful information. That fault object is then serialised to the required XmlNode of a thrown SoapException . I'm wondering whether I have the best code to create the XmlDocument - here is my take on it: var xmlDocument = new XmlDocument(); var serializer = new XmlSerializer(typeof(T)); using (var stream = new MemoryStream()) { serializer.Serialize(stream, theObjectContainingUsefulInformation); stream.Flush(); stream.Seek(0, SeekOrigin.Begin);

问题 I'm trying to read weather data from XML in a URL.

Decode CDATA section in C#

阅读更多关于 Decode CDATA section in C#

问题 I have a bit of XML as follows: <section> <description> <![CDATA[ This is a "description" that I have formatted ]]> </description> </section> I'm accessing it using curXmlNode.SelectSingleNode("description").InnerText but the value returns \r\n This is a "description"\r\n that I have formatted instead of This is a "description" that I have formatted. Is there a simple way to get that sort of output from a CDATA section? Leaving the actual CDATA tag out seems to have it return the same way.

Reading XML with an “&” into C# XMLDocument Object

阅读更多关于 Reading XML with an “&” into C# XMLDocument Object

I have inherited a poorly written web application that seems to have errors when it tries to read in an xml document stored in the database that has an "&" in it. For example there will be a tag with the contents: "Prepaid & Charge". Is there some secret simple thing to do to have it not get an error parsing that character, or am I missing something obvious? EDIT: Are there any other characters that will cause this same type of parser error for not being well formed? The problem is that the xml is not well-formed. Properly generated xml would list that data like this: Prepaid & Charge I've had

Creating an XML document using namespaces in Java

阅读更多关于 Creating an XML document using namespaces in Java

I am looking for example Java code that can construct an XML document that uses namespaces. I cannot seem to find anything using my normal favourite tool so was hoping someone may be able to help me out. I am not sure, what you trying to do, but I use jdom for most of my xml-issues and it supports namespaces (of course). The code: Document doc = new Document(); Namespace sNS = Namespace.getNamespace("someNS", "someNamespace"); Element element = new Element("SomeElement", sNS); element.setAttribute("someKey", "someValue", Namespace.getNamespace("someONS", "someOtherNamespace")); Element

How can I stop empty XML elements self-closing using XmlDocument in C#?

阅读更多关于 How can I stop empty XML elements self-closing using XmlDocument in C#?

问题 Before I get jumped on by people saying the XML parser shouldn’t care if the elements are empty or self-closed, there is a reason why I can’t allow self-closed XML elements. The reason is that I’m actually working with SGML not XML and the SGML DTD I’m working with is very strict and doesn't allow it. What I have is several thousand SGML files which I’ve needed to run XSLT on. I’ve therefore had to convert the SGML to XML temporarily in order to apply the XSLT. I’ve then written a method that
