How to save XmlDocument with multiple indentation settings?

阅读更多关于 How to save XmlDocument with multiple indentation settings?

I need to save one XmlDocument to file with proper indentation (Formatting.Indented) but some nodes with their children have to be in one line (Formatting.None) . How to achieve that since XmlTextWriter accept setting for a whole document? Edit after @Ahmad Mageed's resposne: I didn't know that XmlTextWriter settings can be modified during writing. That's good news. Right now I'm saving xmlDocument (which is already filled with nodes, to be specific it is .xaml page) this way: XmlTextWriter writer = new XmlTextWriter(filePath, Encoding.UTF8); writer.Formatting = Formatting.Indented;

XmlDocument and slow schema processing

阅读更多关于 XmlDocument and slow schema processing

I have an xml template document that I need to load into an XmlDocument. eg myXMLDocument.Load(myXMLFile); However this is very slow as it loads in the dtd. I have tried both "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd" and a local copy of the dtd. Both take more or less the same time. If I turn of loading the dtd by setting the resolver to null (for example), I then get errors such as "Reference to undeclared entity 'nbsp'" if the document contains these. I need to use an XmlDocument as I need to manipulate the DOM before outputting the document. How can I get round these problems? You can

How make XMLDocument do not put spaces on self-closed tags?

阅读更多关于 How make XMLDocument do not put spaces on self-closed tags?

I have an XML well formatted without any spaces. It' must be like that. When I load it to XMLDocument to sign, the self-closing tags gets an extra white space and <cEAN/> becomes: <cEAN /> Once this document must be signed, it's impossible to remove the white space. The property PreserveWhiteSpace doesn't made any difference to the result. How can I change this behavior? There is no space before the closing "/" in the XmlDocument . XmlDocument is a data structure consisting of nodes. It is binary. It is not text. Any extra space you are seeing exists only when you serialize the document as

Why does System.Xml.XmlDocument.LoadXml method throw System.Net.WebException ? This is really mind boggling crazy, if MSDN was right, LoadXml should at most give me a System.Xml.XmlException . Yet I have weird exceptions like: The underlying connection was closed: The connection was closed unexpectedly. Dim document As New XmlDocument document.LoadXml("<!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""><x></x>") MsgBox(document.LastChild.Name) What on earth is causing the exception ? Edwin gave you the solution, and I'm
