System.Xml.Document : How to write special characters in an xml file ?

Question

Hello I have a little problem when saving my xml file. I use an instance of System.Xml.Document. I load an xml document file and edit this file with an application then when I save it (doc.save(file.xml) ) I would like also the whitespaces being saved. Example: It saves correctly the whitespaces but when I read it again the whitespaces are trimmed! To prevent that I would like to replace whitespaces by : &#32; but on saving the xml writer encodes this sequence into : &#32; and therefore it is not interpreted as a whitespace anymore... :(( Any help would be really appreciated thanks in advance!

Have you properly set the XmlDocument.PreserveWhitespace Property of your XmlDocument instance? Also Instead of using the &#32; decimal (base 10) entity try using the (base 16) UniCode entity as in &#x0020;
