Incomplete Escaping Functionality??I am in an app that needs to write out an XML document for transmittal to an outside organization. All good and fine... I create the XmlDocument object, append all my nodes, and values etc etc... and it all works. Now I go to save the file... I tried two methods... MyXmlDocument.Save(filename) and My.Computer.FileSystem.WriteAllText(filename, MyXmlDoc.OuterXml, False) The problem comes in with XmlDocument.OuterXml. According to XML, there are 5 characters which need to be escaped... Ampersand, LessThan, GreaterThan, Apostrophe and DoubleQuote. XmlDocument.OuterXml, escapes only three of these ( & , < and > ). Apostrophe and DoubleQuote do not get escaped. This is a problem, because the third party we need to deal with *must* have them escaped, even inside of a Nodes InnerText. So I figured okay, I'll just escape them myself, but when I try to do that, it winds up escaping my Ampersand (for example in """ ), so that it winds up saving "&quot;". How in the world can I tell it that it needs to escape ALL FIVE CHARACTERS? Thanks in advance, - Arthur Dent.

If so, you need to escape them when you create the text node. John Arthur Dent wrote:

"The ampersand character (&) and the left angle bracket (<) MUST NOT appear in their literal form, except when used as markup delimiters, or within a comment, a processing instruction, or a CDATA section. If they are needed elsewhere, they MUST be escaped using either numeric character references or the strings "&" and "<" respectively. The right angle bracket (>) may be represented using the string ">", and MUST, for compatibility, be escaped using either ">" or a character reference when it appears in the string "]]>" in content, when that string is not marking the end of a CDATA section. To allow attribute values to contain both single and double quotes, the apostrophe or single-quote character (') may be represented as "'", and the double-quote character (") as """." So & and < MUST always be escaped, while >, ' and " only must be escaped under certain circumstances, otherwise they MAY be escaped. But actually you shouldn't care about XML syntax, XML takes care of it. -- Oleg Tkachenko [XML MVP, MCPD] http://blog.tkachenko.com | http://www.XmlLab.Net | http://www.XLinq.Net I have an XmlNode whose InnerText property contains DoubleQuote.
This causes problem with the 3rd party, because their software cannot handle the doublequote in the innertext. When I tried to manually escape it using """, the Xml parser escaped my "&" on me, and saved it to the file as "&quot;"... effectively making it impossible for me to manually escape the doublequote. Ultimately, I wound up adding the text inside of a CDATA section. This worked for the 3rd party. From looking around though, it looked online, like CDATA is a holdover, and not the recommended way of doing things.
