I have textboxes that i save the text to an xml file.The first textbox goes into the element name and the second goes into the value so I want to be able to use any chars in these textboxes but i get errors saying The character ' ' hexadecimal value 0x20 cannot be included in a name.the one textbox is used for the namespace and the other for the value.I need to allow chars in the name.I am using XDocument and not XmlDocument

What I have tried:

i have looked on Google but all i find is how to remove chars not how to allow them.I tried it the way it is but if i enter chars then it throws exceptions.

You're probably talking about a CDATA section. They can be used to store any text information you want without having to worry about escaping characters.

Google: "XML CDATA"[^]

Does CDATA allow for spaces ??

What happened when you tried it?

You can put anything you want inside the CDATA section, the sole exception to that being the character sequence ]]>.

well i tried but it always gives me the error "names cannot start with<"

Codingnow20 14-Aug-18 13:59pm

basically what i want to do is to enter any character into a textbox that becomes the element name and the other textbox will be its value.Maybe its not possible but i sure hope it is

OK. I can't see your code and what you're typing into the textboxes so I can't tell you what's going wrong.

XDocument xdoc = XDocument.Load("SavedData.xml");
xdoc.Add(new XElement(new XCData(textbox1.text).ToString(),textbox2.text));

You've got the parameters for the new XElement backwards. The name you want to call the element comes first and the value, your new XCData object, comes second.

    xdoc.Add(New XElement(textbox2.text, new XCData(textbox1.text)));

the name i want to call the element comes from textbox1 say iI type John Doe in the textbox1 it says that names can't include spaces.

How am I supposed to know that when you're using the default names of the textbox's?

In that case, swap the textbox names in that line of code!

Better yet, give meaningful names to all of your controls!

that is what i am using to write to the xml but it always says names cant start with '<'
