I'm attempting to create a test framework in c# to automate some of our API tests. Relatively new to this area so have come across an issue I can't solve. My XML payload is as below:

    <Item IsKit="false">

When I attempt to execute the above(using RestSharp) I get the below error: "System.Xml.XmlException: 'The ' ' character, hexadecimal value 0x20, cannot be included in a name.'"

The offending line of code is

        <Item IsKit="false">

...where the code in c# I have written is as below

        XElement items = new XElement("Items");
        items.Add(new XElement("Item IsKit =\"false\""

I believe the issue is because there are spaces between the words 'Item' and 'IsKit'....my question is how I would get around this in order for this element to be added to my test code?

  • Your Items tag is not closed and might be causing the issue. Commented Oct 3, 2018 at 11:45
  • sorry I didn't put the closing tag in the code example above. thanks for pointing that out, however I still have the original issue Commented Oct 3, 2018 at 12:01

you are trying to make an element called 'Item IsKit =\"false\"'

it looks like you actually want to create an Element called Item with an attribute called IsKit.

Try this:

new XElement("Item",new XAttribute("IsKit", "False"))
