Adding XML string to XElement

Question

Hi I need to create an XElement from a string, which can be xml or plain string.

This code

    var doc = new XDocument(
        new XElement("results", "<result>...</result>")
    );

produces this

<results>&lt;result&gt;&lt;/result&gt;</results>

But if the string is XML, then I need proper XMl

<results><result>...</result></results>

Any ideas other than XElement.Parse() because it will throw exception if it is plain text?

You could test if the string is xml. E.g. it contains < and > if so use the parser, if not do something else (hard to tell what you wan't when its not XML) — CodeTower

I was going to say this is a duplicate of stackoverflow.com/questions/1414561/…, but the key point is "other than XElement.Parse()", which is actually my question too, if not for the same reasons — drzaus

See my answer on Is there an XElement equivalent to XmlWriter.WriteRaw?

Essentially, replace a placeholder for the content only if you know it's already valid XML.

var d = new XElement(root, XML_PLACEHOLDER);
var s = d.ToString().Replace(XML_PLACEHOLDER, child);

This method may also be faster.

I don't know if there is other way around and it also doesn't look as a best way but you can achieve it like this:

object resultContent;

if (condition)
{
    //if content is XmlElement
    resultContent = new XElement("result", "....");
}
else
{
    resultContent = "Text";
}

XDocument xDoc = new XDocument(new XElement("results", resultContent));

How about doing this:

XElement.Parse(String.Format("<Results>{0}</Results>",possibleXMLString));

... and before someone objects to this employing .Parse() method, which is mentioned by OP, please note that this is not the usage that was mentioned.
