Insert XElement into value of another XElement

Question

I have an XDocument object which contains XHTML and I am looking to add ABBR elements into the string. I have a List that I am looping through to look for values which need to be wrapped in ABBR elements.

Lets say I have an XElement which contains XHTML like so:

<p>Some text will go here</p>

I need to adjust the value of the XElement to look like this:

<p>Some text <abbr title="Will Description">will</abbr> go here</p>

How do I do this?

UPDATE:

I am wrapping the value "will" with the HTML element ABBR.

This is what I have so far:

        // Loop through them
        foreach (XElement xhtmlElement in allElements)
        {
            // Don't process this element if it has child elements as they
            // will also be processed through here.
            if (!xhtmlElement.Elements().Any())
            {
                string innerText = GetInnerText(xhtmlElement);

                foreach (var abbrItem in AbbreviationItems)
                {
                    if (innerText.ToLower().Contains(abbrItem.Description.ToLower()))
                    {
                        var abbrElement = new XElement("abbr", 
                            new XAttribute("title", abbrItem.Abbreviation),
                            abbrItem.Description);

                        innerText = Regex.Replace(innerText, abbrItem.Description, abbrElement.ToString(),
                                                  RegexOptions.IgnoreCase);

                        xhtmlElement.Value = innerText;
                    }
                }
            }
        }

The problem with this approach is that when I set the XElement Value property, it is encoding the XML tags (correctly treating it as a string rather than XML).

There's not enough information here. Why is "will" wrapped? What have you tried so far? — dav_i, Mar 13 '15 at 14:15
How much do you care about preserving the exact whitespace between words etc? — Jon Skeet, Mar 13 '15 at 14:18
There are several parts to this question: (1) Given a string, find known abbreviations within it. (2) Given an abbreviation, find its description. (3) Given an XElement containing text, replace a portion of the text with an XElement. Which part do you need help with? — Michael Liu, Mar 13 '15 at 14:22

If innerText contains the right XML you can try the following:

xhtmlElement.Value = XElement.Parse(innerText);

instead of

xhtmlElement.Value = innerText;

you can :

change the element value first to string,
edit and replace the previous element with the xmltag,
and then replace old value with the new value.

this might what you're looking for:

var element = new XElement("div");
var xml = "<p>Some text will go here</p>";
element.Add(XElement.Parse(xml));

//Element to replace/rewrite
XElement p = element.Element("p");
var value = p.ToString();
var newValue = value.Replace("will", "<abbr title='Will Description'>will</abbr>");
p.ReplaceWith(XElement.Parse(newValue));
