Best way to get InnerXml of an XElement?-第2页回答

What's the best way to get the contents of the mixed body element in the code below? The element might contain either XHTML or text, but I just want its contents in string form. The XmlElement type has the InnerXml property which is exactly what I'm after.

The code as written almost does what I want, but includes the surrounding <body>...</body> element, which I don't want.

XDocument doc = XDocument.Load(new StreamReader(s));
var templates = from t in doc.Descendants("template")
                where t.Attribute("name").Value == templateName
                select new
                {
                   Subject = t.Element("subject").Value,
                   Body = t.Element("body").ToString()
                };

I think this is a much better method (in VB, shouldn't be hard to translate):

Given an XElement x:

Dim xReader = x.CreateReader
xReader.MoveToContent
xReader.ReadInnerXml

public static string InnerXml(this XElement xElement)
{
    //remove start tag
    string innerXml = xElement.ToString().Trim().Replace(string.Format("<{0}>", xElement.Name), "");
    ////remove end tag
    innerXml = innerXml.Trim().Replace(string.Format("</{0}>", xElement.Name), "");
    return innerXml.Trim();
}

Is it possible to use the System.Xml namespace objects to get the job done here instead of using LINQ? As you already mentioned, XmlNode.InnerXml is exactly what you need.

@Greg: It appears you've edited your answer to be a completely different answer. To which my answer is yes, I could do this using System.Xml but was hoping to get my feet wet with LINQ to XML.

I'll leave my original reply below in case anyone else wonders why I can't just use the XElement's .Value property to get what I need:

@Greg: The Value property concatenates all the text contents of any child nodes. So if the body element contains only text it works, but if it contains XHTML I get all the text concatenated together but none of the tags.

doc.ToString() or doc.ToString(SaveOptions) does the work. See http://msdn.microsoft.com/en-us/library/system.xml.linq.xelement.tostring(v=vs.110).aspx

var innerXmlAsText= XElement.Parse(xmlContent)
                    .Descendants()
                    .Where(n => n.Name.LocalName == "template")
                    .Elements()
                    .Single()
                    .ToString();

Will do the job for you
