How to prevent xml escape sequence entities with Linq?

HI,

I have generated some xml using the linq method, however, some of the elements are generated using the &gt and < entities. I'd like those to be translated.

The way I created the xml was by feeding in a string like:

XElement xElm1=new XElement.Parse("<div id="123"> abc </div>");

XElement xElm2=new XElement("Stuff", new XElement(xElm1));

But what comes out is: <div id="123"> abc </div>

I know I can do a replace string, but shouldn't the XElement spit out the properly translated entities??

Thanks!

Hi PhrankBooth,

Instead of passing the string values into the XElement constructor, pass the strings into XElement.Parse() and pass that result into the constructor. Here is an example:

1XElement aElem = new XElement("HTML", 
2                new XElement("HEAD",  
3                    new XElement("Style",  
4                        new XAttribute("type", "text/css"), _Style), 
5                        new XElement("Script",  
6                            new XAttribute("type", "text/javascript"), _Script)), 
7                            new XElement("BODY", XElement.Parse(_Body1), XElement.Parse(_Body2))); 

Sincerely,

I'm not sure why you are having trouble. I was able to use the following code to get the result you are looking for:

1 var xml = "<div id='123'>abc</div>";
2 var xElement1 = XElement.Parse(xml, LoadOptions.None);
3 var xElement2 = new XElement("Stuff", new XElement(xElement1));

With this code I ended up with the following XML:

1 <Stuff>
2 <div id="123">abc</div>
3 </Stuff>

I hope that helps. If not, maybe you could paste a bit more code so I can better understand where you are having difficulties?

thanks for your reply. Sorry I was going from memory and the actual code is this:

        private const string _Style = ".hidden { display: none; }" +
                                                ".unhidden { display: block; }";

        private const string _Script = "function unhide(divID) {" +
                                    "var item = document.getElementById(divID);" +
                                    "if (item) {item.className=(item.className=='hidden')?'unhidden':'hidden';}}";

        private const string _Body1 = "<div id=\"col1\"><ul></ul></div>";
        private const string _Body2 = "<div id=\"col2\"></div>";

        XElement aElem = new XElement("HTML",
                                    new XElement("HEAD",
                                    new XElement("Style", new XAttribute("type", "text/css"), _Style),
                                    new XElement("Script", new XAttribute("type", "text/javascript"), _Script)),
                                new XElement("BODY", _Body1, _Body2));

This is what aElem contains, note the entities in the Body:
<HTML>
<HEAD>
    <Style type="text/css">.hidden { display: none; }.unhidden { display: block; }</Style>
    <Script type="text/javascript">function unhide(divID) {var item = document.getElementById(divID);if (item) {item.className=(item.className=='hidden')?'unhidden':'hidden';}}</Script>
</HEAD>
    <BODY><div id="col1"><ul></ul></div><div id="col2"></div></BODY>
</HTML>

I expect those to be translated but they aren't. What is wrong here?
