How to show XML document content in HTMLPlaceholder control? I have XML document content in my silverlight app's string variable. I want to feed it in to the HTMLPlaceholder control and see Browser showing XML document parsed just like browsers typically show XML documents parsed and colored.

Thank you,
Andrew

Hello andrew rekvils,

Html placeholder will show the XML file the way the browser is displaying it. It do not have any functionality to deal with XML, other than that. Just point the SourceUrl property to the XML file.

My XML Document is not an external file or server resource that can be reached through Source Url property. My XML document is a string in my Silverlight application memory. I don't think SourceUrl property will help in this case. What can help then, if anything?

Thank you,
Andrew

Hi andrew rekvils,

You can parse the XML and convert it to HTML and then to pass it to the HtmlPlaceholder. See here how to display html string with the HtmlPlaceholder in Silverlight:

Unfortunately it will not be the same as if I had SourceUrl initialized with the path to valid XML file. In the later case HtmlPlaceholder uses underlying browser  to display XML content and that automatically creates colors indents, etc.. Also XML document in this case is "interactive" because its XML elements and nodes can be collapsed/expanded (this what IE and some other browsers do with external XML documents by default). By using my own custom formatting of XML string as HTML document I will not get this "interactivity".

Why wouldn't  you had HTMLPlaceholder property like Content-Type that by default is text/html and if it is text/xml it will interpret HtmlSource value as XML but not HTML and act on it accordingly. At the end of the day all we need is to let underlying browser to act on XML document the way it already can, we just need this functionality to be exposed through HTMLPlaceholder control.

Thanks,
Andrew

Hi andrew rekvils,

Basically we are using an iframe for external content and we dont have the option to change the content type.

Another option for you which will not require the parsing would be to save the XML content by using a service on the server, and then to direct the HtmlPlaceholder to the saved url ( e.g. to the XML file). This is not very good from performance point of view, but it all depends from your application requirements.
