You need some sort of parser.
That is too difficult for "beginning", so I shall move you.

What kind of validation? Do you mean parsing XML documents against a DTD or XSD file?

For XSD validation it's actually not that hard. You first use SchemaFactory to create a Schema.
Next you create a DocumentBuilderFactory or SAXParserFactory, set the Schema and set validating on.
Next you use the DocumentBuilderFactory to create a DocumentBuilder, or the SAXParserFactory to create a SAXParser.
Finally, you use the DocumentBuilder or SAXParser to parse the XML document.

xhtml is infinitely "extensible", in essence, by the x itself so named. I suppose you don't mean you've your own custom module extending the base of it?... xhtml validation is no difference from validating any schema/DTD backed xml document and the outline of how to do it is already pointed out.

If you mean you are not yet very agile in doing validating xml, I would say you can use many validating service out there such as this or any other you might come across after by googling.

You can cut-and-paste the "string" for the purpose or you can use the variation of validating via a url...

So what's the problem exactly? Do you not know how to do XML validation? Or is that you know how to do that, but not if the XML is in a String?
 
I agree. Here's the link: http://aspose.com/file-tools
