Conversion of XML file in to HTML webpage or document. HTML is based on XML, but XML is not HTML. XML is a representation of data, HTML is a markup language. If you want XML to display like a webpage, add a CSS file to the XML and style it. There might be possible solution using XSLT Transformation to convert XML to HTML
Documents from Word exported in XML, can also be imported back to Word and saved in HTML format. But that does not work for just any XML.
