Yes it is. the xhtml 1.0 to be precise!
XML has no rules like html in regards to tags and naming tags, you write your own xml tags.
There was no XML in HTML 4, and you can only add XML to HTML 5 if you reset the content MIME type. XML hasn't changed. But XML is a language used to define other languages. XML was used to define the standards for XHTML 1.0, the successor to HTML 4. The rules of XML apply in XHTML, because the language is based off of XML. These rules are not, in any way, part of HTML 4. HTML 5 is not, by default, an XML based language. But there is a version that allows one to use the XML (or XHTML) style serialization. If you do this, however, you have to deliver the document using an XML MIME type, like application/html+xml. (Normally, this involves messing with the server a bit.) See the related link for HTML 5 Doctor's take on XML serialization in HTML 5, as well as some other, useful links.
As a programmer, processing pure XML is easier that HTML. This is because XML follows a very strict set of standards. HTML (such as HTML 4 or 5) does not. For instance, all XML tags close, either by a closing pair, or a "self-closing" tag. e.g.: <tag></tag> Or <tag /> Whereas HTML tags such as line-break and image don't follow the same pattern. <img> <br> By adhere to stricter rules, XML is easier for me to parse.
an xml value can be anything, its up to as xml is not a semantic language like html.
XML is more strict. For HTML, doing <b><i></b></i> wouldn't matter. That would be invalid XML. Also, XML has no set tags. It's for storing and retrieving set data, that can be used with JavaScript code.

You mean the file extension, right? HTML: .html or .htm XML: .xml
No. XML is a meta-language used to create other languages. XML was used to create XHTML, but neither is truly a subset or superset of the other. Think of XML as a set of rules that make the creation of languages simpler, rather than a language itself.It's also important to note that HTML 4 and HTML5 do notcomply with the XML rules.

xml can be written straight into html code and vice versa using the correct syntax, ie your html in here and your xml in here
No. XML is a meta-language. Rather than thinking of XML as a language, think of it as a way to build languages. It's a set of rules programmers can use to create their own languages. HTML is an SGML based markup language. It doesn't comply with the strict rules set forth by XML. Instead, it relies on a long history of doing things a certain way depending on context. XHTML was a revisioning of HTML as an XML compliant language. Essentially, it adjusted HTML so that it didn't break the XML rules. XHTML has now been replaced by the HTML 5 draft (which is at this point a de facto standard.) XHTML 2.0 has not been successful, and the Working Group hasn't moved on it in years.
XML is different from HTML in many ways. XML can be used mainly for mobile designing while HTML for web designing.
XML (eXtensible Markup Language) is a set of rules for encoding documents. The rules could describe anything from the rules of HTML to various file formats. WSDL (Web Services Description Language) provides a model for describing web services. WSDL uses the XML to specify its rules.
XML probably will not replace HTML. XML is a language to define categories of data. HTML is a language to define format.
XML (eXtensible Markup Language) is a set of rules for encoding documents. For example, XML can be used to define the rules of a particular file format such as HTML. It is not a programming language. C is a general purpose programming language which is used to write software.
HTML and XML both are markup languages. These languages use tags for functionality.
