XML sitemaps can be found for a specific website by adding sitemap.xml to the end of the web address. This is Google's preferred format for XML sitemaps.
You mean the file extension, right? HTML: .html or .htm XML: .xml
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
XML is different from HTML in many ways. XML can be used mainly for mobile designing while HTML for web designing.
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.
XML probably will not replace HTML. XML is a language to define categories of data. HTML is a language to define format.
basikly xhtml is a mics of html and xml. the difference in html and xhtml is that xhtml is a more strict on the syntax and defined as a xml document. xml is a self defined language... in short it is a strikter html in xml format...
HTML and XML both are markup languages. These languages use tags for functionality.
an xml value can be anything, its up to as xml is not a semantic language like html.
A site map is a list of all of a website's pages. An XML site map is for search engine use, and is usually placed in the root directory of your website. An HTML site map is the user version to help your website's visitor navigation.
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.
XML Sitemap For search engines Helps Google crawl & index pages File format: .xml Not visible to users Example: /sitemap.xml HTML Sitemap For users Shows website page list Improves navigation Page format: .html Visible on website Difference (Quick) XML → Bots HTML → Humans
