xml stands for extensible markup language, its amarkup language that allows you to carry and display data across different platforms and systems.
Some programs require XML-structured data. But there are ways around that, so if you know that programs do not need XML-structured data, then no -- you do not need XML.
That depends on what you want to do, xml tools include; xml parsers xml validators xml editors xml schema editors xml code generators
there is no source code, xml is not a programming language, its a markup language for which you create your own tags, the basic xml syntax is <xml> to start an xml file, and </xml> to end the xml file.
it is the same way to create xml file by converting into txt you have to use the correct xml syntax ie <xml> this is to denote strat of xml file and this </xml> denotes end of xml file. You have to use the right xml code or your xml file wont be valid or well formed.
If you open the xml in most web browser it will state an error code denoting the type of malformation of the xml. you can use an xml tool like an xml editor to validate and correct your xml.
If you use an xml tool like liquid xml studio or any other xml tool you will be able to convert your xml into an xsd or dtd.
XML Schema is an XML-based alternative to DTD.An XML schema describes the structure of an XML document.The XML Schema language is also referred to as XML Schema Definition (XSD).An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself.
XML and WML both use the same markup / language. If you know XML, you know WML - and vice versa. However, XML is intentionally developed for computers, or other devices with larger screens. WML is developed for smaller-screened devices, such as PDA's and cell phones. Regardless, most devices, small or large screen'ed, now accept both formats of the XML language without complaining - but users may notice a difference in layout. On the technical side of things, WML standards branch off XML standards (which determine how things should be layed out on a screen or other display) - making the standards relatively different. WML is placed in WML-type documents ("file.wml"), as XML is placed in XML-type documents ("file.xml"). WML documents should have a Document Type Declaration pointing to an WML standard, as XML documents should have a Document Type Declaration pointing to an XML standard.
XML is a language used to store data. XSLT is a language which is used to transform XML into other XML.
Well-formed XML means that the XML is correct (it has only one root node, and all elements match an end element tag)Valid XML means that the XML can be validated to an XML Schema or DTD, and that all the tags in the XML are also in the Schema or DTD, and in the right place.
xml stands for extensible markeup language, xml is a meta language.
an xml value can be anything, its up to as xml is not a semantic language like html.
