An is the software that sits between the application and the XML documents to shield the application developer from the intricacies of the XML syntax.
The parser reads a raw XML document, ensures that is well-formed, and may validate the document against a DTD or schema.
Worse still, many of the markup tags are dealing with the appearance of the document (e.g., XML declaration XML comment Root element start-tag (one and only one root) Child element start-tag (with an attribute in name="value" pair) (proper nesting of child elements) Child element end-tag Second child element start-tag Second child element end-tag Third child element start-tag Third child element end-tag Root element end-tag pairs.
Different style sheets can be applied to the same XML document for display on different platform or devices (desktop browser, PDA, mobile phone).
W3C has developed two style sheet standards, that can be used with XML documents: XSL Transformation (XSLT) is a text-based transformation process that merges a textual XML source document with a XSL style sheet to procedure a target document. The root element The matching criteria is specified using XPath (XML Path Language).
It specifies a set of constraints and establishes the trees that are acceptable in an XML document.
A DTD can be declared inside an XML document (i.e., if it meets the constraints spelled out in a DTD (Document Type Definition) or an XML Schema, imposed by a specific application.
XML focus on the content of the document and gives no clue on the appearance or presentation.
