Differentiate between validating and non validating parser

For example, the tree structure of the "bookstore.xml" is as follows: An XML document comprises of the following basic units: to XML parser or an application program that uses the XML document.PI can be used for inserting non-XML statements, such as scripts, into the document, to be passed to an application for processing., if its structure meets the XML specification, i.e., it is syntactically correct.A well-formed XML document exhibits a tree-like structure, and can be processed by an XML processor.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.

Please note that the information in here is based upon the current spec for (X)HTML5.

Although HTML and XHTML appear to have similarities in their syntax, they are significantly different in many ways. There is a community who find it valuable to be able to serve HTML5 documents which are also valid XML documents. It is the overlap language of documents which are both HTML5 documents and XML documents.

They may, for example, use XML tools to generate the document, and they and others may process the document using XML tools. Guidelines are listed below for how one can construct such a polyglot document which will work in either environment.

ANTLR 2 accepts three types of grammar specifications -- parsers, lexers, and tree-parsers (also called tree-walkers).

Because ANTLR 2 uses LL(k) analysis for all three grammar variants, the grammar specifications are similar, and the generated lexers and parsers behave similarly.

In the future, ANTLR will optimize for UNICODE character sets. The /** This method is called by Your Token() * when the lexer has * hit EOF condition. * This method is not called if EOF is reached * during syntactic predicate evaluation or during * evaluation of normal lexical rules, which * presumably would be an IOException. * * upon EOF() is called after the complete evaluation * of the previous token and only if your parser asks * for another token beyond that last non-EOF token.
