At this time I learned to be good, no longer everything from the wheel to build J, started when originally wanted to use Yacc/lex as the bottom compiler, but because the entire application is pure Java, based on portability considerations. And because I don't want to deal with a whole bunch of yacc/lex generated by the principle of pushing my own initiative, I've chosen an o

There are two basic types of XML parsers: Tree-based parser: This parser transforms an XML document into a tree structure. It parses the entire document and provides an API to access the elements of the tree, such as the Document Object Model (DOM). Event-based parser: treats an XML document as a series of events. When a specific event occurs, the

First, use the Pull parser to read XML files In addition to using SAX or DOM to parse XML files, you can also use the Android built-in pull parser to parse XML files. The pull parser is an Open-source Java project that can be used for both Android and Java EE. If you need to put the jar file into the classpath with Java EE, because Android is already integrated

Lucene provides a rich set of APIs to assemble and customize the queries you need, and you can use the powerful query syntax parsing provided by query parser to construct the query you want. This article describes the query syntax for Lucene in detail. Parse a query string into Lucene's query through the Java parser. Before you choose to use Query parser, conside

The view parser provided by Spring MVC uses Viewresolver for view parsing to implement a rendering model in the browser. Viewresolver can parse multiple views such as JSPs, velocity templates, freemarker templates, and XSLT.The two most important interfaces of the spring processing view are viewresolver and view. The Viewresolver interface provides a mapping between the view name and the true view, while the view interface processes the request to ren

The XML Parser can read, update, create, and operate an XML document. Use XML Parser Microsoft's XML parser is bundled with ie5.0 + browser. Once ie5.0 is installed, the XML parser is obtained. In addition to being called by the browser, this browser can also be called in scripts or programs. This

Recently reading the prestigious "Dragon book", read the section of the grammatical analysis, about the compiler of the grammatical Analysis section, Dragon book mainly on the top-down grammar analysis and bottom-up analysis of two types of parsing methods, top-down grammar analysis mainly corresponds to ll grammar, and the bottom-up of the grammatical analysis mainly corresponds to the LR grammar, The details of the grammar are not discussed here. This paper mainly discusses the advantages and

Use PHP-Parser to generate AST abstract syntax tree 0 and preface Recently, the project process has gradually become clear, but many key technologies are not mastered, and they can only be explored step by step. Because static code analysis based on data stream analysis is required, front-end work such as lexical analysis and syntax analysis is essential. Yacc and Lex will not be considered any more. I checked the information for one day and found

Because the use of the official website is very inconvenient, the parameters are not detailed description, also can not find very good information.

The pull parser is an open-source Java project that can be used for both Android and javaee. If it is used in javaee, you need to put its JAR file into the class path. Because android has already been integrated into the pull parser, no JAR file needs to be added. XML files used by the Android system are parsed using the pull parser. The Running Method of the pul
