Recently, I have been studying crawler-related things and used HTML Parser. I don't want to talk about anything else. Most of the content on the Internet is my experience with custom tags.
1. Brief Introduction to HTML
In the words of Baidu Encyclopedia:
Htmlparser is a pure library written in Java for HTML Parsing. It does not depend on other Java library files and is mainly used for transformation orExtract HTML. It can parse HTML at a high speed w
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
An XML parser can read, update, create, and manipulate an XML document.

0. Preface
The process of recent projects is becoming clearer, but many of the key technologies are not mastered and can only be explored step-by-step.
Because of the static code analysis based on data flow analysis, the front-end work such as: lexical analysis, grammar analysis is essential. Yacc and Lex What no longer consider, check the information of the day, found two more suitable, one is the ANTLR under the Java, another is specialized do PHP ast generated php-

I. XML element structure routine
The first routine indent shows the start element structure in the document.
Example #1 display the XML element structure
II. XML tag ing routine
Example #1 map XML to HTML
This routine maps XML tags directly to HTML tags. Elements not found in map_array are ignored. Of course, this
This is an independently implemented SGF go chess and music file parser by liigo. This article introduces its implementation details. There is no doubt that a complete open-source SGF parser can be found on the network. I Don't directly use them, nor refer to their implementation code, but implement them independently, there is a reason, because I want to reinvent the wheel myself and think it will help imp

Using PHP simple HTML DOM Parser parsing HTML tags using a PHP easy HTML DOM Parser parsing the HTML page, it feels good, it can create a DOM tree to facilitate you to parse the content inside the HTML. It's good to grab something. With an example, you also go to SourceForge to download the compressed package look inside the example: scraping data with PHP simple HTML DOM
Now ACM does not engage, a look at an article published time is February 13, really startled myself. Since the internship has begun, then engage in technology, but the algorithm can not break the study, the introduction of the algorithm and a lot of knowledge did not learn it well, since the assignment during the internship is to engage in a crawler, then I would like to say the Java HTML Parser specific analytic way it. First Network crawler general
first of all , introduce the core class of the next Htmlparser, Org.htmlparser.Parser class, this class actually completed the analysis of the HTML page. The main constructors are as follows:public Parser (); Public Parser (String Resource) throws Parserexception; Public Parser (String resource, parserfeedback feedback) throws parserexception; Public

In Android, the pull parser is used to generate XML files and read XML files.
In Android, the Pull parser 1 is used, and the running mode of the Pull parser is similar to that of the SAX Parser. It provides similar events, such as the start element and end element events. 2. Use p

I have been searching for a useful JavaScript Parser for Jscex. Previously I used Narcissus and wrote related articles. Unfortunately, Narcissus uses the extension of SpiderMonkey, so it is not implemented using ECMAScript 3 and cannot be used in IE 8 or other browsers. Currently, Jscex uses the earlier version of Narcissus in NarrativeJS, but I do not like the AST structure output. I also found some bugs in advanced functions, which may seem boring,

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 parser supports programming models unrelated to programming languages. it supports the following technologies:
