Contenthandler is actually an interface. when processing a specific XML file, you need to create a contenthandler class for it to process specific events. It can be said that, this is actually the core of processing XML files by sax. Let's take a look at some of the
and easier to use than HTML because of its better hypertext link capabilities.
3) XML provides more and better mechanisms to facilitate browser information performance and optimize performance.
4) XML removes the complexity of SGML, so it is easy to write an application that processes XML.
5) information is easy to store and can be reused.

Java 6.0 has many aspects of the new features that XML supports. For example, Stax, Java Architecture for Xml-web Services (JAX-WS) 2.0, XML-bound APIs (JAXB) 2.0, XML digital signature APIs, and even sql:2003 '
In normal work, it is inevitable that XML will be used as the data storage format. Which of the following solutions is the most suitable for us? In this article, I made an incomplete evaluation of the four mainstream solutions, and only tested the XML traversal, because XML traversal is the most commonly used at work (at least I think ).

Generally, when we mention XML, most problems will be resolved in XML and XML structures. In this field of technology, W3C proposed Dom and sax specifications to parse data. Sun provides Java XML pack, while Apache releases xerces and xalan. However, there is almost no focus

What is Jdom?
Jdom is an open-source project that uses java-only technology to parse, generate, serialize, and operate XML documents based on the tree structure. It is a direct java Programming Serv
Xml| programming from the date of the birth of XML, it has been the industry's focus on one of the topics. After several years of development, XML technology is becoming more and more mature, now more and more applications are based on XML development.

Introduction: This paper briefly describes the concept and internal logic structure of DOM, and gives the Java implementation process
XML, as a common structured language in the world, is becoming more and more popular, with various development platforms (such as Microsoft studio series, Oracle series, and inprise Borland series) XML development is also supported as one of the promotion slogans. Because XML was introduced earlier in e-government development, I have tasted a lot of sweetness and
XML language (Extensible Markup Language): Describes a series of relational data, allowing custom tags, which are commonly used as software configuration files to describe the relationship between program modules.
XML syntax: Document declarations, elements, annotations (data area, special characters, processing instructions (processing instruction))

In the previous section of this series, I demonstrated how to remove an XML document and convert it to a Java representation. The key to this transformation is the XML schema that the XML document conforms to. The pattern ensures not only mandatory constraints. It also allows the use of Schemamapper to generate

Because of its traversal capabilities, DOM parsers are often used in services where XML documents require frequent changes.The SAX parser uses an event-based model that can trigger a sequence of events when parsing an XML document, and when a given tag is found, it can activate a callback
Jdom, which does not implement JAXP, but is popular because of its simplicity and becomes the API officially recommended by JCP. It is also a tree-like structural representation of XML, which is much simpler to use than the DOM standard of the consortium. The latest version of Jdom has already started using the JAXP API internally, it will try to invoke the Jaxp API as much as possible, and if not, use its own default
excellent performance, powerful functionality, and extreme ease of use, is also an open source software. Now you can see that more and more Java software are usingDom4j is used to read and write XML. It is particularly worth mentioning that Sun's jaxm is also using dom4j.
