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: trea
An XML parser can read, update, create, and manipulate an XML document.

Tree-based Parser: This parser converts an XML document into a tree structure. It analyzes the entire document and provides APIs to access tree elements, such as the Document Object Model (DOM ).

First, the basic introduction
There are many ways to parse XML, including sax and Dom, and it is highly recommended in Android to parse XML in Xmlpull mode. Xmlpull not only can be used on Android as well as Javase, but in javase environments it is necessary to get the Xmlpull-dependent class library, Kxml2-2.3.0.jar,xmlpull_1_1_3_4c.jar.

The Java SAX Parser parses xml configuration files.
Recently, Tl asked me to do the technical accumulation of the company's projects. Today, let me finish parsing the xml configuration file with the SAX Parser. I have been working on a. Net project. Recently, I just transferred it to the Java group. I think. Is TL wait
models, such as SAX.

The advantages of this kind of processing are very similar to the advantages of streaming media. Analysis can begin immediately, rather than wait for all data to be processed. Also, because an application checks data only when it reads data, it does not need to store the data in memory. This is a great advantage for large documents. In fact, an application doesn't even have to parse the entire document; it can stop parsing when a condition is satisfied. In general, SA

In addition, because the application only checks data when reading data, it does not need to store the data in the memory. This is a huge advantage for large documents. In fact, the application does not even have to parse the entire document; it can stop parsing when a condition is met. In general, SAX is much faster than its replacement DOM.

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 l

Previously, when the project was published, every time you use the XML file in Windows with Notepad to save the run, you will always report an error:
XML Parser Error on line 1: content is not allowed in the preface.

Solve the Problem of XML-Parser in Linux-Linux general technology-Linux technology and application information. The following is a detailed description. If "yum-y install pidgin" is used to install pidgin, the installation is basically smooth as long as there is no network problem. However, I prefer to install pidgin with the source code package to pursue my personality. /configure has an error: "configure:
In recent articles on XML and MSXML DOM parsers in Kenn Scribner, only some of the features of the parser are described. These articles describe XML as a technology, but do not introduce the XML parser itself. Now, Kenn will go back to the MSXML
Next, let's take a look at the SAX Parser. In fact, it's similar to the PULL parser. In fact, it's enough to learn and master an XML parser to complete the project, of course, it is not a bad thing to learn more. What do you mean? Come on! Let's take the data of Tang Miao's migration as an example.

Recently, I encountered an XML parsing problem in the project. We used the DOM parser that comes with android to parse XML, but found a problem with android, that is, on SDK 2.3, strings such as

Sometimes, we need to generate an XML file. There are many ways to generate an XML file. For example, we can use only one stringbuilder to group XML content and then write the content into the file; you can also use the pull parser to generate xml files by using Dom APIs. We
