Next, we will introduce Dom parsing in this chapter, Because Dom is a lot of parser used in J2EE. The parsing method here is the same as that of J2EE, the specific style is the same as the style in the following article.

Reading and setting the XML configuration file is the most common operation, using several C + + XML parsers, the personal sense of tinyxml is most comfortable to use, because its API interface and Java is very similar, object-oriented very good.TinyXML is an open source analytic library of parsing XML that can be used
Source code analysis of self-made XML Parser
First, let's determine the requirements:
(1) We want it to parse the XML string into a JSON object.
(2) At least compatible with Firefox and IE.
(3) This tool class should be a singleton.
Code:
/**
* Parse XML into a JSON object

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
: Ease of use and intuitive operation for Java developers. It is also committed to becoming a more complete solution than JDOM , achieving the goal of essentially addressing all java/xml issues. When this goal is completed, it is less stressed than JDOM to prevent incorrect application behavior. Dom4j is a very, very good
In the process of parsing XML files, it is found that the API documentation does not provide detailed description of parsing events, which brings a lot of troubles to parsing XML files, today we have a demo of Event Type Analysis to share with you.

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
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:

Recently do embedded development, the board needs to have the function of parsing XML, I will go to the Internet to find open source to use. The result is either C + + or super complex. Like Libxml, I count the next parse a 40 KB of XML files, incredibly dynamic application memory 100 times, for no MMU function of the ARM7, it is not a blessing to digest.
So, I can only write one to use.
I wrote this
XML is a common data transmission method. Therefore, during development, we will encounter parsing XML files. This article describes how to use the SAM parser to parse XML files.
The file format to be parsed is as follows:
