J2ME Kxml Example
This is the simple kxml application, In this application we'll show you how to work with
kxml parser and how to parse the xml file in the midlet .
In this section we take the following steps:
- We
create an employee.xml file, in which we have four tags that is : name,
city, state and designation.
- We use the XmlParser in our MIDlet to
access the value of xml file and print on the j2me console.
- We manipulates the DOM to parse the xml file.
Manipulating
the DOM is a simple way of interacting with XML, where the entire XML tree is
parsed into a node structure. The XML tree resides in memory and you can traverse the
tree programmatically.
The Entire Application is as follows:
