XML Parsing - 1


Lets start with the structure of XML first.

XML is a way of storing data..

sample xml file:

<?xml version="1.0" encoding="UTF-8"?>
<person>
<name>Richa</name>
<age>100</age>
<lastname>Vaidya</lastname>
<address>India</address>
</person>


the first line gives the version of the xml i.e 1.0

the next line person is the root all the contents of the xml are a part of the root i.e. person

the later lines.. these are the elements of the root.

So now we have the data, how do we use it in a java program.
Read it line by line?

No... We have been provided with two excellent parsers : DOMParser and  SAXParser.

Difference between DOMParser and SAXParser., DOM reads the complete xml element, so you have the complete file in the memory and you can access the elements of the DOM root at you wish. SAX parser reads the file line by line.

DOM parser has a greater memory print than SAX parser.

Use of DOM or SAX should be dependent on the need of the application.

Writing your own ejabberd Module

By -
Coming soon: What is ejabberd? What is erlang? Installation details. I will start with writing the ejabberd module first. Once you have done all the installations: sudo make sudo make install sudo ejabberdctl start sudo ejabberdctl stop You can check the status using: sudo ejabberdctl status You can locate logs at: (With default installation) /var/log/ejabberd All config related changes will be mainly done at: /etc/ejabberd/ejabberd.yml You will need a basic understanding of erlang. You can take a short crash course at: http://www.erlang.org/course/course.html This is a good reference. Go to your ejabberd-15.07/src directory. This is where you will write the hook for your ejabberd server. Create a file, say mod_changeBody.erl. Your module name and file name should be same. Add the following basic contents into your erl file: -module(mod_changeBody). -behavior(gen_mod). -include("ejabberd.hrl"). -include("logger.hrl"). -expo

Conditional Flow - Spring Batch Part 6

By -
Jump to Conditional Flow using Custom Status There can be muliple scenario where you want your jobs to proceed depending on the outcome of your steps. For example, in case of our Corporate gifts shop, in case the automatic packaging of the gifts fails, we want some manual intervention to be done i.e. somebody should manually package the item.  IF-ELSE IF loop for packaging:     if packageStep fails                              then manualPackageStep                         else if packageStep executes successfully                              then sendOutForDelivery Entire code available at git repo:   https://github.com/ricsr/spring-batch-demo/tree/exercise_06 Using SpringBatch you can achieve it as follows: Create you manualPackageStep, which is very similar to your packageStep, except that it does the packaging manually. @Bean public Step manualPackageStep () { return this . stepBuilderFactory .get( "manualPackageStep" ).tasklet( new Tasklet() { @Override pu
