as i see it

Background : Selenium is an open source tool for web application testing.
Selenium IDE is a Firefox plugin allows you to record tests in browser and run them from the browser or as a java test ( or any other languages ) using Selenium Remote Control libraries.
You can extend functionality of Selenium IDE by writing Event Handlers, Locator Builders, Command Builders, Custom Format all in JavaScript.
For more about that http://wiki.openqa.org/display/SIDE/Writing+extensions.

More on Locator Builders
Locator Builders decide how HTML elements in a page are identified.
eg id attribute is a default locator builder.
So while recording a test an html element attribute selenium using the id attribute to recognize the element you changed, clicked etc.

Writing a new locator builder

You can instruct selenium to use a custom attribute to identify the elements in your page. Default Locator builders can be found at chrome://selenium-ide/content/locatorBuilders.js

Here's the js code to add a location builder for an attribute myattr

LocatorBuilders.add('myattr', function(e) {
if (e.hasAttribute('myattr')) {
if (e.getAttribute("myattr")) {
return '//' + e.nodeName + '[@myattr=\'' +
e.getAttribute("myattr") + '\']';
}
}
return null;
});


Since there are plenty of existing location builders, you need to specify the order in which they are invoked. This is how its done

LocatorBuilders.order = ['myattr','id', 'link', 'name', 'dom:name',
'xpath:link','xpath:img', 'xpath:attributes', 'xpath:href',
'dom:index', 'xpath:position'];

Complete code: mylocator.js

LocatorBuilders.add('myattr', function(e) {
if (e.hasAttribute('myattr')) {
if (e.getAttribute("myattr")) {
return '//' + e.nodeName + '[@myattr=\'' +
e.getAttribute("myattr") + '\']';
}
}
return null;
});

LocatorBuilders.order = ['myattr','id', 'link', 'name', 'dom:name',
'xpath:link','xpath:img', 'xpath:attributes', 'xpath:href',
'dom:index', 'xpath:position'];

Steps to add the extension code to selenium IDE

• Write locator code in a new .js file

• Specify the path in "Selenium IDE extensions" field in Selenium IDE > Options and restart selenium IDE

Heres a simple code snippet in java for writing an xml document created
to an xml file.
Seems quite a common task but had to google quite a bit to get it right ....



Document doc = null; // load your DOM into this document object

TransformerFactory transfactory = TransformerFactory.newInstance();

Transformer transformer = transfactory.newTransformer();

StringWriter writer = new StringWriter();
StreamResult destination = new StreamResult(writer);
DOMSource source = new DOMSource(doc);

transformer.transform(source, destination);

String xmlString = writer.toString();

OutputStream os;

byte buf[] = xmlString.getBytes();
os = new FileOutputStream("output.xml");

for(int i=0;i
os.write(buf[i]);
}

os.close();
buf = null;




Modifications to the code so that the output xml file is properly indented.



TransformerFactory transfactory = TransformerFactory.newInstance();

// code for indenting
transfactory.setAttribute("indent-number", new Integer(2));

Transformer transformer = transfactory.newTransformer();

// code for indenting
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
