Create Quick Mockups – Balsamiq

I was looking at making quick mock-ups. Came across this interesting little tool

Balsamiq Mockups http://www.balsamiq.com/

I tried to create a simple mockup to explain my friend about creating a simple web-page layout. It just took me 5 minutes to do it and send the screenshot to him. (No more paper drawings, scanning it and emailing.)

No need of installing any new toolset, not high on memory, no need of expensive toolset like visio, etc.

What Visual Basic did for GUI programming will be what Balsamiq is for rapid prototyping.. I simply love this awesome tool. The below example just took me 2 minutes. Check this out for you to know to more about this tool.

Xpath: Get Distinct node values in Xpath

Xpath to select nodes with distinct attribute value 

Getting a list of nodes with distinct value in an attribute using xpath . The key is to use the preceding keyword.

The Xpath query will return only the distinct nodes. I used sketchpath to learn/arrive at the this example Xpath Query. This is is similar to the Regex editor we use for Regular Expressions.

Example Xpath Query: //Schedule[not(./@SourceID=preceding::Schedule/@SourceID)]

Sample Xml:

<ns0:Listings xmlns:ns0="http://myTest.Namespace">
        <Program ProgramTitle="Program - 1025">
            <Schedules xmlns:ns0="http://Mytest.Namespace2">
                <Schedule SourceID="123"></Schedule>
        <Program ProgramTitle="Program - 1225">
            <Schedules xmlns:ns0="http://Mytest.Namespace2">
                <Schedule SourceID="123" ></Schedule>
        <Program ProgramTitle="Program - 1405">
            <Schedules xmlns:ns0="http://Mytest.Namespace2">
                <Schedule SourceID="124"></Schedule>
        <Program ProgramTitle="Program - 1505">
            <Schedules xmlns:ns0="http://Mytest.Namespace2">
                <Schedule SourceID="145"></Schedule>
                <Schedule SourceID="146"></Schedule>
        <Program ProgramTitle="Program - 2005">
            <Schedules xmlns:ns0="http://Mytest.Namespace2">
                <Schedule SourceID="225"></Schedule>
