XML Notepad: Where can I get it? What can it do for the new XML users?

Hi all,

I am new in using XML in the Microsoft Windows 7 Enterprise - Network Computer System. I have Microsoft Office 2007, SQL Server 2012 Management Studio and Visual Studio 2012 Express in my PC that are housed in the Microsoft Windows 7 Enterprise - Network Computer System.  I just heard XML Notepad and XML Notepad Design. Where can I get XML Notepad? What can it do for the new XML users? I am learning (i) how to read the .XML files in general, (ii) how to create the XML table files for XML databases in Access 2007, (iii) how to use XSLT, and (iv) how to extract/query the desired elements/data in the XML (or Access) databases.  Please kindly help, answer the above-mentioned questions and respond.

Thanks in advance,

Scott Chang
