XML Viewer Plus 1.01
XML Viewer Plus is a portable free XML viewer plus editor.
XML Viewer Plus is basically a text editor written specifically for viewing and editing XML files. However it also has the ability to validate the XML structure and format the code.
I created XML Viewer Plus as an editor that would allow you to see and change the code as raw XML because I know that's how most software developers and database administrators prefer to do it.
Due to XML Viewer Plus being specifically for XML files it does not require all the other functionality of text editors and IDEs. This means that XML Viewer Plus is a portable utility that only needs to be one executable file. No installation is necessary.
