by the way .. what for ?

[Nate.H]

Mostly to demonstrate string parsing. A little because it was just fun. A little more because it was a start on creating a useful tool for showing a webpage's relation to other pages within a large online space such as ni.com. With a core structure similar to this VI, you can create a relational hierarchy that looks similar to the VI hierarchy and helps with content placement for products, content linking for relevant searches and support, etc...
