pc88mxer,

You've got it. <tag> would normally contain many polygons. Every edge is compared to all others.

Cartographers and surveyors use this method of analysis. It's native to a methodology that is universally employed by a Geospatial Information System (GIS).

The file being sucked-in is a Google Earth KML (Keyhole Markup Language). GE is known in the GIS industry as a "geo-browser" because it does not offer the above proximity analysis, among other things.

Come to think of it...I should have asked if it were possible to have the sub return true on the first occurrence of intersection within each key's values.

Thanks for the reply,

This newbie appreciates it!
