Well, Richard, I am always very willing to believe that I’ve misunderstood something, but this is what happened (this material is extracted from conversations I had on this list in the middle of March).
1. I had an XML file - it was actually a .gpx file, which shows a geographical route as a series of waypoints. The ‘top level’ of this structure is ‘gpx’. I mean the first three lines are (watch for wordwrap): <?xml version="1.0" encoding="UTF-8"?> <gpx xmlns="http://www.topografix.com/GPX/1/1"; creator="Geolives" version="1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd";> <metadata /> <trk> 2. I converted it to an array using the function ConvertXMLToArray, by Trevor deVore - from Mike Doub’s Master Library. 3. I put the result into an array called ‘gGeneralArray’ - I can see this in the IDE as a nested structure. 4. I executed put the keys of gGeneralArray in the message box, and got the result gpx 5. I discussed this on the use-list, and Mike Bonner suggested > try > put the keys of gGeneralArray["gpx”] > and you'll get the next level of keys. 6. I did that and got wpt[1] trk @attributes wpt[4] wpt[2] metadata wpt[3] I just did this all again to prove to myself that I hadn’t made an obvious error.I am definitely only dealing with one array, so I can’t explain this, and the LC dictionary certainly doesn’t help. Tell me where I went wrong!
