From your post, it looks like trk is on the same level as gpx? So, you would have myArray["trk"] Then the next level.. it looks like your trkseg and trkpt[] are on the different levels. (hard to see from the email, but they pretty much have to be) So, you would have myarray["trk"]["trkseg"], and could do an easy repeat for each at that point.
repeat for each key tKey in myarray["trk"]["trkseg"] do whatever with myArray["trk"]["trkseg"][tkey]["time*"] end repeat Another option to simplify would be to: put myArray["trk"]["trkseg"] into myNewArray and then you can repeat for each key tKey in myNewArray do whatever with myNewArray[tKey]["time*"] end repeat If you need to pull out the data in numeric order (based on [1001] in the brackets, you can put the keys in question into a list and do a sort put the keys of myArray[whateverleveltostartat] into tKeys set the itemdelimiter to "[" sort lines of tKeys numeric by item 2 of each then just repeat for each line tLine in tKeys and pull the data out as above using tLine as the key in question On Sat, Mar 14, 2015 at 7:21 AM, Graham Samuel <livf...@mac.com> wrote: > Thanks to help from this list, I’ve used Trevor’s ‘ConvertXMLtoArray’ to > convert an XML file into a multidimensional array.
