Hello Samuel,
I tried the script
doc=xmlRead("G:/Daten/Navigation/gpxArchiv/testfile.gpx")
recent =getPreferencesValue("/gpx/rte/body/rtept", ["lat","lon"],doc)
xmlDelete(doc)
The file is as below.
The result is:
doc =
XML Document
url: file:///G:/Daten/Navigation/gpxArchiv/testfile.gpx
root: XML Element
!--error 10000
getPreferencesValue: Invalid XPath request.
at line 39 of function getPreferencesValue called by :
recent = getPreferencesValue("/gpx/rte/rtept", ["lat","lon"],doc)
at line 55 of exec file called by :
exec('G:\Daten\Navigation\eTrex10_GPX_Generator.sce', -1)
What am I doing wrong here?
Regards, Jens

Hi,
I want to extract lat, lon and <rte>-name from gmx files. See the
following reduced example:
-----------------------------------------------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8" standalone="no" ?><gpx
xmlns="http://www.topografix.com/GPX/1/1"; creator="MEDIA-TOURS"
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";>

<rte>
<name>route_1</name>
<rtept lat="52.00424932154729" lon="8.875365257263184">
<name>1 Start</name>
</rtept>
<rtept lat="52.00319255643224" lon="8.878369331359863">
<name>11 station</name>
</rtept>
<rtept lat="52.00271700399025" lon="8.879871368408203">
<name>111 destination.</name>
</rtept>
</rte>
</gpx>

lat and lon should be collected as numerical colum vectors, name as
a colum of strings.
Which commands would you recommend? Is reading by mgetl and
retrieving by regexp recommendable?
xmlXPath() is made for parsing xml documents and extracting selected
informations.
getPreferencesValue() may also help. It is based on xmlXPath()

Samuel
