Error inserting XML data into database via LINQ

[rechtbak]

I want to use LINQ to insert some fields in a database. One of these fields contains XML data (GPX).When I run the following code:\[code\] rtlq.GpxData = http://stackoverflow.com/questions/11306055/new XElement(route.GpxData);\[/code\]I get this exception:\[quote\] Name cannot begin with the \[code\]'<'\[/code\] character, hexadecimal value \[code\]0x3C\[/code\]\[/quote\]I would like to say \[code\]route.GpxData\[/code\] has a type string and I converted this type to xml.Here is my whole code:\[code\]public int Save(Route route){ aspnetdbDataContext aspdb = new aspnetdbDataContext(); RouteLinq rtlq=new RouteLinq(); rtlq.UserId = route.UserId; rtlq.SourceName = route.Name; //I have an error here rtlq.GpxData = http://stackoverflow.com/questions/11306055/new XElement(route.GpxData); rtlq.CreationTime = route.Time; aspdb.RouteLinqs.InsertOnSubmit(rtlq); aspdb.SubmitChanges(); int k1; System.Data.Linq.ChangeSet cs1 = aspdb.GetChangeSet(); k1=cs1.Inserts.Count(); TrackPointlinq trlq = new TrackPointlinq(); foreach (var trackpoint in route.TrackPoints) { trlq.RouteFK=route.Id; trlq.TrackTime=trackpoint.Time; trlq.Latitude=(float) trackpoint.Latitude; trlq.Longitude=(float)trackpoint.Longitude; trlq.Elevation=trackpoint.Elevation; } aspdb.TrackPointlinqs.InsertOnSubmit(trlq); aspdb.SubmitChanges(); int k2; System.Data.Linq.ChangeSet cs2 = aspdb.GetChangeSet(); k2 = cs2.Inserts.Count(); if ((k1 == 0) && (k2 == 0)) { return 1; } else return 0;}\[/code\]Would you please help me to solve this problem?EDITSample of XML file:\[code\]<?xml version="1.0" encoding="UTF-8"?><gpx xmlns="http://www.topografix.com/GPX/1/1" xmlns:gpsies="http://www.gpsies.com/GPX/1/0" creator="GPSies http://www.gpsies.com - GpsiesTrack" 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 http://www.gpsies.com/GPX/1/0 http://www.gpsies.com/gpsies.xsd"> <metadata> <name>GpsiesTrack</name> <link href="http://www.gpsies.com/"> <text>GpsiesTrack on GPSies.com</text> </link> <time>2012-06-26T18:58:39Z</time> </metadata> <trk> <name>GpsiesTrack on GPSies.com</name> <trkseg> <trkpt lat="50.81482934" lon="12.90653228"> <ele>305.00000</ele> <time>2012-05-01T00:00:00Z</time> </trkpt> <trkpt lat="50.85364209" lon="12.92404174"> <ele>297.00000</ele> <time>2012-05-01T00:15:27Z</time> </trkpt> </trkseg> </trk></gpx>\[/code\]
