Hello everybody
the code line
<span style="color:#2b91af XmlNodeList nodeList = doc.SelectNodes(<span style="color:#a31515 "//trkseg");
returns an empty XmlNodeList. This is how the xml file starts:
<span style="color:#0000ff <span style="color:#0000ff <span style="color:#0000ff <font color="#0000ff
<?
</font>

if I remove the all the attributes in the <gpx> node, the result is the one element <trkseg> as expected. I probably have to use an XmlNameSpaceManager, but I dont know how.
Thanks for any hint!
