Hi,

thx for ur example. The example works, but not my file. An example of a real file could be:

      <channel description="" group="can" name="light_switch" path="" recordmode="3" type="UINT8" value="0"/>
    </channels>

The problem is that there are namespace (as you can see). But they are never declared and i can not parse the file correctly. So i thought with a small hack (insert in line two the namespace declaration with xmlns:pValue="http://dummies.org" xmlns:content=http://example.org" xmlns:scenario="http://thethirdone.com") but when i try to read the <pValue:scalar parName="parameter_one" type="BOOL" val="TRUE"/> node with its attributes, i get shit ;-) Is my declaration wrong? I can read attributes without namespace without problems, thats not the point, but just the namespaces are stupid.

With this line i can check that i am in the correct line of the file

cout <<

"in the correct line " << cur->line <<endl; // but when i try to read the parName or the type, it is not possible

name =

xmlGetProp(cur,(const xmlChar *)"type"); // name = NULL ??
