failed to read data from xml file using c#

I need to read all these data from xml using C#. I already tried but cannot read data like below:

paye :01,category : 1111,ammountALL : 98.000 ,invoice : inv01,order : ord1,date : 2008-07-10T07:08:34, amount: 99.000

paye :01,category : 1111,ammountALL : 98.000 ,invoice : inv02,order : ord2,date : 2008-07-10T07:08:34, amount: 120.000

Following is the XML:
