I am using XMLReader in C# to read value of each acctNum but the problem is it skips record.

It will skip 1st record, then read 2nd, then skip 3rd, then read 4th and so on.

<acc><acctNum>123</acctNum></acc>  
<acc><acctNum>456</acctNum></acc>  
<acc><acctNum>789</acctNum></acc>

How can I read values of all acctNum from above XML?
