Hi,
I am having trouble getting the maximum value of an attribute as an integer.
Given this xml, how can a LINQ to XML query return 51. (The max as an integer).
<xmlroot><element1 Value="8" ></element1><element1 Value="11 </element1><element1 Value="51 </element1></xmlroot>
My query so far:
<span style="font-family:Consolas; color:#0000ff; font-size:x-small <span style="font-family:Consolas; color:#0000ff; font-size:x-small <span style="font-family:Consolas; color:#0000ff; font-size:x-small <font face="Consolas" size="2" color="#0000ff <font face="Consolas" size="2" color="#0000ff <font face="Consolas" size="2" color="#0000ff
var
</font></font></font><font face="Consolas" size="2" color="#0000ff <font face="Consolas" size="2" color="#0000ff
