casting with child_value() #136

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,

Lets say I have an xml

<Array>
  <Array index=0> 1 <\Array>
  <Array index=1> 2 <\Array>
  <Array index=2> 3 <\Array>
<\Array>

Then I write something like to get the 2 element

  .select_single_node("Array\Array[@index='1']").node().child_value()

This will return a string instead of an int.
Is there an built in cast I can use with .child_value() like .as_int() can be 
used with .attribute()?

Thanks,  Sam

No, there is not; you can use the 'atoi' function from stdlib. child_value() 
never returns null pointer, so just doing atoi(n.select[...].child_value()) 
will be safe (zero if selection fails).
