Data type from XML

I’ve pulled in some data into an array but it seems to have pulled everything in as strings. I need to be able to do calculations with some of the data so one element in the array should be a number data type not a string.

Is there a way to assign the data type without using components or to convert the data type?

<name>Cash at bank</name>
<value>108000</value> [COLOR=darkred]<-- Should be a number[/COLOR]

for (var stringNode:XMLNode = childNode.firstChild; stringNode != null; stringNode = stringNode.nextSibling, j++){
accountArray*[j] = stringNode.firstChild.nodeValue;
