How do I compare attribute to a lower case value?

Question

How do I create a filter where the attribute value is lowercase?

This works:

xmlItem = xml.*.(attribute("name")==propertyName);

But this is throwing an error:

xmlItem = xml.*.(attribute("name").toLowerCase()==propertyName);

Answer 1

It looks like I have to use toString() to get the String object and then I can use toLowerCase():

var xmlList:XMLList = xml.*.(attribute("name").toString().toLowerCase()==lowerCasePropertyName);
