If in your code childList is an array of string, this might help you:

Java

import java.util.Arrays;
import org.apache.commons.lang.ArrayUtils;

string[] childList = new string[];

/// Remove given ChildName from Array
/// returns the removed ChildName, null if nothing removed
public String removeChild(String ChildName)
{
  for (int i = childList.length-1; i >= 0; i--)
  {
    if (childList[i].equals(ChildName))
    {
      childList = ArrayUtils.remove(childList, i);
      return ChildName;
    }
  }
  return null;
}
