Detailed description

FCD files are XML files. The PathName must be a list of items, not including the XML root tag of the tags where the XML attribute ItemName is to be located. So to extract the FLASH memory size Pathname="device.memory" and ItemName="bytes".

If the ItemName is not found in the specified location then DefText will be returned instead.
