Karel XML - Boolean read/write

Hello All,

I have question regarding BOOLEAN variable and read/write from an XML file. I have a xml tag which has an attribute whose value is "1" . At Karel side, I have defined a structure with a boolean variable.

When I read using the XML_SETVAR builtin function in a Karel program into the structure, it is automatically converted to "True". Then after writing this value to another XML file, when i try to read it again, it (meaning "True") is not recognised as a Boolean but as a string.

Does anyone know how to retain the boolean status (either retaining "1" or reading "True" as a Boolean)?

Thanks and Regards

Anand

I create a file and write it line by line with xml tags.

For example like

WRITE file('<TAGNAME ATTRIBUTENAME="',STRUCT.BOOLVAR,'">',CR)
WRITE File('</TAGNAME>',CR)

Inside the STRUCT structure, I have defined a boolean variable which initially gets "1" from my source XML file (somehow converts itself to "True" - I checked this in Roboguide). After seeing the written XML file, I find STRUCT.BOOLVAR = " True" (An empty character at the start. Again dont know why).

Yes, that could be one way. I created a small function just to convert this "True" "False" as "1" or "0" before writing. I just dont understand why FANUC doesnt read "True" or "False" directly as Boolean. Thanks for the input hermann.
