Dear Mark,
My understanding of XML is the following:
<foo/> ; empty - obviously!
<foo></foo> ; empty - possibly unfortunately
<foo> </foo> ; not empty - because end tag does not immediately follow
start tag
Except for attributes I don't think XML itself says much about whitespace
handling. XML schema on the other hand says quite a lot! It allows you to
specify on a case-by-case basis whether all whitespace is significant,
whitespace should be replaced with space characters, or whether leading and
trailing whites should be removed and consecutive whitespace should be
collapsed into a single space.
HTH.
Regards,
Pete.
