Hi,
I've found a big problem (in terms of drastic behaviour change) in the
method SetAttribute() of TXML class. This method was written so:
METHOD SetAttribute( cAttrib, xValue ) INLINE ::aAttributes[ cAttrib ] :=
xValue
while now it is written as:
*-----------------------------------------------------------------------------*
METHOD SetAttribute( xAttrib, xValue ) CLASS TXmlNode
*-----------------------------------------------------------------------------*
Local lRet := .f.
if ! empty( xAttrib ) .and. ! empty( xValue ) <<<<<<<< NOTE HERE
if HB_isString( xAttrib ) // attribute name (key name)
if HHasKey( ::aAttributes, xAttrib) <<<<<<<< AND HERE
HSet(::aAttributes, xAttrib, xValue )
lRet := .t.
endif
elseif HB_isNumeric( xAttrib ) // attribute position (key ordinal
position)
if Len( ::aAttributes ) >= xAttrib <<<<<<<< AND HERE
HSetValueAt( ::aAttributes, xAttrib, xValue )
lRet := .t.
endif
endif
endif
RETURN lRet <<<<<<<< AND HERE
There are several behaviour changes:
a) Now, it's possible to set an attribute using its ordinal position. That's
good, IMO.
b) Now, it's NOT possible to set a new attribute using this method. It only
change the previous value, but returns .f. if the attribute name wasn't
exist. Very bad, IMO.
c) The returned value is now .T. or .F., while before was the setted value
itself, allowing it to be used in a chain. (F.e. xVal :=
oXML:SetAttribute( "Attr", Value ) ). IMO, It's not good or bad itself, but
it's a undesirable behaviour change.
d) Now, if the desired value is "Empty()", then the attribute is not setted.
It causes that values like .F. or 0 are not setted, while they are perfectly
valid, IMO.
Please, may I change it back to the previous behaviour (respecting a) if you
want, but reverting b), c) and d) ). Also, if someone need a method to
change an attribute value without creating it, the actual method can be
renamed as ChangeAttributeValue() or so.
