[Tclxml-users] possible bug?

Hi,

If there is an entity to be expanded in character data, and if
this entity is embraced, as in:

<body>.can create text 10 10 -text {Hello &quot;new World&quot;}</body>

the resulting parsed character data is not a well formed tcl expression anymore.
The result is:

% $myParser parse $data6
Element start ==> stream
Character data ==> 
Element start ==> body
Character data ==> .can create text 10 10 -text \{Hello }
Character data ==> "
Character data ==> new World
Character data ==> "
Character data ==> \
Element end ==> body
Character data ==> 
Element end ==> stream
% 

If assembling the ch data we get: 

.can create text 10 10 -text \{Hello }"new World"\

which is not a well formed tcl expression. I think the reason is that the character
data callbacks are split up so that entities are reported alone. When tcl handles
an open braced structure, it starts to insert backslashes in a number of places.
Somehow this is not robust, and results in the result above.

Yes, entity parsing can be switched
off by -defaultexpandinternalentities 0 which works (though no entity parsing).
Having tcl code like this is not an example of good structure, and is only
to get things up running fast.

The code was:

package require xml

proc HandleStart {name attlist} {
    if {[llength $attlist] > 0} {
	puts stderr "Element start ==> $name has attributes $attlist"
    } else {
	puts stderr "Element start ==> $name"
    }
}
proc HandleEnd {name} {
    puts stderr "Element end ==> $name"
}
proc HandleText {data} {
    puts stderr "Character data ==> $data"
}
set data6 {<stream><body>.can create text 10 10 -text {Hello &quot;new World&quot;}</body></stream>}

set myParser [xml::parser]
$myParser configure -elementstartcommand HandleStart  \
  -ignorewhitespace 1   \
  -elementendcommand HandleEnd -characterdatacommand HandleText
$myParser parse $data6
