[Tclxml-users] tclDOM: how to free memory after removing a child ?

[Sreng T. <sre...@ax...>]

Hi,

here is a code I tested. After removing a child from the DOM tree, I try

to free the child from memory.

---------- destroy.tcl
package require dom

set doc [dom::DOMImplementation create]
set root [dom::document createElement $doc top]
set node1 [dom::document createElement $root node]
set node2 [dom::document createElement $root node]

puts $node1
dom::node removeChild $root $node1
dom::DOMImplementation destroy $node1
puts [dom::DOMImplementation serialize $doc]

-------
That doesn't work at all!  The following error message is displayed on
my shell:


::dom::document1(node4)
invalid token "::dom::document1(node1)"
    while executing
"GetHandle documentFragment [lindex $args 0] node"
    ("serialize" arm line 7)
    invoked from within
"switch -- $method {

        hasFeature {

            if {[llength $args] != 2} {
                return -code error "wrong number of arguments"
            }

            # Later on, could u..."
    (procedure "dom::DOMImplementation" line 5)
    invoked from within
"dom::DOMImplementation serialize $doc"
    invoked from within
"puts [dom::DOMImplementation serialize $doc]
"
    (file "destroy.tcl" line 13)




Do I use the destroy function correctly ?


Thanks for your help.
