Re: [Tclxml-users] Move node from one tree to another

[Moisei R. <mra...@il...>]

Hi,
I've used "::dom::document importNode" function in the same case, check
whether this function exists in your dom implementation.
Pay attention the deep option is boolean and means recursive/not recusrsive
import but not the real deep level.
the sample is like following:

set xmlStr1 {<DOC1> <E11 a1="1"/> <E12 a2="2"/></DOC1>}
set xmlStr2 {<DOC2> <E21 a1="1"/> <E22 a2="2"/></DOC2>}
set doc1 [::dom::DOMImplementation parse $xmlStr1 -parser expat]
set doc2 [::dom::DOMImplementation parse $xmlStr2 -parser expat]
set origNode [::dom::document cget $doc2 -documentElement]
set importedNode [::dom::document importNode $doc1 $origNode -deep 1] ;#
deep is boolean
set targetNode [::dom::document cget $doc1 -documentElement]
::dom::DOMImplementation destroy $doc2
dom::node appendChild $targetNode $importedNode
::dom::DOMImplementation serialize $doc1

and here is with the results:
% set xmlStr1 {<DOC1> <E11 a1="1"/> <E12 a2="2"/></DOC1>}
<DOC1> <E11 a1="1"/> <E12 a2="2"/></DOC1>
% set xmlStr2 {<DOC2> <E21 a1="1"/> <E22 a2="2"/></DOC2>}
<DOC2> <E21 a1="1"/> <E22 a2="2"/></DOC2>
% set doc1 [::dom::DOMImplementation parse $xmlStr1 -parser expat]
node1
% set doc2 [::dom::DOMImplementation parse $xmlStr2 -parser expat]
node7
% set origNode [::dom::document cget $doc2 -documentElement]
node8
% set importedNode [::dom::document importNode $doc1 $origNode -deep 1]
node13
% set targetNode [::dom::document cget $doc1 -documentElement]
node2
% ::dom::DOMImplementation destroy $doc2   ;# the imported node exists even
after the original doc is destroyed
% dom::node appendChild $targetNode $importedNode
% ::dom::DOMImplementation serialize $doc1
<?xml version='1.0'?>
<!DOCTYPE DOC1>
<DOC1> <E11 a1='1'/> <E12 a2='2'/><DOC2> <E21 a1='1'/> <E22 a2
='2'/></DOC2></DOC1>
%

Enjoy,

Best Regards,

I have parsed two XML documents into 2 trees and I want to move a node (and

its children) from a point in one tree to a point in the other. Cutting the

required node out with "dom::node removeChild" is easy, but when I want to
place it in it's new tree I get an error saying "new node must be in the
same
document".

Well, OK, I was kind of expecting that. What do I need to do to make this
cut/paste work as required?
