AbtDOMDocument>>importNode: malfunction

[MartinCz]

Hi.

I don't know if this is the right place to report a suspected bug, but:

The AbtDOMDocument>>importNode: method declares to do the following:

"Imports a node from another document to this document. The returned node has no parent
(parentNode is null). The source node is not altered or removed from the original
document; this method creates a new copy of the source node. "

It neither changes the parent nor the ownerDocument of the nodes. Is this problem known? Is there any workaround?

Thank you for any answers!

Hello,

Can you provide some code or context as to what you're trying to do?

Thanks.

Hi,

sorry for the late reaction,

here I send a minimalistic example of the malfunction:

Code: Select all

| parserA parserB xmlStrA xmlStrB xmlDocA xmlDocB nodeC nodeW imp |

self halt.

parserA := AbtXmlDOMParser newNonValidatingParser.
parserB := AbtXmlDOMParser newNonValidatingParser.

xmlStrA := '<?xml version="1.0"?><a><b><c>ccc</c><d>ccc</d><e>eee</e></b></a>'.
xmlStrB := '<?xml version="1.0"?><v><w><x>ccc</x><y>ccc</y><z>eee</z></w></v>'.

[ xmlDocA := parserA parse: xmlStrA  ] when: SgmlExceptions::SgmlException do: [].
[ xmlDocB := parserB parse: xmlStrB  ] when: SgmlExceptions::SgmlException do: [].

nodeC := (xmlDocA getElementsByTagName: 'c') first.
nodeW := (xmlDocB getElementsByTagName: 'w') first.

imp := xmlDocA importNode: nodeW deep: true.

nodeC appendChild: imp.

self halt.

Calling the method >>appendChild invokes an error stating that the ownerDocuments are not the same and so it cannot proceed. In my opinion, the method >>importNode should make sure this error is not invoked.

I found that if I put the following two lines of code before calling >>appendChild, it works fine:

Code: Select all

imp elementOwnerDocument: xmlDocA.
imp parent: nil.


The documentation for the >>importNode:deep: method says the following:

Imports a node from another document to this document. The returned node has no parent (parentNode is null). The source node is not altered or removed from the original document; this method creates a new copy of the source node.

What do you think about this?

Thank you!
