RE: [xmljs-users] deep copy nodes between xml documents with JS

[Barry B. <Ba...@al...>]

ah ha!

now I'm cooking! thankyou James (and also David)

xmlFragment =3D parser.loadXML(xmlToAdd.xml.toString());

where "xmlToAdd" is the ActiveX xml doc and the parser is the w3c vers
(I gave up on the classic - sorry)

all I gotta do is turn "xmlFragment" (not a real DocumentFragment yet)
into something I can insert into the master=20

there isn't really a copyNode(deep) or insertFragment(node) is there...
...any suggestions? perhaps loop over each xmlFragment.ChildNodes and
.attributes, adding them to the master (using createTextnode,
createAttribute, etc)?

thank heaps

PS:

[James and David:]
the penny has (finally) dropped re: diff xml implementation, so much so
that (later) I'll convert the ActiveX version to the W3C version as soon
as the xnlhttprequest retrieves the data (at the moment I'm doing it
before populating the form - my bad). I'll do the same with the firefox
version when I get that working.

Barry,

Try dumping the DOM obtained via XmlHttpRequest to an XML string and
then=20
loading the XML into a new document in <XML for Script> to get it into
the=20
proper implementation. ;)

Thanks,
James
