Thanks for the response, John. However, if I don't set the prefix the added
element
just shows up in the default namespace when the document is output as text. Am I
missing something here?
The original code generated the correct XML output document text for all the
cases I
tried, but I didn't look at the internal state (only the output). I guess what I
really should do to make this correct is use the prefix from the parent element
to
construct the name of the new element (if the prefix is not null), then always
use
createElementNS to create the new element:
String name = (prefix == null) ? "text" : (prefix + ":text");
Element text = doc.createElementNS(element.getNamespaceURI(), name);
Any problem with that?
Thanks again,
- Dennis
