Hi,
A quick FragmentParser for your convenience ... (not seriously tested).

I was sort of hoping that there would be more 'integrated' approach that
did not require manipulating the XML as a string, such as being able to
pass a list of namespaces to the Document constructor, or build an
element from an xml fragment, but the approach described here is what I
am now using.
Thanks.

Commonly fragments have multiple "top-level" nodes, which may mean that
you also need to wrap them all in a "fake" container element to make the
document parsable (unless JDOM has a document fragment parser - which I
don't recall seeing and can't find).
Handling this is similar to what Per said, but you need detach all the
content from this "fake" root element and add it into the target
document and the required point(s).

Hi,
For each fragment, build a valid XML string (with namespace
declarations), parse it, detach the
single child of the root element and insert it in the target document.
Or did I miss anything?

?mne: [jdom-interest] Building documents from XML fragments
Hi,
I am wondering what is the suggested way of building an XML document
from fragments of XML.
The xml is returned from a remote server in response to an XPath query -
in particular there is
a problem because the server does not return the namespace prefix
declarations in the fragment,
which means the document builder throws an exception
Exception - org.jdom.JDOMException  : Error on line 1: The prefix "erm"
for element "erm:loco" is not bound.
I would like to take the XML string and incorporate or merge the
fragment into an XML document
in memory, and/or create a new one from it.
I have access to the XML namespace bindings, but I cannot see how I can
tell JDom about these
without creating a skeleton document - and then I cannot see how I can
'import' the remaining
fragment into the document.
Regards,
Ed.
