Re: [Exist-open] merging XML

[Joe W. <jo...@gm...>]

Hi Alfredo,

It sounds like you're trying to take the input of HTML forms and generate
XML documents from the input. Have you investigated XForms, which can
natively store XML models in the browser and submit XML instances to eXist?
For XForms implementations, see XSLTForms [1] and Fore ("XFormish") [2]. To
learn more about XForms, see Steven Pemberton's tutorial [3].
