Hi Mark, The good point about your post and the challenge is that it made me re-discover XForm. IN fact I re-discovered why I need XForm instead of simply the XML document, an XSLT stylesheet and a bit of prototype based programming (ref: http://en.wikipedia.org/wiki/Prototype_based). In fact the problem occurred when I tried to bind a particular element from the source XML document to an XHTML element; I am not able with XSLT 1.0 to obtain the XPath expression of a node. So it seems that I need to do it by hand and define it somewhere. This is precisely the kind of functionality offered by XForms :-) By the way, I may be wrong but in the XForms example you provided could the binding be as follows: <xforms:model> <xforms:submission id="submit" xforms:replace="all" xforms:action="http://mydomain.com/MyStorage" xforms:method="PUT"/> <xforms:instance id="theChallenge"> <demo xmlns=""> <version/> <author> <name/> <email/> </author> <description/> </demo> </xforms:instance> <xforms:bind id="version" nodeset="//version" constraint=". = '1.0'"/> <xforms:bind id="name" nodeset="//author/name"/> <xforms:bind id="email" nodeset="//author/email"/> <xforms:bind id="description" nodeset="//description"/> </xforms:model> In which each XML element is referred by an XPath 1.0 expression and I need to include a "bind" attribute to each XHTML element used to input data. For instance, the XHTML element used to input the <version> element will include the "bind" attribute as follow: <input bind="version" type="text" name="version" size="20"/> (no <label> element, this is an XHTML element) In this last case, the "bind" is redundant with the "name" attribute and I guess that the "bind" attribute can be omitted and replaced by the functionally equivalent "name" attribute. Anyway, it could be useful to trace back the binding "explicitely". I can write this whole XForms definition differently as follow: xforms:model> <xforms:submission id="submit" xforms:replace="all" xforms:action="http://mydomain.com/MyStorage" xforms:method="PUT"/> <xforms:instance src=http://myDomain.com/theChallenge.xml" /> ..... ..... <input ref="//version" type="text" name="version" size="20"/> Cheers Didier PH Martin http://didier-martin.com
