Re: [Hypercontent-users] Adding a custom editor

[Alex V. <av...@co...>]

Hi John,
	The most straightforward way of dealing with custom XML files in =
=20
HyperContent is to define the format as a DTD, which will then be used =20=

to automatically generate the web forms.  You can then reference that =20=

data from any other page as an XML include, or by using the XSL =20
document() function during the transform.  I would recommend starting =20=

there; you can add a custom GUI for editing release XML files later, if =20=

you feel it would be of some benefit.  I will work on some =20
documentation on how to go about creating custom GUIs.

Your dtd might look something like

<!ELEMENT releases (release*)>
<!ELEMENT release (label,date,download,description,type?,md5?,notes?)>
<!ATTLIST release version CDATA #REQUIRED
	stable (true|false) 'false'
 >
<!ELEMENT label (#PCDATA)>
<!ELEMENT description (html)>

etc . . .

and your doc(type)

<xml-doc definition=3D"/config/dtd/releases.dtd" root=3D"releases" =20
path=3D"/releases.xml"/>
