WebTop XML editor supporting operations on views generated by user-defined styles

We present a WebTop XML Editor by which the user can edit XML documents on views generated by user-defined styles. Meta XSLT is the key technology of this feature. Meta XSLT converts a user-defined XSLT into a new XSLT which generates an editable HTML instead of a simple HTML. The user does not need to program complicated editing functions, and needs only to describe the XSLT considering the appearance of the view. Furthermore, we show the effective usage of this editor to browse and/or edit multiple XMLs on the same screen.
