Update XML Data by Using Graphical Languages
Ni, W. and Ling, T.W.
To be a full-featured data exchange format, XML should
support not only queries but also updates on its contents.
The new W3C XML update facility has proposed a set of
operators (insert, delete, replace and rename) and
expressions to modify XML data. However, the new
update standard is an extension of XPath/XQuery. As a
result, it requires the full knowledge about complex
XPath/XQuery writing techniques, which is too difficult
for common users to use. In this paper, we intuitively
represent XML update expressions as graphs. Based on
our previous works of GLASS (Graphical query
LAnguages for Semi-Structured data), we make an
extension, named as GLASSU, to support the new XML
update facility. To our best knowledge, it is the world first
graphical language that supports XML updates. |
