Re: XUpdate extensions or XUpdate document

by Adam Retter-3 :: Rate this Message:

Its really about how you are parsing the response from the form used
to update the data and how you wish to do this, i.e. if I was asking
the question between these two scenarios -

1) How easy is it to parse/transform the html form name=value into an
XUpdate document

2) How easy is it to parse/transform the html form name=value into
XQuery update statements

I have written systems for both scenarios.

In (1) we had a naming convention for our html form elements that was
the XPath of the nodes in the documents with "/" mapped to and from
"_" for the sake of HTML correctness. This was fairly easy, pull out
the XPaths and values and build an XUpdate document in an XQuery and
then execute it against the appropriate collection.

In (2) we had a huge load of nexted if, if else, else statements in an
XQuery that acted on the name=value pairs to determine whether to
update the value, remove the node, or create the node with value.

Thanks Adam.
